The P1 port of your digital meter may be used as an information source for smart controls, but according to Belgian law, it cannot serve a security function.
Make sure that your device has the CE marking which shows that your device has been evaluated and meets European standards regarding safety, health, and environmental protection.
If in doubt, consult an installer to check whether the circuit of the socket where you plug in the installation can handle the load and whether it is safe to use your device.
Consult your Owners' Association (VME, for apartment buildings), city or municipality to see if there are additional regulations. In some cases, they may impose restrictions on the use of plug-and-play devices.
