Dampening

It strikes me as unworkable that forecast dampening be restricted to certain hours of the day.

In the height of Summer the curve looks way different to the depths of Winter.

Should dampening be based on sunrise/sunset times, and use a different algorithm than simply hours of the day? Possibly even account for shading coming from different directions at different times of year 🤷‍♂️.

I have built a mechanism that does a daily update of the dampening settings based on an hourly comparison of actual generation vs forecast over several previous days. That seems to take account of the changes in shading for my array, but I'm no HA/Python expert so have probably gone about it in a very sub optimal way!

Morning,

Thanks for sharing the additional info. Can confirm I've run into some issues with the Solcast dampening results, but not quite as described in #44 and #54.

On at least 3 occasions since I have set it up, Solcast seems to have crashed (seems but has not). ALL data points get set to 0. calling the API for an update does not reset it even though it is successful and even removing the Dampening settings doesn't reset it. The only way to get a forecast back that I have found is to restart HA.

Ive only been able to trigger the issue when Dampening is configured, and I was able to trigger it once simply by setting dampening configuration.

I'm going to back out the use of Dampening for the time being, as when the issue happens the knock on impact to battery charging etc is not ideal.

Example:
Happened at 00:03 (not a scheduled Forecast update time, 01:30 is the next update), but at the time the dampening values were updated via automation

All sensorts reported 0 (but now have a value as I restarted already today), example:

My dampening values:

at 00:03, those dampening values were updated by automation, which caused everything to fail. the dampening values are derrived values based on the time of day the sun comes up, thus update once per night

@Noodleyman - just noticed that @autoSteve has released 4.0.33 which includes the code reversion mentioned in the other discussion. I'd suggest downloading that to see if it has any impact.

[Nilogax]

@Noodleyman - see #60 for the 0.33 pre release info.

[Noodleyman]

ohhh, amazing. thank you! upgrading to that release now to see what happens.

More dampening goodness. #63.
