Heat and solar control

About This Project

Will optimize power and heat used in the house, control solar array position. System was running using PHP and Apache2 and could be monitored from internet but not controlled. Cayenne has made it easy to control from the internet as well as monitor.

What’s Connected

5 Temperature sensors are DS18B20 one wire sensors, Home made current sensor, 4 power relays, Mod 2 pi

Triggers & Alerts

Triggers are used to add heat to the water when excess energy is available from the solar panels.
Also will position array for best view of the sun.
Outdoor fire box is used for majority of heat but when temperature drops a heat pump is started for supplement.


I have no scheduling yet but will be used with seasonal values.
(Did you use the Scheduling feature?)
