Hi all,
Few weeks ago I asked about help with getting started on knx and openhab, to take control of the knx apartment for which I dont have any documentation whatsoever.
I love the community and openHAB, it’s been great so far and I’m controlling all the lights in the apartment and reading the temperatures in the rooms. I managed to pinpoint all the lights by monitoring the bus and pressing the buttons.
However, I can’t seem to activate my AC, been trying with different options in the config to no avail.
It is a central district cooling system, so I just need to open valve and fan starts blowing cold air.
I managed to configure temperature control (I can set the temperature) and I can enable AUTO mode, but I cannot start or stop the AC which is the most interesting part
So the behaviour:
When I press AC on button, it sends “26%” to the bus address 1/5/48 and then immediately after there is something like “35%” coming on 1/5/49
If you press it again(more speed to the fan), it sends 53% and reads 70% on the 1/5/49, if you press again (3rd speed to the fan) it send 79% and it reads 100% on the 1/5/49. If you press AC OFF it sends 0% and reads 0% to both addresses.
my knx.things:
Type switch : Dressing “Light” [ ga=“1/5/4+<1/5/5” ]
Type switch : Bedroom “Light” [ ga=“1/5/1+<1/5/3” ]
Type number : ACLiving1 “Humidity” [ ga=“1/5/48+<1/5/49” ]
Type number : ACLiving2 “Temperature” [ ga=“1/5/45+<1/5/53” ]
Type switch : ACLiving3 “Mode” [ ga=“1/5/46+<1/5/47” ]
Type number : LivingTemp “Temperature” [ ga=“9.001:<1/5/44” ]
Type number : KidsTemp “Temperature” [ ga=“9.001:<1/5/53” ]
(ACLiving1 does not work, setting the temperature and auto mode works)
my knx.items:
Switch KidsRoom “KidsRoom [%s]” { channel=“knx:device:bridge:generic:KidsRoom” }
Switch Dressing “Dressing [%s]” { channel=“knx:device:bridge:generic:Dressing” }
Switch Bedroom “Bedroom [%s]” { channel=“knx:device:bridge:generic:Bedroom” }
Number ACLiving1 “ACLiving1 [%d %%]” { channel=“knx:device:bridge:generic:ACLiving1” }
Number ACLiving2 “ACLiving2 [%.1f °C]” { channel=“knx:device:bridge:generic:ACLiving2” }
Switch ACLiving3 “ACLiving3 [%s]” { channel=“knx:device:bridge:generic:ACLiving3” }
Number LivingTemp “LivingRoom [%.1f °C]” { channel=“knx:device:bridge:generic:LivingTemp” }
Number KidsTemp “KidsRoom [%.1f °C]” { channel=“knx:device:bridge:generic:KidsTemp” }
here I played with different options, tried dimmer, etc…tried to read the values with 5.001 DPT but did not succeed.
my sitemap:
Text item=LivingTemp
Slider item=ACLiving1 //mappings=[0=“0%”,26=“26%”,53=“53”,79=“79”]
Setpoint item=ACLiving2
Switch item=ACLiving3
}
Frame label=“Hall” {
Switch item=Entrance
Switch item=Foyer
Switch item=Corridor
Please suggest any steps I might take to investigate it more, how to find which DPT is required, what logs to check, what options to play with in the config…
so I basically need to succeed in send “26%” to 1/5/48 to start the AC, and “0%” to stop it.
thanks in advance!
regards,
Vanja
