I see the following error message in the log after clicking "Optimise" in the web interface:

Please share your configuration to be able to provide a solution. You have a problem retrieving data from HA, this is typically a failed configuration.

Yes.

Change the value of these two parameters:

andreas-bulling commented 9 months ago

I have removed them before posting here - they contain valid/correct values.

UPDATE: I just created a new token to make sure. Same error message.

andreas-bulling commented 9 months ago

What I find strange - I don't have a sensor called sensor.ac_loads_positive. Also not configured in EMHASS. Why does it try to read that out?

davidusb-geek commented 9 months ago

I have removed them before posting here - they contain valid/correct values.

UPDATE: I just created a new token to make sure. Same error message.

Please just follow the solution that I gave in my previous post. No need to create any token. You need to write the word "empty" on the url and token parameters. That's all

andreas-bulling commented 9 months ago

Oh dear, that was an easy fix. Thanks a lot!

Hi sometimes there is a bunch of unreadable error traceback from Python. But we should focus on the log error from EMHASS. The messages are quite explicit here:

2024-02-08 08:27:26,300 - web_server - INFO - Retrieving data from hass for load forecast using method = mlforecaster
2024-02-08 08:27:26,301 - web_server - INFO - Retrieve hass get data method initiated...

...please run a model fit method before this predict method...

davidusb-geek commented 9 months ago

If you want to use the machine learning model then you have to train it first to create the trained object. Then you can use the predict method...

andreas-bulling commented 9 months ago

I have tried that - that's the second half of the log output, starting from 2024-02-08 08:27:46,777 - web_server - ERROR - Exception on /action/forecast-model-fit [POST]

davidusb-geek commented 9 months ago

Ok then you just don't have enough history data. By the default the system try to retrieve 9 days of data but if you have not configured that in your HA recorder then we are not able to fetch the data. Change your recorder configuration to retain much more data, wait for the database to fill and then retry. Or you can change how many days you want to retrieve, here is the documentation: https://emhass.readthedocs.io/en/latest/mlforecaster.html#a-basic-model-fit

But less days is not a good idea to obtain meaningful forecast results with this method.

andreas-bulling commented 9 months ago

Thanks, have done that and will see how it goes in a few days. Strangely enough - the option was not modified by me, i.e. it was at the default setting. If 9 days are required but the default in HA is shorter this probably should be added to the documentation...

andreas-bulling commented 9 months ago

One thing I find confusing: The default for historic_days_to_retrieve is two days. Or are these two different parameters?

davidusb-geek commented 9 months ago

That link in my last post explain this ML Forecaster. The documentation explains that the default number of days to retrieve is 9 and it clearly states that this method should be provided with as much data as possible an that you need to configure your HA recorder to do that. It is in the docs.

One thing I find confusing: The default for historic_days_to_retrieve is two days. Or are these two different parameters?

Two different parameters. That one in the configuration pane is for optimization based on past history data. This one defaulting to 9 days is to train a machine learning model for load power forecast.

andreas-bulling commented 8 months ago

Problem never got solved for me. I gave up.
