ExtraTemp1 as Outside Temperature

[Søren Helskov]

Hi 

I have this TE923 weatherstation that has been running with Weewx for almost 

7 years now.
My problem is that on Channel 1 on my weather station, i have some strange sensor reporting in, with wrong value and overwriting my local sensor. I think it could be my neighbours weather station of same brand. 
I have now changed my outdoor sensor to channel 2. 
But in weewx it results in i now have Outside Temperature with wrong value and a new measurement called Temperature 1. 

I dont want to rename Temperature 1 to Outside as i have 7 years of log data on the Outside Temperature. So i would like to switch, so the Channel 1 is Temperature 1 and Channel 2 is outside Temperature. 
I have tried to look in weewx.conf but its only labels. 

Hope someone can help my.

I Would like to Map t_2 to Outside Temperature

Where are all these mapped?

In the directory /usr/share/weewx/weewx/drivers you should find the file te923.py. From line 473 you will find the mappings starting with DEFAULT_MAP = {
...
    'outTemp': 't_1',
    'outHumidity': 'h_1',
    'extraTemp1': 't_2',
    'extraHumidity1': 'h_2',


by:
    'outTemp': 't_2',
    'outHumidity': 'h_2',
# 'extraTemp1': 't_2',
# 'extraHumid1': 'h_2',

replace.

Please make a copy of te923.py before editing.

Hi Thanks Michael

Was really helpful and solved my problem.

I was really looking in the documentation here

https://www.weewx.com/ 
but found nothing. :(

Best Regards.

you can do this in the weewx configuration file using the 'sensor_map' in the TE923 section.

the default sensor map looks like this (you should see this in your weewx configuration file, but it is probably commented, since it is the default behavior):

[TE923]

    ...

    [[sensor_map]]

        windLinkStatus = link_wind

        windBatteryStatus = bat_wind

        rainLinkStatus = link_rain

        rainBatteryStatus = bat_rain

        uvLinkStatus = link_uv

        uvBatteryStatus = bat_uv

        inTemp = t_in

        inHumidity = h_in

        outTemp = t_1

        outHumidity = h_1

        outTempBatteryStatus = bat_1

        outLinkStatus = link_1

        extraTemp1 = t_2

        extraHumid1 = h_2

        extraBatteryStatus1 = bat_2

        extraLinkStatus1 = link_2

        extraTemp2 = t_3

        extraHumid2 = h_3

        extraBatteryStatus2 = bat_3

        extraLinkStatus2 = link_3

        extraTemp3 = t_4

        extraHumid3 = h_4

        extraBatteryStatus3 = bat_4

        extraLinkStatus3 = link_4

        extraTemp4 = t_5

        extraHumid4 = h_5

        extraBatteryStatus4 = bat_5

        extraLinkStatus4 = link_5

to change the sensor mapping, uncomment the entire sensor map, or, if it is not yet in your weewx configuration, paste it into the TE923 section.  you must specify the entire sensor map, not just a single item.

then, to swap channel 1 and channel 2, change this:

        outTemp = t_1

        outHumidity = h_1

        outTempBatteryStatus = bat_1

        outLinkStatus = link_1

        extraTemp1 = t_2

        extraHumid1 = h_2

        extraBatteryStatus1 = bat_2

        extraLinkStatus1 = link_2

to this:

        outTemp = t_2

        outHumidity = h_2

        outTempBatteryStatus = bat_2

        outLinkStatus = link_2

        extraTemp1 = t_1

        extraHumid1 = h_1

        extraBatteryStatus1 = bat_1

        extraLinkStatus1 = link_1

by changing the configuration file, your changes will persist even when you update/upgrade weewx.

and be sure that your neighbor does not also use channel 2!
