   Did you opt for ESPHome or Tasmota firmware?   
      
   I use Tasmota, but I use Domoticz rather than Home Assistant. From what   
   I read ESPHome is tailored for Home Assistant and uses REST API rather   
   than MMQT like Tasmota.   
      
   A Pi4 can handle a lot of different services on the same machine,   
   installed in Docker Containers. So you don't necessarily need lots of   
   Pis. If the Pi4 isn't enough, there are more powerful Pis.
