Heating and heat sources
A buffer tank, a gas boiler and a heater running on photovoltaic surplus work together, and four zones hold their target temperature. Change the whole-home mode, set the temperature and see how each source and each zone responds. This is a demonstration: the buttons work, but the panel is not connected to Home Assistant.

Want a heating panel like this in your home?
I design Home Assistant panels for heating with several heat sources: a buffer tank, a gas boiler, a heat pump and a heater running on photovoltaic surplus, with operating modes, a schedule and logic that keeps the sources in the right order.
