AVM FRITZ!DECT 301 Thermostate to Alexa and HomeKit

Setup, Configuration and Use Items & Sitemaps

Hello, I had problems with the integration of my AVM FRITZ!DECT 301 thermostats to Alexa and Apple HomeKit. I use openHAB 3.4. First an example of my item definition, made in files:

Number:Temperature          dg_zimmer_1_dect301_messwert_temperatur                     "Aktuelle Messtemperatur [%.1f %unit%]"          <temperature>       (gThermostat_Zimmer_1, gZimmer_1_Temperatur)              ["Measurement", "Temperature"]    {channel="avmfritz:FRITZ_DECT_301:192_168_178_1:avm_fb_thermostat_zimmer_1:temperature", alexa="CurrentTemperature" [scale="Celsius"], homekit="CurrentTemperature"}
Number:Temperature          dg_zimmer_1_dect301_regler_solltemperatur                   "Thermostat-Temperatursollwert [%.1f %unit%]"    <temperature>       (gThermostat_Zimmer_1)                                    ["Setpoint", "Temperature"]       {channel="avmfritz:FRITZ_DECT_301:192_168_178_1:avm_fb_thermostat_zimmer_1:set_temp", alexa="TargetTemperature" [scale="Celsius"], homekit="TargetTemperature"}
Number:Temperature          dg_zimmer_1_dect301_regler_absenktemperatur                 "Thermostat-Absenktemperatur [%.1f %unit%]"      <temperature>       (gThermostat_Zimmer_1)                                    ["Setpoint", "Temperature"]       {channel="avmfritz:FRITZ_DECT_301:192_168_178_1:avm_fb_thermostat_zimmer_1:eco_temp"}

String                      dg_zimmer_1_dect301_regler_modus                            "Thermostat Modus [%s]"                          <heating>           (gThermostat_Zimmer_1)                                    ["Status"]                        {channel="avmfritz:FRITZ_DECT_301:192_168_178_1:avm_fb_thermostat_zimmer_1:radiator_mode", homekit="CurrentHeatingCoolingMode"}
String                      dg_zimmer_1_dect301_status_modus                            "Thermostat Modus [%s]"                          <heating>           (gThermostat_Zimmer_1)                                    ["Status"]                        {channel="avmfritz:FRITZ_DECT_301:192_168_178_1:avm_fb_thermostat_zimmer_1:mode"}

Switch                      dg_zimmer_1_dect301_status_batterie                         "Batterie schwach"                               <lowbattery>        (gBatterie_Thermostat_Zimmer_1)                           ["LowBattery"]                    {channel="avmfritz:FRITZ_DECT_301:192_168_178_1:avm_fb_thermostat_zimmer_1:battery_low"}

Alle channel are working and I get values. The first problem is Alexa. I own also FRITZ!DECT 200 outlet

Switch                      eg_kueche_dect200_schalter_steckdose                        "Steckdose Küche"                                <poweroutlet_eu>    (gSteckdose_Kueche_1)                                     ["Switch", "Voltage"]             {channel="avmfritz:FRITZ_DECT_200:192_168_178_1:avm_fb_dect200_kueche:outlet", alexa="Outlet", homekit="Outlet"}

and this device is found by Alexa and could be switched per voice. But my thermostats are not found. But why? I mean that this worked in the past.

The second problem is Apple HomeKit. Actual I use the thermostats over homebridge but I want to make things easier and give openHAB a second chance for HomeKit. I don’t understand, which item I should give

homekit = "TargetHeatingCoolingMode"

Because this mode is missing, I got only a dummy device. In my understanding, I had only one item for the mode and to give two HomeKit definition in the way

homekit = "CurrentHeatingCoolingMode", homekit = "TargetHeatingCoolingMode"

seems not to work.

At least for Alexa you should create a group for the thermostat and present this together with the individual items to Alexa.

Please have a look into the documentation where also am example thermostat definition is included

Hi Matthias,

first I thought “Oh,have I actually overlooked this?”, but in my groups I have defined for the example thermostat:

Group                       gThermostat_Zimmer_1                      "Thermostat Zimmer 1"                             <radiator>          (gThermostate, gMesswerte_Thermostate, gZimmer_1)         ["RadiatorControl"]    {alexa="Thermostat", homekit="Thermostat"}

As I said, I imagine that it has worked before. In the last few days, I have only completely reset my openHAB (new Installation with Ubuntu Server 22.04 LTS) and also reset the connection to myopenHAB and Alexa. Now the thermostats are no longer found.

4

Worked before?
Also with oh3.4 or with an older version?

5

I had a openHAB installation since version 3 and updated every half year. But I can’t remember when I could stopped.

6

With oh3.4 the handling of %unit% seems to have changed (actually it has not changed but per my understanding of the issue it was a bug before and some things within OH only worked because of the bug and stopped working now)

Please see this issue

Maybe for a test change your item definition

Hi got Alexa working again, not sure how, but now the Thermostat are again found. Stays the HomeKit Problem.

I found something here. So there are

org.openhab.homekit:thermostatCurrentModeHeating=COMFORT
org.openhab.homekit:thermostatCurrentModeCooling=ECO
org.openhab.homekit:thermostatCurrentModeOff=OFF

possible to define as an advanced mode. But this is missing in the documentation to HomeKit. But in the end I run also into the problems which is the correct mode and Heating Mode. Is there anybody, which has an working example of AVM thermostats?

8

I cannot help with homekit but would be interesting to know (also for others) how you fixed your issue?

As I wrote, I am not sure. In the last days, I had to restart the complete OS because of a kernel update. And I removed all HomeKit things from the thermostat channel definition. I only had now the group for each thermostat with

alexa="Thermostat"

assigned and two channels:

...:temperature", alexa="CurrentTemperature"}
...:set_temp", alexa="TargetTemperature"}
