Askoma Heizstab bricht nach kurzer zeit ab, http/json Einbindung

[tobildm]

Hallo, ich habe mit meinen Heizstab das Problem, dass die Leistung nicht geregelt wird sondern nach kurzer zeit abbricht. Ich habe mal die LOG kopiert, vielleicht sehen die Experten hier gleich das Problem. Der heizstab ist ein Askomat der mit http/json eingebunden ist. (LP-2)

Hier nochmal die .yaml zum Heizstab

• name: Askoheat
  type: custom
  icon: waterheater
  features:

  • integrateddevice
  • heating

  enable:
  source: http
  uri: http://10.0.0.52/getema.json
  method: PUT
  headers:
  - content-type: application/json
  body: '{ "MODBUS_EMA_SET_HEATER_STEP": "{{ if .enable }}1{{ else }}0{{ end }}" }'
  timeout: 10s

  enabled:
  source: http
  uri: http://10.0.0.52/getema.json
  jq: |
  .MODBUS_EMA_SET_HEATER_STEP | tonumber |
  if . == 0 then "false"
  elif . > 0 then "true"
  else "false" end
  scale: 1
  timeout: 10s

  status:
  source: http
  uri: http://10.0.0.52/getema.json
  jq: |
  .MODBUS_EMA_HEATER_LOAD | tonumber |
  if . == 0 then "B"
  elif . > 0 then "C"
  else "F" end
  scale: 1
  timeout: 10s

  maxcurrent:
  source: http
  uri: http://10.0.0.52/getema.json
  method: PUT
  headers:
  - content-type: application/json
  body: '{ "MODBUS_EMA_SET_HEATER_STEP": "{{ (div (mul (.maxcurrent) 230) 750) | max 0 | min 7 }}" }'
  timeout: 10s

Und der Loadpoint 2:

  - title: Heizstab

charger: Askoheat
mode: off
priority: 1 # 0 hat das Auto
enable:
threshold: -200
delay: 3m
disable:
threshold: 200
delay: 3m
meter: Heizstab

Die 60 Sekunden passen dazu:⁹

Note: The connection between ASKOHEAT+ and an external client is considered interrupted after 5000 milliseconds. After an interruption of 60 seconds, registers MODBUS_CMD_SET_HEATER_STEP and MODBUS_CMD_LOAD_SETPOINT_VALUE and MODBUS_CMD_LOAD_FEEDIN_VALUE are deleted for security reasons.

Sieht aus, als bräuchtest du einen Heartbeat auf der Modus Schnittstelle, eventuell reicht aber auch schon ein kürzeres interval. Mit 30 Sekunden kommt jeder charger nur einmal pro Minute dran, mit 15 alle 30 Sekunden.

Habe exakt dasselbe Problem. Es müsste periodisch das "Enabled" Kommando gesendet werden, dann wird der Modus beibehalten. Doch wie konfiguriert man so einen speziellen Heartbeat in evcc? In der Doku habe ich dazu leider (noch) nichts gefunden.

Hallo @tobildm , ich hab das mit ein wenig herumprobieren zum Laufen gebracht - siehe #17988 (comment) .

Vielen Dank! Habe es mal implementiert und werde schauen obs bei mir auch funkt. 👍
