I’m interested in building an openHAB compatible power control module that people could use to control things like water heaters, electric heat etc. The need is that in my area solar PV tariffs favor consuming energy rather than feeding it back into the grid so if there was a way for people to control and consume generated electricity it would make solar PV more economical to install.
The overall plan involves this control module being available for use and passing various safety certifications, some kind of openHAB integration to monitor energy flow in/out of the house, hopefully using data from the solar inverter without additional hardware, and software on the openHAB system to use the energy flow and things like Internet connected thermostats in order to control the heater modules. The story is a bit simpler for the electric hot water heater use case.
Does this sound interesting to you? If so, let me know if you’d like to be involved or have any questions.
