Re: [weewx-user] FYI: weectl fails to change ISS ID away from 1 on Davis Envoy

But now you have an easy workaround. Set the transmitter type for channel 3 to a temp_hum device.  Then remove ISS from channel 1 and add it as channel 2. Lastly, remove the temp_hum device on channel 3.

The right set of bits seem to be getting sent to the Envoy, yet it does not recognize the ISS. There's something I'm missing in the documentation. I'll keep plugging away at it. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
