For those who’re fortunate sufficient to have central heating and/or air con, with an automated thermostat, you in all probability don’t have to fret an excessive amount of concerning the exterior temperature. However central HVAC is much from the one means of sustaining temperature in a house. From wooden stoves to boilers there are various choices relying in your local weather and residential sort, and [Murphy’s Law] has a decentralized baseboard system as an alternative of one thing centralized. An ESP8266 solution was found that was able to tie them all together.

There are different kinds of baseboard heaters, however in [Murphy’s Law]’s case the warmers had been electrical with a separate thermostat for every heater. Reasonably than construct a management system from the bottom as much as exchange the thermostats, turnkey sensible wall switches had been used as an alternative. These switches occurred to be based mostly on the favored ESP8266 microcontroller, like loads of different off-the-shelf automation options, which meant much less work wanted to be finished on the road voltage aspect and the microcontroller’s firmware may very well be simply custom-made to be used with Residence Assistant.

Whereas [Murphy’s Law] doesn’t dwell within the residence with the fleet of electrical baseboard heaters anymore, the brand new residence has a single baseboard heater to maintain a rest room heat for the reason that central heating system doesn’t fairly maintain it heat sufficient. This technique is ready to scale up or down based mostly on variety of heaters, although, so it’s nonetheless a succesful answer for the only room and has since been up to date to make use of the ESP32. All the code for this venture is available on GitHub as properly, and for these of you trying so as to add different HVAC elements to a house automation system this venture that loops in a warmth pump is price looking at as properly.
