(This is part 4 of my home automation blog series. See the automation category for the whole set) So, we have control of the HestiaPi Classic from OpenHAB, now it’s time to add some sensors and automate the control of the heating. OK, OK, it’s been a really long break from posting. What can I say, life kinda smacked me with a bunch of family issues. That’s all settled down now, and with winter coming on fast, it’s time to sort out the last mile of my open source heating system - responding to temperature sensors.
