Hello everyone,
to save energy, I want to prioritize heating the hot tub when the photovoltaic system is supplying power. This is no problem with a potential-free switched socket, which I can control from my system. At the same time, I want to prevent the temperature from dropping below 36°C (96.8°F) if the photovoltaic system does not provide enough energy for an extended period. This could be done with a water temperature sensor that sends a potential-free signal when the set temperature is undershot.
The idea now is to use a socket with two potential-free switching contacts that enable power either when enough energy comes from the photovoltaic system or when the water temperature falls below 36°C (96.8°F). Overheating is prevented by the built-in control system of the hot tub. The power consumption of the hot tub is a pleasantly low 1400W. I have not yet measured the heat loss overnight during summer.
Using another potential-free switch, I activate the heating element in the domestic hot water heat pump. This raises the temperature in the storage tank by up to 10K to 63°C (145.4°F) (alternatively, the heat pump can be set to a lower maximum value). In this setup, the hot tub would have priority over the domestic hot water heat pump.
What do you think of this idea? Who knows of a suitable socket? Does anyone have a better idea?

Well, I don’t know of any Shellys with LAN – unfortunately! Otherwise, they’re very neat devices that even beginners can set up in minutes.
We all trust that you can handle the control as described above 😎 but you are moving quite far away from the KISS principle. If something goes wrong, you’ll have to troubleshoot in many areas. I’m involved here because I plan something similar but with 15m³ (530 ft³) of water 🙄
