I don't use this, personally, but it strikes me as a fantastic idea. I made a sensor board and wrote my own firmware for it, maybe I'll see if I can easily configure ESPhome to run on it.

The only thing I'd need that my thing already has is pull-based OTA updates. Right now I just copy a firmware to a folder, and all my sensors around the house automatically update to that firmware via an HTTP server. With ESPhome, I'd have to push the update to each sensor separately, which is tedious when you have tens of them.

Maybe fewer bugs and need to make changes with this?

I have a fair number of esp devices with temp probes around the house, and I’ve been meaning to switch to esp home so I have less code to maintain

Yeah, definitely fewer bugs. Hopefully I won't mind the decreased flexibility, but the lack of HTTP updates really hurts.

I've got 20+ devices running ESPHome, about 3/4 of them are part of my Home Assistant network, and maybe 6 or so that are standalone and just using ESPHome to talk to MQTT for other stuff (cheap Chinese weather station that I replaced the insides of with an ESP32, etc). I've got my rain water tanks monitored, my soil moisture in my greenhouse, the temperature and humidity in all different parts of the house, air quality in the kitchen and kids rooms, etc etc.

It's such an underrated project. In literally 5 minutes and with $10 of hardware and no programming at all, you can build your own IoT devices in your home and get real-time data on anything you want on your property.

Anyone got this to replace their thermostat? Like sensors in zoneA signal and a device connected to the HVAC triggers ON? Maybe they're on WiFi or Ethernet connection?

Same here, plus a dozen or so random ESP32 variants just sitting in my electronics parts box because they're so cheap. It's incredibly freeing to just have all that hardware available at arms reach whenever you have an idea. They're surprisingly reliable and with modules like the sprinkler controller, they can be programmed to be independent so that they keep running as long as they have power. It took me months to realize that HomeAssistant microSD card had failed last time because all of my hydroponics gear just kept running.

By far the biggest time consumer has been wiring them up to DC/DC converters to drive relays in a waterproof Sockitbox. Another really useful part to keep around are wire terminal breakout boards: https://www.amazon.com/whiteeeen-Development-Expansion-ESP-W...

Also CloudFree is great for off the shelf IoT parts that can be reprogrammed with ESPHome: https://cloudfree.shop/

Made a time clock with ESPHome and a M5StickC. Clock in and out. Home Assistant sends the time to a Google Sheet. Super reliable.
