DIY and HA (lemmy.zip)

A little question for the HA and DIY crossroad. Has anyone here made your own sensors/devices with arduino, pi or some other microcontroller/sbc to interact with HA? I have some spare parts around and I'm thinking in something simple, like an air quality, maybe a little weather station or something to tell me if the garage door is opened or close, something simple, yet usable. I had a look on instructables, but I wished for something that would integrate with my first HA experience. Any thoughts?

Edit: thanks everyone for the replies. If you could share how-tos to this projects or anything it would be awesome. You are a great community indeed! :)

I have lots of temp/humidity sensors. I use them to control heating zones instead of the traditional thermostats.

I've become a big fan of the Adafruit BME680, but it's pricey compared to other sensors. But, you get temp, humidity, pressure, etc. Very accurate, too.

The sensors are connected to D1 Mini boards. The dry contact switches I use are in a 4 switch device from Sonoff (4CH Pro, I think).

I prefer Tasmota to ESP Home, but it's personal preference.

You could easily control your own contactors instead of using a Sonoff device if you want.
