bridge hijacks regular 433 traffik?

[gurkburk76]

So i have of sensors paired up with a telldus bridge that works well, but it seems like this traffik stops working when i connect my modified sonoff 2.2 board with this firmware on it.

Details:
i got a few nexa smoke detectors and wanted some way of catching trafik if/when they go off so i got a sonoff board, modded it wand flashed this fw on it, works well.
Except for the fact above, my normal 433 trafik from/to my other 433 sensors to and from my telldus bridge seem to get blocked when my sonoff device is turned on.

Why is this happening?
Can i do something about it? I'de rather just have the telldus stick handle whatever i have paired to it and overwatch the traffic for the smoke alarms with the sonoff.
