esphome VS fingerprint-mqtt

For the ESP32, an hero is in the process of adding LVGL to ESPHome. You can try it out now: https://github.com/esphome/esphome/pull/6363

Here's the (very good!) preview documentation: https://deploy-preview-3678--esphome.netlify.app/components/...

This is such a game-changer for me that I'll be using the ESP32 over the ESP8266 for any projects involving displays from now on.

Solid state relay is probably a bad idea with all the extra heat-sinking, extra cost, and chance of getting counterfeits.

I do this with ESPHome & a J115F21C12VDCS.9 relay (note only the NO side is rated for 40A resistive): https://i.imgur.com/MqqOkoY.png

Choose any of the temperature sensors here for air temperature sensing: https://esphome.io/

Configuration is so easy. For the sensor, just copy the config from here, for example: https://esphome.io/components/sensor/bme280. Add a gpio output (https://esphome.io/components/output/gpio) and a bang-bang climate controller (https://esphome.io/components/climate/bang_bang.html)

You might want to take a look at https://esphome.io/ for an easy integration of an ESP32/8266 into home Assistant.

You can do this with a $30 Sonoff S31 running ESPHome [0]. Since the Sonoff wall switch can run a ping sensor against your server you could create a watchdog automation right on the S31 to shut off the mains power to the S31 switch and turn back on after X seconds.

There are other ways you could have the S31 do operational checks but ultimately ESPHome is probably an interesting consideration and supported by tons of off the shelf hardware.

They're pretty great and compatible with most things. ESPHome [1] is a great resource for getting ESP32's working nicely with HA and you can find lots of projects using it to learn from.

You'll likely need to do soldering if you want to connect sensors, batteries and the like.

Personally I really like what SEEED Studio [2] does with their ESP32 boards and they have nice docs.

Maybe you could set up ESPHome on the ESP32. It might make connecting those components easier, plus a decent web server built in. Then your app can be set up to access data provided by the ESPHome web server.

# # Setting pins for sda and scl will be required until https://github.com/esphome/esphome/pull/2970 is released

Probably an unpopular opinion, but for the simple stuff you may just want to use something like EspHome where you just need to create a yaml file. Once you’re comfortable with that maybe get into something a bit more advanced, but esphome make it a breeze. It integrates with home assistant if you already have that in place as well.

I've followed this guide in order to get it all setup (however I've ended up using this code to get the LED ring working).
