I am experiencing the same issue with the same tracebacks in the logs. Looking at the historical data it looks like it stopped collecting at around 3am on the 31st March for me.

Same for me also

In time honoured Internet fashion, me too!

After reloading the Integration I get the following in my logs. Has there been an API change?

Stopped working for me too

[Asus64UK]

Also stopped working here, same debug info.

[Meliden11]

I had the same issue, and this is what I did to resolve it.

The fork for this repo seems to have resolved the issue with regards to the out of range error, which seems to be an issue that already exists - https://github.com/root0x/ha-hildebrandglow-dcc/tree/main

• Looking at the new commits on the repo, the only file that's changed is the sensor.py file - https://github.com/root0x/ha-hildebrandglow-dcc/blob/main/custom_components/hildebrandglow_dcc/sensor.py
• Following the Manual installation steps on the README.md, I copied/pasted the contents to my local config/custom_components/hildebrandglow_dcc/sensor.py file
• Restarted HA, and it's working as expected.
• Hopefully that should get you up and running, until this issue has been fixed by this integration; that is if it gets fixed.

Please NOTE - do not copy/paste from a fork without knowing/understanding what the code that's been modified is doing.

As always, do your due diligence 😄

My hero! thanks!

[bsdnazz]

I've done the same - copied the sensor.py file - and it's working again.

[Asus64UK]

Thank you for the info, all working again.

[saleemkhalil]

Working for me but it's picking up incorrect prices from the bright app. I don't remember making any changes to the original integration to get this to work?

Working for me but it's picking up incorrect prices from the bright app. I don't remember making any changes to the original integration to get this to work?

I've got a similar price discrepancy. Looking at the day's electricity costs I have £3.35 via DCC API and £2.92 via a GD-1 and MQTT.

The ratio of £3.25 to £2.92 is 1.147 which is basically 1.15 or 15%. I wonder if VAT at 20% rather than 5% is being added.

[richardsg307]

Same with me. The last credible data point was around 01:30 on the 31 March 25.

Here's a History graph...

The Blue line is the Hildebrand data, the Yellow is from my own LED pulse counter.

I will study the above to see if I can fix it, but sounds like it's something external gone wrong. Or Hildebrand have made a change that the Integration needs to react to.

Edit: I checked the original (which I've only had for about a month) sensor.py file with the one now in Github and they are different. So I replaced it as instructed above, re-started HA and now I have credible data points for usage and cost. The rates look good still too.

Thanks
