IOT: Switching a Chamberlain MyQ WiFi garage door opener WiFi network

When our garage door opener died our service guy installed a LiftMaster Contractor Series Garage Door Opener. I think it’s an 8155W, 8164W or 8165W.

You can enable smartphone app access to monitor and control the garage door — assuming your home WiFi extends that far. Yeah, it’s Internet of Things (IOT) device.

There are obvious problems with doing enabling wifi access:

• Chamberlain security is probably fairly typical. As in … lousy. Assume whatever credentials you use to setup this account are now public. Also assume that the garage door is accessible by anyone who wants in badly enough.
• Even if there are no known exploits in the device OS (hah-hah) it will never get updated. So there will be exploits eventually.
• It’s made in China. Presumably it comes with a backdoor.
• The standard setup is to connect it to your home network. Which means you are, basically, toast.

On the other hand an additional remote is $50 and you can set alarms if the garage door is open after, say, 10pm.

Our garage is not connected to our home, but our Apple AirPort Extreme does reach it. So, despite the risks, I did an initial experimental connection and installed the LiftMaster.app.

It worked ok, so I enabled the Guest network on my AirPort and decided to switch it over. I couldn’t find documentation on how to switch to this network though.

The web page of an error message did give one way to force it to connect:

MyQ Wi-Fi Garage Door Opener: press and release the round yellow Learn button three times on the opener's motor unit. The motor unit's blue LED will be blinking on and off and the opener will beep once.

It turns out there is documentation in the product manual (available online), it just doesn’t contain the keyword “reset”. Instead it uses “erase”. To erase/reset the WiFi network you need to use the controls on the opener, not the remote. There’s an “up arrow” called an “adjustment button”. Press and hold it until 3 beeps are heard. Then start over with the WiFi. (I ran into some issue and Chrome seemed to work around it, so if Safari doesn’t work for you …)

The garage opener is on my Guest network now, so theoretically isolated from my home network.

Things old persons don't understand -- what happens to all those school Google Docs?

Two of our kids are ending their St Paul Public School careers. Both have a collection of Google Docs.

The school does not seem to provide any mechanism for mass reassignment of document ownership to a personal Google account. From what I can tell the school actually blocks ownership reassignment. (Ownership management is one of the several significant issues with Google’s document sharing infrastructure [1].)

So what do students do with all those documents [2]? Olds like me have no idea. They don’t just let them all evaporate … do they?

(I use CloudPull, one of my favorite macOS apps, to create a local repository. The download process converts Google “docs” to Office files. Of course there’s nothing like this for iOS.)

- fn -

[1] Only owners can truly delete an owned document, and ownership cannot be transferred for non-Google “docs”. I think all own/share privileges are at the document level, but documents may inherit some properties from their folder “container” — but not ownership. Yeah, I don’t understand this. Not sure anyone does :-).
[2] Due to some cognitive disabilities and temperaments my guys can’t answer this question… I guess I should ask my daughter …

Update: of course I just write this and today I get for all my CloudPull accounts: “CloudPull was unable to export your backups”. It turns out CloudPull had lost track of my backup directory. I don’t know why. I relinked in Preferences:Advanced and it worked again. It didn’t write anything to console when that happened. Support was great at helping me fix this.

Update 8/26/2018: I again ran into “CloudPull was unable to export your backups”, this time on my personal (36GB export) gDrive. I cleaned up some other non-active accounts, used Help force reindex, and booted into Recovery mode and ran 1st Aid (it fixed things). Then it worked.

Enabling SPF on Dreamhost accounts

Dreamhost writes about SPF:

SPF overview – DreamHost

… Mail servers that receive an email for delivery can check SPF by comparing the sending server’s IP address against the email's envelope sender's SPF DNS record. If the email was sent from a server that is not included in that SPF record, the email is more likely to be spoofed or untrustworthy. The receiving mail server may handle the email differently because of the SPF failure, such as marking the email as spam or rejecting the email…

and

What SPF records do I use? – DreamHost

If you’re hosting your email at DreamHost, no changes need to be made to your SPF records. DreamHost’s SPF records are generated automatically and should work without any issues or additional changes.

IP's in DreamHost’s SPF records include mail servers and the relay machine IP addresses.

Except this isn’t true. When I was investigating my family’s Google email Hell I found that emails sent from DH Webmail didn’t have SFP records in the header. I tested using mxtoolbox.com, Kitterman, and by inspecting emails in Gmail using the ‘view original’ option. I also directly inspected my DNS settings. No SFP.

When I asked DH tech support admitted their documentation was wrong and responded (emphases mine):

If it were, you'd see the SPF setup on the 'Manage Domains' > 'DNS' pageby default for every domain hosting mail with us along with the DKIM
 that's already there, but SPF is NOT set by default (at this time).

… we should start setting it by default, so that info above may be accurate in the future. We’re doing a lot with emails right now, which is still mostly in the discussion phase, so this is likely something that’ll come up as well what with various hosts starting to strengthen their incoming filters to help stop spam.”

For the domain in question, I’ve added the record for you through the 'Manage Domains' > 'DNS' page as a TXT record:

… We have now added the TXT record for .faughnan.com with value v=spf1 include:netblocks.dreamhost.com. Our DNS servers will start serving this
record within a couple of minutes.

My DNS records now show an SFP TXT record:

v=spf1 include:netblocks.dreamhost.com

Unfortunately adding the SPF didn’t help with Google treating my DH redirects as spam. I have a hunch those come from DH’s own SMTP service (homiemail) and that service might have a reputational issue with Google, but I don’t really know what’s going on. I don’t think anyone does any more.

What about DKIM?

DH claims DKIM is set automatically and I can confirm that works, at least for a domain that was relatively recently added to DH. On the other hand when I examine that domain’s DNS settings I see several records not in my older domain. I wonder if DH has never updated DNS settings for older domains, such that they are now obsolete. OTOH, even for a new domain there were no SPF records.

And then there’s Google domain verification (postmaster services). I turned those on my adding their key to a TXT field, but a few days later it wasn’t there any more. I assume DH removed it. I’m kind of losing confidence in Dreamhost.

Google sent my family into email Hell. This is how we climbed out.

… we’re living in a time when algorithmic software is just good enough to eat the world and still bad enough to be endlessly frustrating. (Daniel Genser, via Twitter)

A few days ago I sent an email to Emily and a few seconds later this came back:

Mail Delivery System <MAILER-DAEMON@homiemail-mx1.g.dreamhost.com>
Tue, May 8, 9:52 PM (4 days ago)

Google had sent me to email Hell. Everything I sent to Emily was rejected. It was the same story with emails sent to my children. Whatever I sent, Google rejected.

I think the problem, as far as Google was concerned, was that I was using redirects. This is old net tech. If you own a domain, say “kateva.org”, your hosting service will usually let you define as many redirect “email addresses” in the domain as you might want. They aren’t real email addresses though, they’re redirects. You have to define a true email recipient for each one.

Google didn’t see the email I sent Emily as coming from my personal gmail account, it saw it as coming from the SMTP service that works with my domain (which I’ll call “kateva.org"); in this case homiemail-mx1.g.dreamhost.com. It appears either my domain, or that sending service, had bad Google-karma [1]. Google sent the rejection to “homiemail” (I think!) and homiemail sent it to me.

We were in trouble. It was likely that email sent to our family members was going to be bouncing back in a very confusing way.

I tested sending from various email addresses and using various software (web client vs. iOS Mail, etc) to see which was rejected and which accepted:

Sender	Redirect	Result
GSuite (web client)	Yes	Success
Yahoo (web client)	Yes	Success
Gmail (web client)	Yes	Success
GSuite (macOS mail, iOS mail)	Yes	Success
Gmail (macOS mail, iOS mail)	Yes	FAIL
Gmail (macOS mail, iOS mail)	NO	Success

It turned out my mail was only hitting Google’s spam threshold when I sent it from my personal Gmail (not GSuite email) using iOS or macOS Mail. Everything else worked, including using my personal Gmail by web interface.

No, I don’t understand what’s happening here. I can speculate that Google rates sending services roughly as follows: GSuite_web > Gmail_web, Yahoo_web > GSuite_client > Gmail_client. The combination of Gmail_client (macOS Mail) and the redirect dropped my email score below Google’s internal cutoff.

There’s not much to do about this. It’s not like Google is going to help. I was on my own and we were in trouble.

The first thing I did was change the redirects to send all the mail to an old school Dreamhost local webmail box. That stopped the bouncing. I could forward from that box to my gmail and reroute important emails manually to other addresses for Emily and the kids.

Next I discovered, contrary to their documentation, that Dreamhost had not enabled DKIM or SFP on my domain. I fixed that (separate post pending) to see if it would improve the reputation score for my domain but it had no effect. I suspect the reputation that mattered was that of homiemail-mx1.g.dreamhost.com.

That left me with these options …

1. Setup Dreamhost mailboxes for each person and create redirects to them.
1. Set up a forward from the DH mailbox to another of our family GSuite emails (I picked several Google Apps/GSuite things when they were free)
2. Have our family GSuite emails do POP retrieval from the DH mailbox.

Dreamhost recommended the 1.2 (second). But I had a third option…

… even though I’d not used it, the problem domain (“kateva.org”) had an old legacy GSuite. I went into that GSuite, defined an account for Emily and kids, and then switched Dreamhost MX to use the GSuite email rather than DH email [2]. I had lost some faith in DreamHost by that point and I figured that since Google rules the net I was better off inside their castle.

And that’s where we are at the moment.

One more weird thing. For 2-3 family members I received a notice that a non-apps Gmail account already existed for them. I didn’t create those accounts but maybe my kids did? (It’s complicated, but somehow when I did Google Voice for them it did … something … brain shutting down ….) Apparently Google lets one do this! They wouldn’t have received email though, DNS records were using DreamHost MX redirects. If you own a domain, and create Google Apps account that matches the existing address, it gets renamed to something like “username%domainname@gtempaccount.com” email. Wow. [3]

It’s Google’s world, we just play in it.

Oh — and don’t use redirects. Google doesn’t approve.

- fn -

[1] Dreamhost denies that they’re in any kind of trouble with Google — but really, how would anyone know. Maybe it was my domain that Google didn’t like — we get a lot of spam and in this setup all that spam would seem to be coming from my domain.

[2] This wipes out all the past redirects. GSuite supported aliases so I moved them into there. Fortunately I’d saved the redirect records before making the MX switch.

[3] Google has an article on conflicting accounts, here is how they are resolved. I think Google Voice was the primary route for creating conflicting accounts — an artifact of how Google switched Voice credential systems post acquisition. 

Appigo Todo Cloud.app - don't forget to unsubscribe when you leave

Even since iOS 11 editing in Appigo’s Todo Cloud.app has been buggy for me on iPad and iPhone alike. Just aggravating. Feels like they failed to revamp something. I wasn’t delighted with their sync technology, but I could live with that. The editing bugs finally broke me.

So I decided to exit. Somehow I remembered Todo Cloud is a subscription service. I found my way to the somewhat hidden account settings and disabled premium. Turns out that turns off auto-renewal. 

Hope it really works.

Appigo is a textbook example of how subscription solutions can disappoint. They never provided a good export strategy, so there’s a strong data lock. Then they failed to do minimal maintenance but continued to collect subscription revenue and sell the app.

So what will the replacement be? I’d like a product that

1. Did what Appigo ToDo Cloud did but actually worked
2. Had a web client as well as Mac, iPad and iPhone client
3. Supported family sharing
4. Had good data export (exit strategy).

I evaluated Things.app and OmniFocus. Things got #1 and 3. OmniFocus got #1 and 4. Neither got #2.

Hmm.

On the other hand, Reminders.app for iOS got #2 and #3 and it’s free. So it’s weirdly in contention.

For now I’m using Reminders.app for tasks and Trello for projects. I manually copying over tasks that had dates, it’s not too bad. The backlog of ‘someday’ tasks I’ll gradually slog away at.

If Things gets some data export I’ll probably buy it, but it’s expensive since it’s not a universal app. If OmniFocus gets family sharing I might buy it. Meanwhile I’ll see what I can make Reminders do.

I think this is my first significant iOS functional regression.

Update 5/22/2018

I just discovered I wrote about this in 2011 …

There are no great task managers for the iPhone - but there's hope for 2011

… Neither Things, nor Appigo’s ToDo.app (which I have used incessantly since 2008), nor OmniFocus, nor Remember the Milk.app nor Toodledo.app are a great solution. They all fall short…

Seven years later and ToDo.app is moribund (I’ve been using it for 10 years!) and both OmniFocus and Things are still flawed.

Since I first wrote this I’ve run into issues with Reminders.app — including sync bugs and even text editor bugs. On the other hand, OmniFocus is promising a web client. I’m going to transiently switch back to ToDo.app and see if WWDC providers some kind of family sharing for subscriptions. That would make OmniFocus pricing less extreme.

MarsEdit - don't enable all post sync if you have a very large number of posts

MarsEdit 4 added a new feature — the ability to sync all posts. It didn’t work for my Blogger posts, somewhere around post 3,000-4,000 Google Blogger dies. It looks like a Google bug.

It did work for kateva.org/sh though — that has over 30,000 posts (it mirrors my pinboard shares and twitter tweets). Unfortunately that slowed MarsEdit launch severely — it took up to 3-4 minutes to start. Turns out MarsEdit loads all posts into memory and it doesn’t scale to that size.

I reset the kateva.org/sh sync to ‘last 50’ and startup is ok now.

Two possible bugs in iOS 11.3 to watch out for: enable purchases by Touch ID, change iTunes & App Store account

Our kids' phones were setup to use my Store Apple ID (it’s an old practice — see a blog post about undoing this). The phones were set to require the Store Apple ID password prior to purchase. When our kids wanted to buy we’d enter the Store Apple ID password for them. Touch ID was not enabled for purchases. 

After the 11.3 update two of the phones had Touch ID enabled for purchases. Normally you need to enter the Apple Store ID to enable this. One child (special needs) ran up a $10 bill which he paid for. (He gleefully shared his new power with us.). On one affected phone I turned it off again, when I turned it on the Store Apple ID was requested as expected. (Another phone I migrated to using its own Store ID, a third device wasn’t affected.)

On 1 of the 3 phones the Store Apple ID was changed to the user’s iCloud Apple ID. The problem was recognized when my daughter was unable to view movies not on her phone — it took me a few minutes to figure out what happened.

It’s interesting how much behaviors varied between the 3 devices.
