Hi weewx friends,
I am currently using a separate windspeed and direction transmitter @ about
10 meters in my antenna tower. This transmitter powered by battery, that is
being loaded by the power of its small solarpanel in the housing.
This transmitter is configured as an extra ISS (type 4) on the Vantage-Vue
console. It would be nice if there was a possibility to monitor the
current battery status of this extra Windspeed meter transmitter
Because it is in principle the exact same device as the main ISS
transmitter, I think it should be possible..
I have tried to add an extra parameter (windBatteryStatus) in the loop of
the file vantage.py : ('txBatteryStatus', 'B'), ('consBatteryVoltage',
'H'), ('windBatteryStatus', 'B'), and in
self.loop_data = {'txBatteryStatus': None,
'consBatteryVoltage': None,
'windBatteryStatus': None}
I also added this parameter in skin.conf, but that is not working... I
get this errormessage in the user.log:
engine: Caught unrecoverable exception in engine: ***

**** data_tuple = loop_fmt.unpack(raw_loop_string)

**** Exiting.
(I have restored to the original vantage.py)
Has anyone an idea how to achieve this ?
Thanks!
