I have running at home a REMKO Heatpump WKF-Compact. There is currently no integration for Home Assistant. So I have created a very basic integration. It read a few sensors. Also, you can modify settings using the rest_commands.
I have a few specific cases I want to switch to standby the heating/cooling mode. For example, in case a door has been opened for a certain time or the energy price is very expensive at a given moment.
So I have shared my code so you can create a similar dashboard like below:
Hi Jo.
Thanks for doing lots of excellent work. I had been looking for a REMKO integration for a while.
I have installed the files from Github and with some tweaks got it to work.
At first it gave errors, but I seem to have resolved them now.
Had to rename the folder to remko_heatpump (and not remko_heat_pump), as on Github
Had to modify init.py and remko.py to include a ā.ā before const
Had to modify sensor.py to include ā.ā before āremkoā and āconstā
In const.py had to change to;
DOMAIN: str = āremko_heatpumpā
BASE_API_URL: str = āhttp://xxx.xxx.xx.xxā
Now the sensors show up nicely.
I would like to also control the heat-pump with some commands, but here it gets a bit technical?
How did you get to your Status of DHW and Heating toggle-buttons in the dashboard? Did you make several rest commands that you call? And how do you transfer the status with the command?
Many thanks
Rolf
I am also quite interested where you got the code table from, there are some commands Iād like to give to the WKF as well, like do a SWW (party mode).
Thanks in advance!
Cool you are using my code! It was a struggle to have it working. Also good feedback on the fixes I will update this in the repro. I have also a newer version running myself not that much changes but more or less optimizations. I will update this in the repo.
About the toggel switches I have created rest_commands for this. I will share examples in the repo for this.
Last week I have changes a bit on turning on and off for cooling and heating per floor. I figured out the honywell zone manager I have takes up quit a bit of power when the valves are open.
I have found the codes by reverse engineering the cgi api on the remko interface. I have created the tables from this information. Remko.de does not give any help on this probably the even donāf understand what we are doing.
I donāt understand what the sww party mode is but I know and can find the codes for you. I will publish this also in the update.
Okay, I have updated the repo. Small fixes. The only thing I have changed is the PowerConsumptionSensor so you can create a power consumption item on your energy dashboard.
Go to helpers and add a new āRiemann sum integral sensorā. After that, you can add as additional device to the energy dashboard.
Hi Jo,
Iām new to HA, and am probably making a trivial mistake in getting your Remko Heatpump integration working on our WKF100. All sensors report 0 or N/A valuesā¦
Could it be the API or codes have changed? Iām running version 4.27.
I also get āint() canāt convert non-string with explicit baseā errors on the RemkoHeatpump().api_request calls that expect a numeric result:
RequestedWatertankTempSensor,
PowerConsumptionSensor,
CurrentWatertankTempSensor,
CurrentOutsideTemperatureSensor,
CurrentHeatingCircuitTemperatureSensor,
CurrentHeatingWaterTemperatureSensor.
I resolved the error by casting the call to str (ie. str(RemkoHeatpump().api_request(<api code>))
I dont have version 4.27.
Can you confirm you get a response if you go to the address: http://BASE_API_URL/cgi-bin/webapi.cgi (check your ip address).
Sometimes (if ha just start) it does not give any results so this errorās can occur a few times a day in the logs. I think the remko interface is not quick enough.
I did not receive any updates from Jan about this.
The problem we have now is the version I have running in my REMKO unit is older, so it seems there is a newer endpoint I donāt know of. REMKO doesnāt have any test software or demo versions available so I can not troubleshoot on the API connector.
I have asked to update my system to the latest version, but no response jet.
BTW is one thing you can try, but not sure if this is working:
Change the URL from http://BASE_API_URL/cgi-bin/webapi.cgi to http://BASE_API_URL/ucresponse.cgi
If I am changing it to:
http://BASE_API_URL/cgi-bin/ucresponse.cgi I receive a long number:
27DCE533202218C0A8B23D2104001C0027F1FD874D40F69CBA9624BC274C9A2880342878DB3BCB
I modified this URL in the remko.py file. Do I need to trigger the integration to see the sensors?
