Invalid Response error when sending warm water on or off.

[ggamehdtv]

Hello,

I am having an issue with nefit easy http server. When I try to enable or disable warm water it won't change in the nefit easy app. Instead of changing it gives an error in the console of the raspberry:

Error: INVALID_RESPONSE

Hope someone know a fix to solve this because warm water on using http server is someting i'd like to use.

Which endpoint are you using?

[ggamehdtv]

The bridge endpoint

[robertklep]

What's the full URL that you are trying to retrieve? :)

[ggamehdtv]

Curl -XPOST http://127.0.0.1:3001/bridge/dhwCircuits/dhwA/hotWaterSystem -d ‘{“value”:”on”}’

[robertklep]

When I perform a GET (to retrieve the current value), I get this for my Nefit:

$ curl http://127.0.0.1:3000/bridge/dhwCircuits/dhwA/hotWaterSystem
{
  "id":"/dhwCircuits/dhwA/hotWaterSystem",
  "type":"floatValue",
  "recordable":0,
  "writeable":0,
  "value":1,
  "unitOfMeasure":"",
  "minValue":0,
  "maxValue":4
}

Which suggests that you can't write a new value to it (because writable is 0).

Even if it were writable, it expects a numerical value, so the request would have to be something like this:

curl -XPOST http://127.0.0.1:3001/bridge/dhwCircuits/dhwA/hotWaterSystem -d '{"value":3}'

(I have no idea what those values mean)

EDIT

I just realized that the easy command line tool has an option to switch on/off the hot water supply by writing {"value":"on"} (or off) to these endpoints:

/dhwCircuits/dhwA/dhwOperationClockMode
/dhwCircuits/dhwA/dhwOperationManualMode

Try those.
