Utility Meter kWh Readings Way Off in Energy Panel

Configuration
1

I have a SDR reading my 915mHz electric provider’s meter and publishing to my MQTT broker that I can use for a sensor in HA. I have the sensor added to the Energy Lovelace panel, but the kWh readings are waaaay inflated, which makes me wonder if there something I’m missing. There’s no way in less than 24 hours we’ve consumed 4400kWh of electricity!

Does anyone have any advice on “calibrating” this value?

Looks like your meter is not sending kWh, but Wh…

Is that as simple as changing my config.yaml to Wh, or do I need to do some napkin math somewhere else to convert the units?

I’ll test changing the unit_of_measurement to Wh in the meantime.

Thank you for replying.

You should be good with changing it, the napkin math is done already in the meter.
