We currently only provide control over EV charging. In the next 1-2 years though we expect to remain focussed on building the best EV charging product we can.
It's a common request and it might be something we consider adding support for at some point in future.
There are two alternatives exist that you can use now.
a) When your hot water system is due for replacement (most have an expected life of 10-15 years), replace it with a heat pump system. Such systems often only draw around 1 kW and run for less then 3-4 hours per day. They can be set on a simple time clock to operate during solar generation hours. Often solar production will exceed the load avoiding the need for any automation.
b) If your electric hot water system is relatively new, consider installing a hot water diverter. There are many on the market and some solar inverters include it as an optional feature.
Residential swimming pools are commonly equiped with a 1 kW pump. These can be upgraded to variable speed pumps that operate at around 300 W. Being a very low energy consumption it will comfortably sit within the solar production of most rooftop systems. A simple time clock set to operate during solar generation hours will be sufficient, and avoid the need for automation.
