Yes, for sure!
I'm working on an HVAC controlling system based on 3 esp-8266, 2 DHT22 sensor and a dual solid state relay board. For now, my worst problem is the heat generated by the esp8266 that interfere with the sensor reading in a small enclosure... I'm like 13c over the room temperature with my actual reading!
Again, thank you for your help and keep up the good work on Cayenne!
