It should be doable. I do something similar with a few temperature sensors/fields. The fact that you are dealing with string data does add some complexity. First, for the field configuration you will need to set the conversion_type = None. Although it is not documented on the wiki, see https://github.com/bellrichm/WeeWX-MQTTSubscribe/wiki/Configuring#conversion_type This will stop MQTTSubscribe from trying to convert the incoming data.
Next, you will need to configure the accumulator for this field/type. See, https://github.com/weewx/weewx/wiki/Accumulators. It looks like for this field/type you want to set accumulator = firstlast and extractor = last. Now you should be able to access it via $current. field/type name. If you get this working, I’d like to ‘steal’ the details/steps for a wiki page. -rich On Sunday, 7 February 2021 at 17:05:51 UTC-5 Tarmo wrote: > Can I do it?
