> And if you want to put more effort in, you could e.g. make your own temperature sensors with a Raspberry Pi and an appropriate chip wired to the GPIO pins.

No need to do that. There are plenty good BACNET/MODBUS sensors, and you can run them over RS485 over CAT5. In my experience, they are utterly reliable and are easy to automate with HA. For example, I've been testing these sensors for over a year now: https://www.andivi.com/sensors/modbus-sensors/modbus-co2-...

If you _do_ want to go the DIY route, I highly recommend using ESPHome from HA, and using ESP32 with Ethernet: https://esphome.io/components/ethernet.html It will provide you with a centrally managed dashboard and automatic updates. Downsides: no VLANs for now, and no IPv6.
