Re: [weewx-user] Add Solar Generation to WeeWX

Thu, 12 Mar 2026 08:28:40 -0700

I have done something very similar to this by using SolarAssistant which polls my inverter every 5sec. SolarAssistant has a built-in broker which I subscribe to and inject the data into my WeeWX loop stream. From there I can display the live data on my WeeWX dashboard also archive to the database. From there Cheetah is generating a json data series to display  charts and an energy dashboard. It looks like you almost there as you are already receiving air quality data from HomeAssistant via MQTT.

You can see this happening on the link below.

I have solar, no storage, and would like to see the solar generation data in WeeWX.
The install uses Envoy for metering and I have the data going into Home Assistant via their API. I have some other sensors attached to HA and have those feeding CO2 and PM 2.5 to weewx via MQTT currently.

 Primarily, out of the 20+ data points, I'd only like to display current solar production, current consumption, current net consumption (utility - solar).

I don't really see a need to store the data.
Should I extend the schema, add a solar database, or repurpose unused existing database fields?

Thanks for any ideas
