Solcast Global Solar Power Forecast Integration

[rwbarrett (Roger)]

Found the solution on github - delete the solcast.json file in the config directory and reload the integration and it will spring back to life

[Jeza]

What did you find to change, i have this problem also?

[rwbarrett (Roger)]

also make sure you have set up an automation to trigger the forecast updates (as above in the thread) - the integration no longer does that itself

[MickW69 (Michael)]

I realy like the dampening function concept as the 2 hours before sunset are usually a bit lower than forcast. The time of 1-2 hours before sunset is going to change thoughout the year, so I’m not sure how to actually implement it.

[DrewP]

I need to remove the first part of the day from the forecast in winter due to shading, any idea how to add up the first x hours of the forecast for a day?

[noelie]

Hi there, first of all a very nice integration. Still kind of new to this, so sorry if this is a stupid question. Is there anyway of getting the estimated solar production in 2 hours, in 3 hours, etc. so that these are all separate sensor values? I would like to send these values to my Loxone automation server.

[Gav_in]

That’s all there (I think) in the attributes under Today’s forecast, so it’s available but if have to use Template Sensors or similar to surface the into your Dashboards…

I use this (prob borrowed from this thread) to show me half hourly forecast over next few days…its not separate sensors but works for me…

Wasn’t my Q originally but…wouldn’t that be just how to extract an attribute from a sensor, but not sure that’s what they’re asking…what I’d taken from we post was how to show forecast in X hours from now so it’s a little more involved I think (and even then doesn’t the forecast sensor here bundle the whole days hourly forecast into one attribute called DetailedHourly, or am I misunderstanding that)

[noelie]

Thanks, but not quite what I was looking for. In Gav_In’s next post he explains it better. I also think there might be more involved as I will also need to get the current time of the home assistant server, find the next hour in the file, then save that in the sensor value. I did see that the detailed forecast is done every 30 minutes, so ideally I would average the 2 values within that hour.
Any idea’s would be more than welcome.

Has anyone managed to create a bar chart of the forecasted values for the next 7 days? This was as good as I could get.

Thanks for that example, but I was hoping to get the y-axis to display the total value for the day rather than the individual 30 min values

[samourai47]

Hello
I uninstalled my solcast integration correctly from HACS, because i have a litte problem
i reboot, reinstal the last version
But when i want add in the integration panel it says me thats it is not possible
Only one session is permited…

I dont have the solcast.json file in /ha/config… to delete
Thank’s for your help

I post the same message in

Re install not possible · oziee/ha-solcast-solar · Discussion #274

Sorry

[samourai47]

Hello
I try hundred method for installl reilstal etct etc… but always the same results

I don’t know where the information could be modfied
If you have some idea
Thank’s

[AlexJ (Alexander Jacubowsky)]

Regrete fully des not possible to use the integration with two or more Accounts , so it is not possible to use it with more than one plant with two orientations.
