Help with the homematic ip ccu3 humidity sensor

Configuration
1

Hello everybody,

I hope you can give me a hand, I have looked everywhere and I can’t find any solution for my problem :frowning:

I have installed the integration for CCU3 (Homematic IP) and almost everything is working fine.
There is just a little detail, I am not able to retrive the humidity from any of my devices
When I look at the atributes of my climate entitity, nothing related with humidity is present.
See below an output of all atributes from one of my climate entities

{
“hvac_modes”: [
“auto”,
“heat”,
“off”
],
“min_temp”: 4.5,
“max_temp”: 30.5,
“target_temp_step”: 0.5,
“preset_modes”: [
“boost”
],
“current_temperature”: 23.2,
“temperature”: 20,
“preset_mode”: “none”,
“id”: “INT0000008”,
“interface”: “groups”,
“battery”: “High”,
“rssi_device”: “”,
“valve”: 4,
“level”: 0,
“mode”: null,
“voltage”: “”,
“friendly_name”: “Bathroom”,
“supported_features”: 17
}

I only have 3x types of devices:

  • Radiator HmIP-eTRV-2
  • Wall Thermostat HMIP-WTH-2 (they include humidity sensors, I can see the current temperature in the physical display)
  • CCU3

In the CCU3 web configurator, I have created groups and linked each radiator to it’s respective wall thermostat

This is what I have added to my configuration.yaml

homematic:
interfaces:
rf:
host: 192.168.1.4
resolvenames: json
username: Admin
password: mypass
groups:
host: 192.168.1.4
port: 9292
resolvenames: json
username: Admin
password: mypass
path: /groups
hosts:
ccu3:
host: 192.168.1.4
port: 2001
username: Admin
password: mypass

Any help is apreciated

You should get extra entities for the humidity. Something like sensor.abcdef_humidity.

Edit: Your configuration also is incorrect for HmIP devices. HmIP is using port 2010. Your rf block will use 2001 currently, which is the default if no port is specified.

I am bumping an older thread; hope that is OK. I got the same problem, I have multiple Homematic IP HmIP-WTH-2 thermostats.

I use @danielperna84 Homematic IP integration to connect to my CCU3.

On CCU3 webui I can see relative humidity reading from the thermostats.

In Homeassistant, the unit was detected and I can control it.

In Device Info I also see the sensor for humidity. However, when clicking it, it tells me “This entity is unavailable.”

Is this a bug? Or a config problem?

What can I do to help diagnose the issue?

Many thanks in advance!

Just activate the entity (under advanced settings).

Anyways - here is a screenshot, which might be helpful for anybody else struggling with this:
