Virtual RMU not passing temperature to Nibe F1145 heat pump #78

Closed accomco closed 1 week ago

accomco commented 1 week ago

Most importantly @elupus, enormous thanks for both this component and your Nibe Uplink integration. The latter provided us with years of sterling service and we really appreciate your time and dedication.

So like others, having been obliged to transfer to MyUplink, we decided to implement a local solution using esphome-nibe.

The transfer has been seamless, but the one feature we’d really like to get back is the ability to pass back a temperature reading to the heat pump (which we did before using the smart thermostats feature). The virtual RMU was just what we wanted.

Unfortunately, we cannot get the heat pump to recognise the virtual RMU temperature we're trying to pass to it.

Below is our configuration, which builds fine (‘system: 3’ in place of ‘address: RMU40_S3’ per your convo with @svollebregt).

The ‘passback’ temperature (from HA) appears correctly in a climate entity within the esphome integration, but I cannot get this to reflect in the heat pump. On the F1145, S3 and RMU for S3 has been enabled within service menu 5.2.

I’ve also tried this adapting the code, enabling RMU for S1. In this case, the passback temperature in the esphome integration becomes the BT50 room sensor temperature.

I have also tried enabling and disabling the menu 1.9.4 ‘Control Room sensor syst 1’ option.

I've a suspicion that one of the elements in the config might be conflicting. Apologies if I’m making an obvious mistake, but any advice on getting this to work - as @OnlyRobin has managed - would be really welcome!

elupus commented 1 week ago

Did you switch the mode of the cimate entity in home assistant from auto to heat cool?

accomco commented 1 week ago

Yes, I switched the climate entity which appears in esphome to Heat/Cool (without which it does not display a current_temperature attribute). The S1 climate entity created by esphome-nibe is on 'heat' - the pump rejects it being set to heat/cool. Any ideas?

elupus commented 1 week ago

Do you have 3 climate systems? To control any real temperature it need to be linked to an actual climate system on your pump.

A standard pump only has system 1. For extra climate systems you need stuff like ECS addon which has separate circulation pump.

So set it to run on system 1.

Hi @accomco

I have it like this,

# Accessory version response

  data: [
        0xEE, # RMU ?
        0x03, # RMU version low

  ]

# Unknown response that nibepi uses

Add a virtual RMU on S1, if you have a real one choose system 2/3/4

climate:

Add a temperature sensor taken from home assistant to use for virtual RMU

svollebregt commented 1 week ago

For me it works, but I have set all instances for the RMU to S1 (response, sensor and acknowledge) and enabled RMU1 in my F1255.

accomco commented 1 week ago

Hi all, thanks very much for suggestions.

We only operate System 1, and I have previously tried the following config with the RMU enabled for S1 (other settings per previous post):


# Add a virtual RMU on S1
climate:
  - platform: nibegw
    name: s1
    system: 1
    sensor: current_temperature_s1

# Add a temperature sensor taken from home assistant to use for virtual RMU
sensor:
  - platform: homeassistant
    id: current_temperature_s1
    entity_id: sensor.nibe_passback_thermostat

With the above config, the pass back temperature is ignored, the pump uses the BT50 temperature, and the additional climate entity (Nibe_GW s1) shows the BT10 temperature.

I shall try @svollebregt suggestion (setting ‘response’ and ‘acknowledge’ to RMU40_S1) with the above config.

elupus commented 1 week ago

Dont add S1 system responses manually if you run a virtual rmu. They will interfere

accomco commented 1 week ago

Thanks @elupus. Can you help me out with what you mean by 'S1 system responses' please? Which of the elements in the 'Complete config' I should not include if I wish to use a virtual RMU?

elupus commented 1 week ago

You dont need any of the RMU40_XX constants.

accomco commented 1 week ago

Thanks again @elupus. Unfortunately still no joy! The RMU climate entity created by esphome is still showing the BT50 temperature reading, not the one I am passing to it. I have:

  1. Removed all RMU_40_XX constants from the config
  2. Enabled RMU on S1
  3. Turned off the 'control room sensor syst 1' in menu 1.9.4
  4. Verified that the pump is not alarming

System runs - seems to accept the virtual RMU exists - but does not accept the temperature reading from it.

Config is now:

F1145 running the latest Nibe firmware (9699R7). Might you have any ideas?

elupus commented 1 week ago

Have you turned on the flag to use room temperature to control the climate system in the pump?

accomco commented 1 week ago

Yes, I have tried with this flag (in menu 1.9.4) set to on, and also to off.

svollebregt commented 1 week ago

If you have both a BT50 and RMU40 it will by default use the BT50. I disconnected mine.

accomco commented 1 week ago

Great minds. I have just returned from doing just that, after which all works as it should. Thanks to all.
