Forecast not available

[garethmarlow]

Hi, big fan of this integration, have been building automations to minimise grid carbon when charging my home battery.

Last night (2023-10-19) at around 22:00 the integration went offline. The API is still available but poking around today I think the issue is caused because the API forecast currently extends to 22:00 this evening (2023-10-20).

Turning on debug logging:
2023-10-20 14:26:18.686 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Postcode setup: CB4 2023-10-20 14:26:18.686 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Coordinator refresh triggered 2023-10-20 14:26:18.686 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Coordinator update data async 2023-10-20 14:26:19.989 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Coordinator update done 2023-10-20 14:26:19.989 DEBUG (MainThread) [custom_components.carbon_intensity_uk] update_data carbonIntensity response is: {'carbonIntensity': 32, 'fossilFuelPercentage': None, 'forecast': None, 'lowCarbonPercentage': None, 'status': 'very low', 'optimalTo': None, 'optimalFrom': None} 2023-10-20 14:26:19.989 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Finished fetching carbon_intensity_uk data in 1.303 seconds (success: True) 2023-10-20 14:26:19.989 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Coordinator refresh completed

I will continue to poke around - and this may fix itself if the API forecast is fixed, but want to know if others are seeing this issue and whether there's a work around to get access to the partial forecast.

I have the same issue - just returned from a few days away and did some update catch up on HA versions .. after that I see "Failed setup - will retry" ... looking in the log I see:
'2023-10-20 15:50:40.788 DEBUG (MainThread) [custom_components.carbon_intensity_uk] Postcode setup: PO6'

I need to spend some time on this...

The API is still not reporting results beyond 10pm tonight:

https://api.carbonintensity.org.uk/regional/intensity/2023-10-20T17:00Z/fw48h/postcode/CB4

I was consistently getting the same result as you (Finished fetching carbon_intensity_uk data in 0.605 seconds (success: False)) but after many restarts of HA I'm getting (success: True) in the logs.

I have implemented a solution suggested by "Speak to the Geek"
https://www.speaktothegeek.co.uk/2023/05/local-uk-grid-carbon-intensity-in-home-assistant/ to just get the levels - seems to work fine. I am sure it could be adapted to pull the forecast as well

Cross Post.. yes.. the state for me is always unknown but the values are there

[garethmarlow]

...and the States tab in Developer Tools is also showing nothing...

[snigehere]

I see other values in your earlier picture are also unknown.. maybe worth restarting .. maybe just 'rest' functions... I had uninstall Friday and reinstalled today when I saw the api was back up.

I did also reach out to national grid and they said....
Thank you for your query.
The API went down over the weekend but it resumed on Sunday evening so it should all back up and running now, apologies for any inconvenience.

[garethmarlow]

Nice that you got a response! This integration's still not producing a forecast for me despite restarting everything under the sun. I don't have enough python knowledge to debug on the command line to see what the API calls are returning - but the jfparis version is working, and I just need the forecast rather than the other sensors so I'm back up and running again.

What do you see in the log now the api is available?

[garethmarlow]

I've uninstalled it now and those logs have cycled, but it wasn't throwing any errors in the log, just not extracting any data apart from the current period forecast.
