Remark:
It is not recommended to use a 230V relay because this type of relay with a center contact between the coil supply pins does not meet the mandatory 4kV surge protection.
The need to register the control software and the specific boardrelates via a shared password to the home WiFi on the manufacturer's server.

The product is not a separately functional unit, it requires professional assembly.
