No, no they're not. I would much rather people are warned about the guidelines and adhere to them going forward than the opposite and we then just let violations run rampant.

They're not "warnings". They're passive aggressive internet dick waving virtue signalling. The flag button exists.

I, for one, appreciate knowing why people have flagged my comments. The "flag and move on" strategy is for use against bad actors.

>> The PCB was ordered from JLCPCB, where I opted to have most of the components pre-soldered. very expensive, you are committed! :) you should have gone Full Giertz and added a badd little robot arm that turn the pot. esp32 are really nice: hundreds of code examples that do what you want without having to read too many pages. did you use ARDUINO IDE or idf.py SDK?

My current record is $19 (including shipping!) for two assembled boards of https://github.com/xobs/soundoff which is a little device that shuts off 5V power to a USB-A port when it detects the PC it's connected to goes to sleep.

Good question. I put the Shelly relay in a pre-existing junction box in the basement. Previously, this box worked like this: There were romex cables for power/neutral, lights, and the switch itself all inside of that box. The switch, located elsewhere, interrupted power to the lights. (This isn't necessarily the most-typical arrangement, but it's how it is in the house I've got.) Currently, the box works like this: W…

My only fear is my HA box will fail and now nothing works. Most likely because I move and forget to tear everything out. Still something I'm interetsed in

You can run HA in a Docker container and set it to generate backups periodically. If your virtual box (or the host) dies, spinning up a replacement will take up a few minutes, as long as you still have you have a computer capable of running Docker or Podman.

I have the same fear. So everything I automate has a fallback option that exists outside of HA. My regular light fixtures, with smart bulbs? I can turn those on and off using their light switch in the event that Home Assistant is dead, like I would if they were dumb bulbs. (I seldom use them that way, but I can.) And my basement lights have their smarts all programmed directly in the Shelly relay. It works without ne…

Interesting, I had a similar setup with smart bulbs, dumb switches and HA. My experience was that when the bulbs lose connectivity (Zigbee or Wifi in my case) you could maybe still turn them on but they would start flashing like crazy or use different colors (as indicators for their "reconnecting" state). Also Zigbee doesn't really love losing mesh nodes periodically, so turning the bulb completely off using the switch would cause the whole network to fall into broken states that had to be manually fixed from time to time.

Depending on your air filter you might be able to just use a smart plug, I went down a similar route this summer before realizing that mine would remember their power state and settings when powered off. So now I just have them plugged into a few smart plugs with automations in homeassistant

I would need a device with a physical switch rather than a touch control. Sadly many devices, mine included, have "power was cycled = device is off" logic.

ESPHome and homeassistant have been really great, just like a nice breath of fresh air in a world of cloud saas stuff.

It just makes stuff so easy - I’ve been on an absolute spree lately, and have built out:

Ultrasonic tank & river level monitors, with temperature compensation and a battery fuel gauge - managing to make a 3000mAh battery stretch almost a year. Some of the river monitors use LoRa.

Remote control to stop/start the previously pull-start generator

Gas bottle level monitors

Made the coffee machine dangerous

And my current project is seeing if I can make solar/battery powered LED bulbs that I can hang on trees and use BLE to make them automatically turn on some distance ahead of you as you walk down the long path through the forest, and turn off once you’ve passed.

I only really got started a few months ago, and my approach is far more breadboards, DuPont cables and superglue, because I know damned well that the moment I go “ok I’m done let’s get a PCB” I’ll decide on a modification.

Anyway. I don’t have enough good things to say about ESPHome. I get to save thousands of euros, and have fun at the same time. What’s not to like.

I actually like this idea. Makes more sense than smart fridges. Would be cool if this ESPHome thing worked with RP2350/Rpi Pico 2.

Could tie it to a thermometer and turn it on automatically on hot days. Very cool.

Ideal for a beer fridge. Is today a beer in the sun day? If so, chill those bad boys. Otherwise, save the energy.

I purchased a Phillips fan in a shopping spree. It was hot outside, needed something, did not pay much attention beyond that it worked and was not noisy. At home my eyebrows went halfway on my forehead seeing that there is a remote and the remote is supposed to be my mobile! Need to download the app for it, connect the fan to the Wifi, but it also had bluetooth for some reason. No way Jose! Yet, it was so incredibly…

The location access is often needed for the app to be able to find the WiFi networks in the neighborhood. This is because that can be used to triangulate your location, so they bundle it in with the same permission (unfortunately, there isn't a very good way to separate this, since it theoretically can be used to locate you and therefore you should let the user know that).
