EMHASS: An Energy Management for Home Assistant










If you use Frigate the webserver uses tcp port 5000.

Nope. No frigate.
Thx for info

Hi - I am having an awkward problem when doing MPC calls with current values (beta > 0):
Current data for P_Load is always properly working but current data for PV (P_PV) sometimes uses correct data and sometimes just uses 0 despite the underlying sensor being >0.

Below some screen shots showing what I am mean when doing an MPC call every minute (same problem when doing every 15 or 30 minutes) with beta = 1 and alpha = 0.

Power no var Loads = power sensor in W for actual consumption that is fed to Emhass
Load Power Forecast = Published Data from Emhass (P_Load)
Solar Power in Watt = Current PV Production (data coming from Powerwall) that is fed to Emhass
PV Power Forecast = Published Data from Emhass (P_PV)

There is not missing data in ‘Solar Power in Watt’ but Emhass seems to struggle and shows 0 every 30 min (sometimes just for 1 min, sometimes for 30min).

Logs in Emhass look normal. Extract also below.

Any ideas what’s happening? Can I somehow debug?
I have no problem when using alpha = 1 and beta = 0 (i.e. just planned data that I feed with the Emhass call).

Log from around 11am (you can see the change in in P_PV and cost function when the wrong current PV data is used but otherwise no changes):

Thanks

I have recently been seeing something similar with beta=1, initially it was for just a minute, but then I started seeing it spread out to 30 minutes as you are reporting.

My theory is with beta=1 is that it is looking at the values for 24 hours past and if there is a glitch = zero that gets amplified and repeated over and over.

I now running with alpha=1,beta=0 and supplying the now values directly on the command line, I now see agreement between EMHASS forecasts correct to the W every minute.

I also had to supply the current/now load forecast on the command line and created a FIFO buffer to track the past 24 hrs load_no_vars.

          \"pv_power_forecast\":{{[states('sensor.APF_Generation_Entity')|int(0)] 
           + state_attr('sensor.solcast_forecast_today', 'detailedForecast')|selectattr('period_start','gt',utcnow())
             | map(attribute='pv_estimate')|map('multiply',2000)|map('int')|list 
           + state_attr('sensor.solcast_forecast_tomorrow', 'detailedForecast')|selectattr('period_start','gt',utcnow())
             | map(attribute='pv_estimate')|map('multiply',2000)|map('int')|list
          }},

          \"load_power_forecast\":{{
          [states('sensor.power_load_no_var_loads')|int] +(states('input_text.fi_fo_buffer').split(', ')|map('multiply',1000)|map('int')|list)[1:]
          }},

Understood and makes sense. Would you mind sharing your FIFO buffer code? Still wondering on implementation. Thanks a lot!

No problem.

I store input_text.fi_fo_buffer as a list of 48x kW values for each 30 minute time slot. I chose kW as it would fit inside the 255 char limit.

Every 30 minutes I reset the input_text.fi_fo_buffer with elements [1:48] + the current value of power_load_no_var_loads. It might be more accurate to use the rolling 30 minute value, but I haven’t implemented that.

I have setup the fifo using helpers:

and you need to prefill with 48 values, one neat benefit is you can change the prefil at any time, if for example your forecast household load changes.

trying to understand the soc of battery and not understanding why its moving up and down all the time?


I think i figured it out. It had a parameter with all solar to grid activated. But I have another question as well. 13:00 are there lots of solar power coming in and the forcast soc is 90. If i run an automation and set the soc to 90 on my inverters it will charge from the grid if there is no solar. Not always this is profitable. Or do you do this in another way?

So in that same automation or in a new one, stop the battery charging when it arrives to SOCmax. I don’t see the problem since you said that you have lots of PV in that time slot. Or simpler set the automation to directly forbidden charging your battery from the grid. EHMASS is just giving you an optimal SOC reference to follow, but you need to fine control that using automations

Yes. Only that if its set to 90 the battery will not compensate if there is not enough solar for a period. Yes i will find a way todo this :blush:

What is the difference between cost. Self consumption and profit?

Hey

Back from Austria.
Reinstalled emhass now I can reach the first page in my browser. But, when clicking one of the options nothing happens.

I couldn’t find my solar module so I picked a longi panel.
My panel: Denim U - Mono 405 All Black Half Cut

In the string of your module you have to replace all the special characters in the model name by ‘_’.

Thx. Do you know if denim exists in cec list?

Changed the namn

If you have the optimization results graphs then everything is ok. Those errors werer thrown because you tried to publish data before performing the optimization task, so there was nothing to publish.

Ok. But I don’t see any graphs

Hi
Can someone help me?

I can reache the emhass website but it won’t display any graphs?

Hi,

as I’m using apex charts (as presented by @markpurcell ) to show EMHASS data in Home Assistant:
Is there a way to get unit_load_cost and unit_prod_price as sensors in Home Assistant? Currently I have the standard sensors like those for defferable nodes.
As I’m generating the array of prices in Node-Red, creating a sensor with attributes via Node-Red might result in different formats how they (or timestamps) are saved compared to getting them from EMHASS which would be very convenient.

Thanks!
