yes, I see the currtemp
is missing from the payload so HA can't render the thermostat component. Check from the console with a show
command to whether you see "Current room temperature: xxx". If not then we know where the problem is.
yeap, exactly. I don't have a good solution proposal. My heating system is external temperature triggered, therefore it doesn't use a room temperature sensor.
My previous setup with the FW200 instead of CW400 published currtemp
, but that was more or less useless since it uses the inbuilt sensor inside the FW200, which is attached to the gas burner. So it's in the heating room, not in a room where there's a realistic and useable temperature. The CW400 deactivates the inbuilt sensor if mounted on the gas burner.
I agree, no easy solution. Here's a few ideas
nested
and build the HA component yourself (for display and adjusting)@joanwa that CW400 has one inbuilt sensor like that Fxyz. But the reason for that decoding-problems is: Junkers/Bosch have used different MessageID's (telegram-types) for that series of moduls. This is true for all of that 'new' EMS2 like modul's like MSx00 and MMx00 and what else. PS: That new modul's can also handle that older MessageID's more or less but are sending messages with new ID's. @proddy For that reason it is required to decode/assign that values dependant on the modul-type (Fxyz or Cxyz). For the value "currtemp" you can find that value (cuurent room-temperature) in the MessageID 677 at byte-position 6/7. Anyway, that CW400 then must be mounted in the room (as I have done) and not in the heater itself. See attached extraction from my documentation:
@norberts1 is that CW400 room temperature sensor only enabled if in the external housing? My CW400, which is mounted onto the boiler doesn't show any room temperature on the CW400 display itself... The FW200 did show the room temperature when mounted onto the boiler. I know this values is useless in this setup, but anyways...
@joanwa I had never mounted a thermostat in my boiler. They where always mounted external. So I can't realy answer your question. I know that there are 3 pins in the boiler, 2 for 2-wire bus and the third for detecting of buildin thermostat. But my CW400 (external mounted, in my livingroom) shows that temperature. You must dig into that 'info'-menu and select that 'heizung' or 'boiler' or what ever is shown in englisch. See attached picture. But anyway, you should find that information in the received telegramm 677_0_0 (01A5) see above.
@norberts1 is you heater set to "Außentemperaturgeführt" or controlled by inner room temperature?
@joanwa this is configureable as many other parts too (see manual). I configured it as: outdoor-controlled with based-fixpoint. But the inner room temperature is still send with that telegram. My configurations see attached picture:
closing this. The problem is in HA that the standard thermostat component doesn't work without having the current temperature.
yeap. will come back to this once I figured out in what makes the room temperature disappear. Apart from my controller sitting on top the heater instead of wall mounted in some room, my setup looks the same, but doesn't show the room temperature.

@norberts1 I just found this:
Der CW400 hat sowohl einen Innen- als auch Außtentemperaturfühler. Wenn er [...] im Gerät eingeclipst ist dann ist der IT-Fühler deaktiviert.
that explains why you see the values and I don't. Unfortunately this also implies that everyone who has the controller boiler-mounted can't use HA autodiscovery in the current form :(
@joanwa so there is still an enhancement to EMS-ESP that if the thermostat is not using current room temperature, then the HA climate component should use the outdoor/outside temperature? As you know right now the climate component is not created but the data is still present in other entitites.

Already wrote in Gitter, just adding as issue here to track. Basically the home assistant autodiscovery features publishes configs into
homeassistant/climate/ems-esp/hc1
homeassistant/sensor/ems-esp/external
and in my setup a state only into
homeassistant/climate/ems-esp/hc1
with climate sample config:
and climate state:
and sensor state:
home assistant logs report the following:

Could not parse temperature from
seems a bit truncated, but even full logs on hass don't show more.The one thing I see here is that climate config
"curr_temp_tpl":"{{value_json.hc1.currtemp}}",
doesn't have an corresponding state to resolve.
