Error in log : grid currents invalid syntax #18186

Describe the bug

Hello everyone,

For a few days now, I've been faced with a recurring error message in EVCC logs that caught my attention. The line in the log is as follow :

[site ] ERROR 2025/01/12 13:03:20 grid currents: strconv.ParseFloat: parsing "": invalid syntax

From the error message, I think it's related to the site configuration. However using the trace I can't pinpoint where to look.

Steps to reproduce

Just turn on EVCC, the error message appears every 1 mins approximately.

Here's what I've done so far.

Make sure my Envoy device is functionnal. I can access the web UI and the app to see real-time production.
Make sure my Envoy token is valid. I can use the token to login into the web UI.
Make sure that the services I use for my cars are fonctionnal. Teslamate, my ble proxy and the proxy for the wall connectors are all working as expected.

I'm a bit lost, since I truly don't know where to look. Any help on that regard would be greatly appreciated.

VolkerK62 · 2025-01-12T12:34:15Z

you have a 1-phase system?
With 132.1. there was a change regarding currents. #17193

Please try, if 132.0 is working.

MrBLJ · 2025-01-12T12:49:35Z

Thanks a lot for your quick answer. i'm indeed using 0.132.1 (sorry for the typo in the OP I'll fix that). I'll try downgrading to 0.132.0.

I'm indeed using a 1-phase system.
