Upgrading to eero 6 and HomeKit

A quick word of caution. Although I’m a fan of eero (starting before Amazon bought them), if you’re a HomeKit user, there is an obvious oversight in their software of which you should be aware.

Replacing an old eero device with a new one is easy using the eero app. But, when you delete the old device, the unit is not removed from HomeKit. And once the device is removed from your network, you can’t delete it from your home. You’ll be forever stuck with error messages about “non-responsive” devices in your Home app.

eero tech support confirms that there is no way to fix this after the units are decommissioned. Clearly, their software should either do this for you automatically, or alert you before you shoot yourself in the foot. But it does neither. Fair warning.

Covering a doorknob hole

When we moved into our place, the front gate had a deadlock and a locking doorknob. This combination created some usability problems:

  • the doorknob, when locked, could be easily unlocked by reaching through the fence and turning the dial on the inside knob. This made it silly to ever bother to lock it.
  • when the doorknob was unlocked, it would turn (of course) but if the deadlock were locked, the gate still couldn’t be opened. The state of the deadbolt was inscrutable.
  • there’s no indication which way the gate opens. So, even if both locks were not engaged, you had a fifty-fifty chance of the gate opening when you pushed it. If it didn’t open, you couldn’t be sure why.

I quickly noticed that most visitors struggled with these conditions. Pushing, pulling, turning, and so on, never sure if the gate was locked, or if it was some combination of the three possible impediments. (You can view a photo of the gate in this post.)

To correct some of these issues, I removed the doorknob from the gate. But this created an unsightly problem — there was a hole where the knob used to be. Additionally, because the gate is iron, I wanted to cover the hole to prevent water infiltration.

It was inexplicably hard to find, but I did eventually uncover the two solutions I needed. The first is a plate that covers the hole where the doorknob used to be, and the second is a smaller plate that covers where the latching mechanism used to protrude.

Here’s what I purchased:

I can’t recommend the Door Hole Plate Cover that I used because the bolt that comes in the package is too large to fit through the hole in the cover. (What the hell‽) I had to enlarge the hole to make it work. But perhaps you can find another brand that’s properly designed. The Door Edge Filler (not shown in my photo above) fit perfectly, but you’ll need to supply your own screw to install it.

The best way to catch a water leak before it's too late

A water leak can be one of the most expensive accidents to happen in your home. (Ask me sometime about ABT’s installation of a faulty fridge valve that caused over $20K in damage in our kitchen.)

I recommend you buy several Govee Water Leak Detectors and place them anywhere a leak might occur. The loud alarm could save you a lot of money, as it’s easy for a leak to escape detection until after it has done significant damage.

If you know me as a home automation expert, it might be surprising that these are non-automated, standalone alarms. But this is a perfect example of when isolated, inexpensive, and reliable sensors are the best choice. These are “set it and forget it” simple, and you won’t miss an alert due to network interference or a technology mismatch. Additionally, you can buy five of these for half the price of one automated sensor. (Buy from Amazon.)

That said, if you’re hellbent on unnecessary complications, you can apparently get a hub and an app from Govee that will work with these. Instead, I suggest you just convince yourself that you’re deploying a fleet of autonomous robot guardians, then get on with your life and hope that they only problem they ever detect is a low battery.

Quick fix for the KitchenAid Nespresso Espresso Maker

If you have a Nespresso Espresso Maker by KitchenAid (Model KES0503SZ) then you have likely discovered a minor flaw. Namely, the design of the water tank can make it difficult to see how much water is in its tank.

If you’re experiencing this issue, here’s a simple fix. Drop a cork from a wine bottle inside the tank. It’s easy to spot from the outside and you’ll know exactly how much water is present before you push the brew button.

Aside from this hiccup, I rather like this coffee maker. It’s sturdy, cosmetically matches my other KitchenAid appliances and (most importantly) offers a size setting that is larger than the Lungo that other Nespresso machines have.

Automatically open the printer status window

If you're a Mac OS X (macOS) power user, you should certainly have a copy of Keyboard Maestro. (If you don't stop reading now and go there. You're welcome.) This tiny little trick requires that you have it...

My HP LaserJet printer is not on the same floor as my home office. Therefore, whenever I print something, I like to keep tabs on the print job so I know when it's finished or has encountered problems. Normally, to do this, you have to click the printer's icon in the Dock.

I hate clicking things when I don't have to.

So I wrote what might be the world's simplest macro. It's triggered by the print job starting, then it clicks the monitor apps which causes the status window to open. Brilliant? Not really, but it is very handy. Here's what it looks like:

Cure for a SwitchBot that forgets its schedule

Currently, one of the best home automation devices in my system is the "SwitchBot Button Presser." It looks a lot like a Rube Goldberg device, but it works perfectly for activating non-smart switches. If you're looking to retrofit an existing setup, give it serious consideration. (But be aware, it makes a distinct mechanical noise when operating.) I use them to schedule hallway lights, and I love that they operate independently and reliably.

One of my SwitchBots, however, recently started forgetting its scheduled on and off times. I chalked it up to a glitch or a firmware update, then finally realized that its battery was low. The switch would still operate and communicate, but for some reason, wouldn't save its scheduling. A fresh CR2 battery solved that problem. (And underlined that it's a good idea to keep spares of uncommon batteries.)

Change WiFi settings for Koogeek Power Strip 01US

The Koogeek "smart" power strip is a nice HomeKit accessory, but it appears to be discontinued. If you need to change its wi-fi setting, good luck. The user manual is 404 on the company's website.

After much gnashing of teeth, here's the secret:

1. Before we begin, remove the accessory from your home using the Home app, Holmes.
2. Hold down the on/off switch for Outlet #1 for 10ish seconds, until all the other lights go off and the light for Outlet #1 flashes slowly (mine is green)

Then you can use the Home app to add it to your HomeKit network.

Hint: Outlet #1 is closest to the power cord.

HP Printer Bonjour broken after network change

If you're pulling your hair out over an HP printer that stopped being reachable/visible after you made a network topology change (such as a new router), reset the printer to factory settings and reconfigure it. Some HP models (all?) retain the MAC addresses of network peers. Trust me, it's worth the effort.
