1. On the Cbus Keypad to control the Garage door, assign a key to a trigger group.I used Trigger Group 225.
2. Set the Key function to Custom and make it On Key, Retrigger Timer, Retrigger Timer and Idle.
3. Next you need to decide which key should indicate the status of the door. I used a different keypad inside the house so I can see if the door has not closed. If you want to keep the existing key that you programmed then just set the Indicators to Status (Dual).
4. Back to Comfort, in your UCM/Cbus assignment, assign trigger group 225 to Counter 225. This way Comfort can 'action' something later on in this setup.
5. Now you need to create the first of two responses on Comfort. I do this as a Bell Press is not reliable enough in my testing. If you have the Garage Door button wired to a Comfort relay then create a Response like this:
Pulse Output02(2) For 10 ! Pulse Output 2 for 500mS #Call it PulseOut2fr500mS
6. Now, to have Comfort control the Cbus trigger group you need to do something with Counter 225. Create a second Response called 'GarageDoorFromCBus' and add the following:
if Counter Counter225 = 255 then Do PulseOut2fr500m //This is the name from the first response.end if
7. Go to Comfort Counters and select 225 and assign the GarageDoorFromCBus response to it. Every time you press the Cbus key it will update counter 225. If it's the ON state then the response will pule the output relay for 500mS and toggle the garage door controller. Once you release the Cbus button it will fire again but this time the response will not fire, because the Counter 225 value is 0 and the door will stay open ready for the next Cbus keypress.
8. For your indicator on Cbus, set the LED assignment under 'Blocks' of that key to another spare key. With this I mean if key 1 is your toggle and key 2 is spare, assign key 2's LED to key 1 under 'Blocks'. Make sure that key 2's function remains <Unused> Now go to Key 2 and set the group address of that key to the group/counter assignment that shows the status of the magnetic sensor. Select Dual Status to see both On and Off.
If you don't want Comfort to also have control over the door then you could probably make it a bit simpler but I have found my way works great even if the grid fails. My door motor is on battery backup, so is Comfort. I just can't trigger it from the Cbus keypad. Oh, one more hint. My remote control is also wired in parallel to the Comfort Relay so it can also control the door independently.
If you don't have Comfort relays on the outputs then setting Cbus to Toggle on keypress might be the only option but I need to caution you that a too quick press might not trigger the door at all. My controller needs at least 500mS between the On|Off toggle to activate the motor. Typically remote controls have relays that toggle around that time frame and push buttons are real-time so you get a 'feel' for it but Cbus calculates the output time in software and it sometimes makes it too short to trigger - you can experiment.
