Hi,
The MQTT binary sensor trigger the group switch if included into the group. If there is a PIR, it will trigger the room switch each time the PIR sensor detect something. The group switch doesn’t trigger the binary sensor, this is the good part.
The bad is if one binary sensor is active, the group switch is ON and you cannot switch it off, so you loose the command over the group.
I think the (binary)sensor shouldn’t trigger the group.
Please advice here. Should I report it as a bug to be solved in the future or this is the desired behaviour and the users must group sensors and relays in different groups? Thank you.
