I actually tried something like this, the laptop BIOS didn’t have any settings to tweak for A/C power changes. However, it does wake from sleep after plugging in. The issue is, it immediately goes back to sleep (within seconds). Tried quite a few things to try to stop that behavior (e.g. running Power Toys Awake) but had no luck.

So that’s when I switched to ESP Keyboard.

Oh yeah I should have specified this is to wake from sleep, not a complete shutdown. So not a complete replacement for WoL.

I was a little surprised as well, but I think it’s because the keyboard / mouse I use (and the ESP32) all use Bluetooth LE specifically.

I looked at USB solutions first actually, but then decided to try ESP Home solution since I was already familiar with the system.

I definitely thought about trying something physical like that too, but mostly as a fallback plan!

It’s an installable PWA, click the … Menu in Chrome browser and choose “install”. Hope this helps!

I use this installable web app for cleaning extra parameters from links - https://linkcleaner.app/

Adds a share target to Android once you install it as well, makes it easy to send links to. Open source too!

Not the OP, but commenting on the Atoms. They are good for testing, but not sure I’d want to use them for a full setup.

For one, speakers are pretty rough in them 😂 That’s kinda to be expected though, it’s intended as a cheap dev device.

However, the bigger thing for me is to wait and see what hardware HA will support when they implement on-device wake-word processing. I’d definitely prefer no continuous audio streaming over the network, until after I have said the wake word.

I picked up an Atom for testing as well. I do get a delay, but definitely not 28 seconds… Maybe more like 4-5?

It’s totally dependent on the speed of the hardware you are running HA on though. Since the microphone is just streaming sound to the server, which then processes it. I’m running on fairly beefy server.

Just for a test, you could also try toggling off the wake word in the Atom Device settings in HA. Then you can send a command by pushing the physical button. Could at least narrow the delay down to wake word processing vs normal speech processing that way?

Great! Yeah it seems like very useful information, hopefully HA will make it more accessible / obvious to access in the future!

Very welcome!

I’ve also never had a Fridge do this (even this one that had gone through multiple power outages).

This one does have a function to toggle off cooling on the front controls, why you’d ever want to do that, not sure… My assumption is something happened during power outage to affect the “brains” of the Fridge, but no idea really.

Yeap, I put it in the actual Fridge, signal seems fine for Bluetooth at least!

If you already have ESPHome and Bluetooth proxies setup, the Govee sensors should be auto discovered by Home Assistant as soon as you put the batteries in!

It is the Govee Bluetooth integration, I was actually amazed how simple the setup was. Didn’t even have to install the Govee app. Definitely give them a try, the price is right!

We’ve had quite a few temporary power outages before and there’s been no issue when it comes back up. I still have no idea what happened this time. Like I said, even power cycling it again was what “fixed” it (at least for now).

You could then call a friend or family member and ask them to check on it.

This is exactly what I had in mind.

Fridge is probably one of the few things I’m hesitant to put on a smart outlet, just because chance of something going wrong with it.

Only thing I’d worry about is maybe one in the basement, behind closed door, and being asleep in 2nd flood bedroom?

Guess it would just depend how light of sleeper you are though.

Water sensors are the big one for me! I have a mixture of old SmartThings ones, and cheap ThirdReality branded ones (that seem to work fine still!)

I definitely have the water sensors covered, even have a water shut-off valve tied to them (that’s the one I’m most paranoid about).

Interesting idea w/ the smoke alarm ‘relay’. I have some echo dots, that in theory are supposed to pick up smoke alarm sounds when in ‘guard’ mode. The water sensors I have throughout the house also have temperature sensors (and I have others from ecobee), I have those send an alert if they ever get way too hot or too cold, and announce that over speakers. In theory that could also help with detection of fires or failed HVAC, etc…

These are the ones I got, just because they are only $9 each, with a display as well. Each one has 2x AAA battery, so I’d expect they’ll last quite a while. HA also reports on battery level - https://www.amazon.com/dp/B0872X4H4J

They are bluetooth, but I already had an ESP32 for other sensors. Seems to work great w/ Home Assistant / ESPHome so far!

If anyone has other suggestions for possible ‘blind spots’ like this, appreciate it!
