Error POWERMAX_DSX on Line 57 - clage_homeserver.py

Description

Hello,
i want to report an issue
using version 0.1.11 clage_homeserver pip module (used by Home Assistant Integration)
Clage DSX-Touch (set to 18KW)

HASS gives error on
File "/usr/local/lib/python3.10/site-packages/clage_homeserver/clage_homeserver.py", line 57, in mapApiStatusResponse
device_power = float(ClageHomeServer.POWERMAX_DSX.get(heater_status_powerMax)) # Geräteleistung in Watt, 140 => 21 kW, siehe Kapitel 4.9 in der API-Dokumentation

I have writed a smal python script to debug the issue
clage.py
from clage_homeserver import ClageHomeServer
clageHomeServer = ClageHomeServer('...','F8F00******','204******')
status = clageHomeServer.requestStatus() # Request the status
print(status)

getting error on clageHomeServer.requestStatus()
device_power = float(ClageHomeServer.POWERMAX_DSX.get(heater_status_powerMax)) # Geräteleistung in Watt, 140 => 21 kW, siehe Kapitel 4.9 in der API-Dokumentation
TypeError: float() argument must be a string or a number, not 'NoneType'
see relevant log output below

to debug this i have added
#57 print(heater_status_powerMax)
this shows: 120.0

thereafter i have added one line after POWERMAX_DSX =
#192:
POWERMAX_DSX = {
120: 18000,

then the issue was solved, and clageHomeServer.requestStatus() gives me the info:
{'homeserver_version': '1.4', 'homeserver_error': 'OK', 'homeserver_time': '2022-12-31 13:42:37', 'homeserver_success': True, 'homeserver_cached': True, 'heater_id': '204900C***', 'heater_busId': 1, 'heater_name': '', 'heater_connected': True, 'heater_signal': -48, 'heater_rssi': -68, 'heater_lqi': 0, 'heater_status_setpoint': 48.0, 'heater_status_tIn': 22.2, 'heater_status_tOut': 27.5, 'heater_status_tP1': 0.0, 'heater_status_tP2': 0.0, 'heater_status_tP3': 0.0, 'heater_status_tP4': 0.0, 'heater_status_flow': 0.0, 'heater_status_flowMax': 'ECO', 'heater_status_valvePos': 75, 'heater_status_valveFlags': 0, 'heater_status_power': 0.0, 'heater_status_powerMax': 120.0, 'heater_status_power100': 0.0, 'heater_status_fillingLeft': 0, 'heater_status_flags': 1, 'heater_status_sysFlags': 8, 'heater_status_error': 'OK'}

and clageHomeServer.requestSetup()

Thanks, I will look into this the next days. Happy New Year.

Hi Peter @flyingdutchmen1 ,

based on you test, it would be like so:

    POWERMAX_DSX = {
        120: 18000,
        140: 18000,
        160: 21000,
        180: 24000,
        200: 27000
    }

I do not understand, why the value 18000 (18 kW) is present two times. It seems to be more logical, to have the value 15000 (15 kW) for the code 120; like so:

    POWERMAX_DSX = {
        120: 15000,
        140: 18000,
        160: 21000,
        180: 24000,
        200: 27000
    }

Which device do you have? Can you please reconfirm, that 120 ist really 18 kW?

[flyingdutchmen1]

Hi ,
below is the information from the device
Clage DSX Touch
Type: 5V-270P-3H
device is set at 18W
see pictures

from the API manual on page 26 they say:
Ermittlung der eingestellten Leistung bei DSX:
18kW: powerMax=(18/27)*180=120
21kW: powerMax=(21/27)*180=140
24kW: powerMax=(24/27)*180=160

[klacol]

Ah, then this should be correct:

    POWERMAX_DSX = {
        120: 18000,
        140: 21000,
        160: 24000,
        180: 27000
    }

Will fix it accordingly.

The fix is now published as clage-homeserver 0.1.12 package.

@flyingdutchmen1 : I have udated the python package to 0.1.12 and accordingly the reference in the manifest of the home assistant component. Please check, if it works for you. Thank you!!

[flyingdutchmen1]

Hi i just see there was an update to 0.1.13

pip3 install clage-homeserver --upgrade

{'homeserver_version': '1.4', 'homeserver_error': 'OK', 'homeserver_time': '2023-01-04 19:13:23', 'homeserver_success': True,

thx, il will test it in HASS later
