Graph not updating.

[Coffeeman666]

After various updates my Tibber Custom graph no longger updates. Tried to reinstall Tibber Custom a couple of times. And also tried to delete the graph manually. Resulting in no graph at all. It no longer saves the .png file. Anyone else with this problem?

It stopped updating the graph some days ago. I had updated both HA and the tibber_custom the day before I noticed it. Have not done any further testing to try to make it work.

I have a similar problem. Graph is not updating and I can't find any errors in the logs. It has been like this for a while now, maybe two weeks

I encounter this aswell. I have removed integration completely and "installed" it again. Everything looks okej but no png is created. And no errors in the logs either. Even tried to use my postalcode instead of streetname since my contains the swedish "ö". Just to exclude that as a failure possible.

I removed the exception handling around the "save" part of the image generation function. The exception handling is only set to print its errors if debugging is turned on, should probably be a _LOGGER.critical..

Anyways, without the exception handling I get the following error message which shows why this fails:

TypeError: async_add_executor_job() got an unexpected keyword argument 'dpi'

Removing dpi=200 from this function solves the issue for me. Not quite sure why this fails tho.. Cant reproduce it locally with matplotlib.

[espenfjo]

Removing dpi=200 from the call to await self.hass.async_add_executor_job(fig.savefig, self._path, dpi=200) should be safe since fig already have dpi=200 set: fig = plt.figure(figsize=(1200 / 200, 700 / 200), dpi=200).

@espenfjo thank you for the finding. Much appreciated.

[Coffeeman666]

Nice finding. Now it works like a charm again. Thanks!
