DSMR Smart Meter suddenly doesn't show energy consumption anymore

Energy

Since November 2024, I’ve successfully connected a Sparky P1 meter to my Home Assistant system using the DSMR Smart Meter integration.

All consumption data was properly displayed in my Home Assistant ‘energy dashboard’ until mid-afternoon on January 6th.

Since then, no electricity or gas consumption data has been received by Home Assistant. All DSMR entities are listed as Unavailable.

My Sparky’s IP address remains unchanged, and the Sparky app itself displays the consumption correctly.

What could be the cause of this sudden problem with the Home Assistant connection?

I think the automatic update of Supervisor to version 2026.01.0 may have caused this.

Anyone else having the same issue?

For me it stopped working after jan 8 16:55
I did update the HA core that morning to the newest version.
Reverting back to the backup from before the update did not help.
I’ve got a mail from Chargee stating something is stuck and they are busy fixing it.

For me it stopped working two days ago as well after no intentional updates to HA. Sparky app is working perfectly but no data in HA. Tried removing and adding the DSMR Smart Meter integration again but now I’m no longer able to connect to the Sparky P1 dongle…

Happy to learn more once a fix is available

This issue turns out to be a result of a firmware update of the Sparky device.
Supplier Chargee is aware of the problem and they are currently working on a fix.

Problem fixed by supplier by pushing a new firmware update to the Sparky. :+1:
