My setup is simple, HA - Arduino - sensors. There are a lot of techniques and names in this sphere, MQTT, Json, Firmata etc. Can someone tell me if I have any gain of these? ---

The normal setup is HA - ESP Home device - sensor If you want to use an Arduino then you'll probably need to create a custom sensor inside Home Assistant and use MQTT as the message layer. ---

Seems MQTT is not for my gear as it require TCP. Only 'vintage' stuff here. 🙂 Thanks for your input! ---
