I have a pool pump (Badu Eco Touch Pro II) that supports three speed settings (+ off) and can be switched via a potential-free contact. I’m currently using a timer supplied by the manufacturer, but I’d also like to control it remotely and automatically when there’s a surplus of solar power.

A friend of mine is an electrician and has recommended installing two Shelly Pro 2 units, with each Shelly Pro 2 controlling two speed settings.

Do you think this is the right approach? Can I configure the two units so that they can be operated as a single unit – particularly when programming switching times? After all, only one of the four switching states can be active at any one time.

Thanks for any tips and advice
