Oh sorry. I meant my own "5 in 1" is 30' away. I only have the one outdoor unit: a "5 in 1".
I thought the bridge would hear the sensor no matter what frequency I used-- since the bridge has no way of discriminating (there is no "A B C" switch on the bridge).
It's OK, Everything works. I was just curious about the readings.
Thanks for all the replies!
Changing channels means nothing to the bridge. It just passes on what it hears (or more accurately, decodes) . All data is sent on the same frequency.
The A-B-C switch just changes something in the data packet. As far as I can tell, the bridge doesn't decode that info as part of the information sent to MBW, but I suppose it could be mashed in there somehow that I haven't noticed (perhaps part of the sensor ID?)
