Is a raspberry pi 3 b+ sufficient for running home assistant. I have a 3 b regular and a 3b+. Currently using the 3 b+ for pi hole but will swap them around if needed. My setup is pretty small currently 3 light bulbs, 3 Google minis, 1 Google audio, 2 alexas and a nest thermostat. Looking at adding some light switches next. Do they have them that will control a fan and lights seperately?
