EMHASS: An Energy Management for Home Assistant

Also I can see my forcast can bee way off from time to time. Not sure what I can check here?

You could set your MPC interval to run every six or twelve hours if you need your hot water to run that often, if you limit your prediction horizon then your hot water will then be scheduled for the optimal time every six or twelve hours.

The other approach you could adopt is to increase your running hours based on how long since your hot water was last run, eg if less than 6 hours since last run make run hours zero, if 12 hours since last run make run hours 2, if 24 hours since last run make run hours 12 hours. Your hot water thermostat will only run until your set point is reached so it won’t actually run for 12 hours.

Your solar forecast doesn’t require high accuracy to support a valid optimisation, so it shouldn’t be a big issue.

You can always supply an alternative solar forecast the same way you provide your Nordpool forecasts.

OK. Vill just return to next day optimization then. thanks.

But how can I then update this more often then?

torstein · February 13, 2023, 12:38pm

Problem is if i update 23.57 it only last for 24 hours and if price i very expensive next day 24:00 its better to change before 24:00. And if i do it 15:00 i do not get pv forcast for both days.

anybody know whats wrong?

Hi, I don’t know your configuration but it seems that you are trying to use a custom url to access the webui. This does not works and I’m currently trying to set the webui directly in HA using ingress. So just keep the url and token parameters to empty and access to webui using the localhost or the local IP address of your device at port 5000

nixtagangsta · February 15, 2023, 10:25pm

Hi thx for your answer.
I’ve set the url and token to empty but still doesn’t work

davidusb · February 16, 2023, 6:28am

Oh sorry I wasn’t clear, it should be the string “empty” for both parameters.

nixtagangsta · February 16, 2023, 7:28am

Hi

Tried that but still doesn’t work
Ran the curl command. With errors

davidusb · February 16, 2023, 8:08am

Ok, then share more information about your install type, architecture, configuration, etc.
Is the add-on running and started without error messages? Are you able to see the webui at localhost:5000? This was your initial question…

nixtagangsta · February 16, 2023, 8:20am

Running on rpi4
Starts up with no errors. Only errors is the ones attached here.

I am not able to see the webgui at all get error in chrome ERR_connection_refused

Could it be something with the weserver?

davidusb · February 16, 2023, 8:36am

Try:

http://<your_rpi4_ip_address>:5000

nixtagangsta · February 16, 2023, 8:54am

Doesn’t work

theailer · February 16, 2023, 10:50am

Checked this?

nixtagangsta · February 16, 2023, 11:06am

Yes set to 5000

davidusb · February 16, 2023, 11:52am

Any other app or add-on running at port 5000?

nixtagangsta · February 16, 2023, 12:04pm

Nope. Tried to set another port. Same error

markpurcell · February 16, 2023, 9:40pm

Might be worth going back to the start.
