So I finally got a sketch that gives me all of the functions that I need for my garage door. The two main things that I needed were a way to toggle the door opener, and a way to display the current state of the door in Domoticz. Getting to the door to toggle open and closed was easy. The hard part was getting Domoticz to display the state of the door. I was told by @AWI that I needed a V_TEXT variable and a S_TEXT sencode:sor type. He mentioned that these were not available in version 1.5, but they could be added manually in your sketch by adding these lines of code to your sketch:
// new V_TEXT variable type (development 20150905) const int V_TEXT = 47 ; // new S_INFO sensor type (development 20150905) const int S_INFO = 36 ;Here is the final working sketch:
/* MyGarageDoor for MySensors Arduino garage door control June 16,2016 This will allow the MySensors gateway to monitor and control your garage door opener. This will monitor the internal upper and lower limit switches of the door opener to determine door position for status as well as have a relay switched output that can control either the momentary contact switch connected to the door opener or wired directly to the switch contacts of a door opener remote to activate the door. This sketch features the following: Allows you to monitor the door position and return it's status based on the following: 1 - When either the upper or lower door limit switches are reached, the door is said to be either fully open or fully closed. When a limit switch is triggered, the lastLimit and currentState variables are set to either OPEN or CLOSED based on the limit switch that was triggered. 2 - If the upper and lower limit inputs both read high, then the door is said to be in motion. The door's direction of motion is determined from the lastLimit variable. If the lastLimit of the door is OPEN, then the currentState variable should be set to CLOSING. If the lastLimit of the door is CLOSED, then the currentState variable should be set to OPENING. Checks for door obstructions and throws an error by checking the currentState and lastLimit variables when the upper limit is reached. If the upper limit is triggered and the currentState is set to CLOSING and the lastLimit is set to OPEN, this should indicate that the door reversed when closing and returned to the fully opened position. The error state should only appear if BOTH the lastLimit and currentState conditions match. If lastLimit is OPEN and the lastState is OPENING, this would indicate that the door was manually reversed. This chech should only be needed when the upper limit is reached. Allows you to toggle the opener to either open or close the door. When the door is toggled, the currentState should be checked and if the state is either OPENING or CLOSING, the currentState should invert telling that the door has changed direction. This is done to prevent an error if the door is reversed manually when closing.

@Dringie The only thing I think that I am going to add for now is to turn this on as a repeater node. I have this wired for power with an old modified wall brick cell phone charger that was 5 volts, so it will be powered all the time. I think it is a good place for a repeater anyway. If you find any problems or can suggest any improvements, I am all ears.

I will also use signing when I get round to building this node.
Waiting for the signing chips from China.
I might add a relay for lights, so the lights come on at night when opened. (Night lua code to be used in domoticz).
Postman feature is something I'm going over in my head. E.g.. When postman delivers a parcel I can remotely open the garage slightly and it close again after 30 secs. Not sure if I want to write code in the node or in Domoticz. I think the node would be more fail proof.

Hormann motor, 3 section up and over door. I have placed position magnet sensors on the door runner.
My door works like yours with obstacles.
I will wire my node straight into the motor.
For the postman feature, I was going to add an extra reed switch on the runner to stop the door at a low hight.
-
I had some problems using magnetic reed switches with my old HA setup. My main problem was that when the door would open, it would not always stop in the same spot. It was close to that spot, but enough off where the magnet wouldn't register. That was why I dug into the opener to find the limit switches. Going that route has been a ton more reliable since I am getting the state right from where the door opener tells the door to stop.See my very first pic in this post.
-
The idea of using relay is good as relay control one electrical circuit by opening and closing contacts in another circuit. In the programing model try to give a trigger input. This would work.

thanks

Some faults? Ah well then, that's easy to fix!

All the psychic team are on holiday, so you will have to help those who might be willing to help you. So.....
- Post the code (in full) that you have problems with (use code tags </>).
- Post the detailed messages for the errors you enounter.
- Tell us exactly what is wrong and/or why you think it is wrong and what you are expecting.
