Yes, my old python program to control my heaters is still working. I just had to adapt it to python 3 and modify the code so the old ds1820 sensors aren't needed anymore, I can connect it to my mqtt server. And get the temp from the esp8266 I placed many years ago, all around the house. I've also put a relay on one of them and it works fine.
Oh, and all is running on a Raspberry PI Zero W, powered by NetBSD.
