Just a caveat: be careful, even if you succeed in the installation, a Pi 3b may not be enough to properly run EMHASS. When I started I ran it as a HAOS add-on on a Pi4 and it had serious performance issues.
Anybody here using Solax equipment?
Yes, you can change your optimization time step to 15 minutes. Same in NL, however for the time being there will be no price difference within the hour - will be a matter of time so good to prep.
Looks great, for consideration: multiple price sensors would be great, at least for selling and buying but probably also as a fall back (eg. entso-e has been acting up a few times this month⌠good to fall over to a second provider).
mpc optimizer started giving me âInfeasibleâ. Anyone here that can point me in the right direction how to find out why? I know I pass a lot of runtime parameters but that is because I set them (deferable load info and bettery settings etc) from the lovelace ui or trough auttomation (input_number or input_select in home assistant).
The resulting parameters being passed to the naive-mpc-optim api call you can see in the log below.
load cost forecast, prod_price_forecast and pv_power_forecast all seem fine. I use a prediction horizon of max 24hrs depending on how many hours of load_cost_forecast I have available. Next day prices typicaly arrive around 1pm, so worst case prediction horizon is 24 (12 hours).

@davidusb , I think I found a small bug by the way. I have âsensor_power_load_no_var_loadsâ set as âsensor.sec_pac_non_deferableâ in the emhass config. But if I donât pass my sensor name as the âvar_modelâ runtime parameter to the forecast-model-fit api call I get an error that my, non existing, sensor.power_load_no_var_loads has no data
´´´
ERROR - web_server - The retrieved JSON is empty, A sensor:sensor.power_load_no_var_loads may have 0 days of history, passed sensor may not be correct, or days to retrieve is set too heigh
´´´
Probably everybody uses the default sensor.power_load_no_var_loads
I think your SoC is currently below the minimum. EMHASS doesnât like that. Charge your battery or lower the minimum for a bit.

Hi all,
Since the last update I have some problems with EMHASS. Its seems to do nothing anymore, I got the following logs:

Same. Iâve long been running EMHASS on 5001 and itâs worked fine, but the latest update has broken something there.
The docker run command is running EMHASS correctly on 5001, and the UI is accessible on 5001, itâs like EMHASS itself doesnât know its on TCP/5001 more than anything else. Shell-Commands have always been on 5001 and worked ok (nothing changed with those).
Have been doing a few restarts in the logs as well trying a few things.

Hi
Whenever I try to run a optimization task EMHASS crashes:

Thanks guys, 0.12.4 is better (it runs now). Itâs started throwing these python errors however where it didnât used to, hitting the publish-data API endpoint.

Iâve finally managed to get my EV charging setup working with both departure time and maximum price constraints. Itâs not perfect, but it works! A big thank you to everyone in this threadâIâve incorporated many ideas and snippets of code from several of you.

Great work on your car charger schedule.
There are some subtle issues with get the end_timestep correct.
Can you share your code please?
Absolutely, but as I wrote earlier, there are still some small bugs. Most of the things are based on the packageâs files.

My EMHASS runs as a docker standalone.
When I try to start version 0.12.4, I get the following error message:
Attaching to emhass
emhass | error: Failed to spawn: gunicorn
emhass | Caused by: No such file or directory (os error 2)
emhass exited with code 0
image: Package emhass ¡ GitHub
Version 0.12.2 works.
Sorry to hear this.
Please open a github issue so that it can be treated.
I try to find the best setting according my demands. I want to use as much as possible own produced electricity and when production is low as now, I want to load battery from the grid and use it when the price is higer for 1 unit (SEK) the bought. I have tried âself consumptionâ, but it doesnât work as planned. It want to buy for 2,11 and sale for 2,47. Beside this it plan SOC 0% although min SOC is 10 %. Should I change to cost instead? Or maybe change âweight_battery_dischargeâ?

According to that table it is actually buying from the grid when its less expensive, so 2.11 SEK and when its the most expensive 2.47 is actually just discharging the battery to supply your load with no grid import.
The SOC problem seems weird though, what is your SOCinit, it seems 0 ?
