Hi
I’ve create a custom integration for the Askoma Askoheat+ devices.
You find the integration in the following github repository: GitHub - toggm/askoheat: AskoHeat+ integration to Home Assistant
The integration connects to the askoheat+ device through modbus and queries four different data blocks based on different scan interval. All states per block are fetched in one request and is therefore more efficient than using the existing modbus integration.
Additionally a switch is provided to auto feed-in the power fed back to the grid to be able to heat up your water boiler with that energy instead.
Any suggestions or improvements are welcome. Please start a discussion or create a respective ticket in that repository.
So far I’ve created the first beta release and will now improve the quality by providing tests. I’m already using the integration with two askoheat+ devices connected.
