I would like to discuss if we want to carry on with the current approach of supporting different doors from a single esp-rfid. I think supporting multiple relays make sense for multiple doors in a same setting, but managing completely separate doors, like house door and garage door, for example, is a stretch of this project, I believe.
Especially if using integrations like Home Assistant, I believe that there should be one esp-rfid per "entrance". Each entrance could need multiple relays to be opened, but for different entrances, different esp-rfids should be used, and managed by a centralized system like Home Assistant or something else using MQTT.
In this way the roles and MQTT signalling can be simplified, as it's pointless to send multiple messages for a single entrance, or have different permissions. As it doesn't make sense to trigger a specific relay. It's either open or closed. Probably if the permissions are different you need to swipe a RFID card multiple times, use different PIN codes, or a combination of the two. So different esp-rfids are a better choice.
I think that this approach would be simpler on the esp-rfid, more secure, as you don't need relay wires going around, and more flexible as you can better manage access and permission for a single entrance.
What do you think? @omersiar, @nardev, or anyone else?
