My terminology might be off but is it fine to have two different devices connected to a garage door opener relay terminals?

My garage door opener motor is connected to an ArrowHead alarm in order to open/close using their app. There is no ArrowHead interface to HomeAssistant (at least not without changing the firmware on the alarm which I’m hesitant to do).

I’d like to expose the garage opener to HomeKit via HomeAssistant so I can access through CarPlay.

So I am considering getting an HA device which would piggy back the output wires onto the garage door terminals with the alarm wires. Is this going to cause issues with the alarm?

No, shouldn't cause a problem at all. Mine is connected to my AAP alarm, the wall switch and a Shelly1 to automate opening/closing of the door, has been this way for well over a year and had zero issues.

One thing to consider would be a reed switch if you don't already have one, you'll want to be fairly sure of the door position before automating anything.

Has no-one been able to work out how to connect to it via ip? Is Arrowhead rebadged something else?

I did find this: Custom Component: Crow Runner / Arrowhead AAP 8/16 Alarm IP Module - Share your Projects! / Custom Components - Home Assistant Community (home-assistant.io) - was active from 2019 to last month. I do note it talking about updating the firmware though, so it may not just be a drop in replacement.

But if you can get access to/control via home assistant, that's probably the sweet spot. I did it with my paradox alarm a few years ago, and it's been accessible in home assistant, openhab and homekit seemlessly.

The bottom line is that you don't know until you try. Output circuitry can work in different ways. If both outputs are 'open collector' then you'd probably be OK.

You can always add a diode to each output to reduce the chance of them interfering with each other.

Most of the posters in this thread are just like chimpanzees on MDMA, full of feelings of bonhomie, joy, and optimism. Fred99 8/4/21

Yeah I have done some investigation and found that project. There are still a few 'gotchas' with it and we lose access to the AAP Smartphone App by changing the firmware. If they get all the features working then I'd consider it but in the meantime I'm more comfortable adding an additional device to the mix.

Wonder if Konnected is of use to you. They did have a replacement main board. Bit I also thought they had a way of just replacing the ip part..... I see in that thread poeple talking about trying to get serial connectivity as well
