I recently automated my home water heater and like most projects the why didn’t really factor into the decision to automate. So now, that I am able to control the water heater, and good ideas on what to do with the data and how best to control the system other than turning it off when I’m away?
Mandatory project outline and pics:
- xbee S2 connected as a ZHA device
- 2x DS 18b20 temp sensors, one on the inlet and one on the outlet
- CT for current
- 65 amp Solid State Relay (overkill but cheap on eBay)
