Hey, I’m just getting started with Homeassistant and I will have some Arduinos with sensors that will send data to HA. But the sensors need two calibration values and I want to be able to send those from the Arduinos to HA to store them there incase I want to reflash the Arduinos.
What would be a good way to set it up? I have managed to send the calibration values with MQTT to HA and store it as helpers. But its quite time consuming as I (think) need to create the helpers manually.
