Set states for all devices with switch 0?

[Achronite]

For OOK control only devices it is possible to use switch '0' to turn all switches in the zone to be ON or OFF.

This issue is to find a solution for the return MQTT topics for this.

Options:

1. Set MQTT state topics for all switches 1-6 with ON or OFF
2. Only set topics for switch 0 and let user deal with it (the current solution).

Thoughts anyone?
