What could be wrong here?

It seems that the add-on installation process just did not went fine for you.
Uninstall the EMHASS Add-on entirely and then reinstall the EMHASS Add-on from the store.

ralfna · January 8, 2026, 1:53pm

Hi David, yes now I setup to 9 days, which is working fine. If I increase any number will do 9 days. So I looked into the history of the sensor in HA and what I see is that after 9 days the history is going into a less detailed mode. To explain see picture:

Maybe that is my problem?
br Ralf

RikBast · January 8, 2026, 2:19pm

Solved it! thx

nikla · January 8, 2026, 7:14pm

Thanks David! Sorry for being clumsy. Now it works for me.
However, using KNeighborsRegressor and only 28 days of data I get R2 = -0.4414348682766347 so I think I need to wait a bit more before I use the training.

RikBast · January 11, 2026, 11:58am

Hi All,

Just a general question about best hardware for HAOS and EMHASS. I am now using a MacMini M1 8Gb running VirtualBox as VM to run HAOS. With 3 days of prediction+thermal model clearly the Mac mini M1 8Gb falls short. Is there hardware you can recommend? MacMini M4 24Gb? Or go for some mini PC, but which one? Linux based seems to be the best way to go. Just wondering what you guys use here. thx

What is everyone using for optimization_time_step with Amber?

I currently have:

optimization_time_step: 5
delta_forecast_daily: 1
prediction_horizon: 288

The problem is that it generates too much data and HA is unable to store it:

2026-01-12 09:40:05.216 WARNING (Recorder) [homeassistant.components.recorder.db_schema] State attributes for sensor.p_pv_forecast exceed maximum size of 16384 bytes. This can cause database performance issues; Attributes will not be stored
...

Any suggestions?

Using the Add-On and I’m trying out the new thermal_battery.
Unfortunately with no success yet.
This is the rest_command inside my configuration.yaml in HA:

emhass_thermal_battery_optim:

            }
           },
          {},
          {},
          {}
        ]
      }

Can someone help me out here. It’s not producing any useful output. I have three deferrable loads. Is the syntax inside def_load_config correct??
All other values are taken from the UI, right?

davidusb · January 13, 2026, 9:21pm

What do you mean by “useful output”? What does the logs says?
Check that your sensor “sensor.ecodan_heatpump_z1_feed_temp” does not have values below 20°C, otherwise this results in unfeasible optimization. Check that your start_temperature is already within the bounds.
Provide more context on your config to help

ulfish · January 13, 2026, 9:43pm

Basically all def_loads are zero.

And here’s the output:

Maybe your parameters are leading to an “Optimal” solution of doing nothing.
From your config this is normal for loads 2, 3 and 4 since you set operating_hours_of_each_deferrable_load for those to 0.
Now for the thermal load, maybe increase your min_temperatures to be higher than your start_temperature to force heating. Your 110m2 area is correct or a typo?

A new version has been released!

In this version there are a lots of improvements to the code reliability and maintainability.

There is one new feature that tries to greatly simplify the setup of the PV installation, now we can select PV module and inverter models by approximate power rating in addition to explicit database names. The code will automatically search an existent model in the database that matches the given nominal power.

Also reorganized and gave a new look to the documentation!

In the meantime I was exactly looking at operating_hours_of_each_deferrable_load. I erased all the 0…now I’m unable to view the config as code in the UI…just no reaction.
And the operating_hours_of_each_deferrable_load is not visible anymore

soco · January 14, 2026, 6:04am

Can you share the debug logs. These should include the information, if the thermal battery load is correctly detected.

ulfish · January 14, 2026, 6:45am

Thanks for your help. I will post them.
But first I need to get my UI working again. It seems that I can’t make any changes there anymore. It’s just not reacting to any changes. So, no save possible, deferrable loads settings are incomplete.
I would like to get into the “code-mode”

to set the 0’s again for ‘operating_hours_of_each_deferrable_load’ but that’s also not possible. I kind of crashed the configuration page.

Following the latest update I see this in the log


[2026-01-14 23:30:07,165] WARNING in retrieve_hass: Unable to find all the sensors in sensor_replace_zero parameter
[2026-01-14 23:30:07,165] WARNING in retrieve_hass: Confirm sure all sensors in sensor_replace_zero are sensor_power_photovoltaics and/or sensor_power_load_no_var_loads

I didn’t change the setup page and the sensor names are correct and exactly the same as before.
Anybody else?

In addition I also see (unsure whether related to the latest release):

The def_load_config for thermal_battery and thermal_config is only available with the MPC calls. The day ahead ignores these configurations.

Can you share your configuration?

Did you update EMHASS at 14.01.25 23:25:35? This error indicates, that something (the supervisor or you) stopped the add-on. The following four lines are normal output and don’t indicate any error.

Why??
Is it due to the nature of the model or has it just not yet been implemented for day_ahead?
