Crawford garage door trigger with Shelly

Hi! I recently moved to a house and there is a garage with Crawford Ultra S garage door driver. I want to control that device from my Home Assistant. The problem is I’m not really sure how can I trigger the opening and closing of the door.

Here is the picture of the back of the device:

I found a manual which (if I understand it correctly) could let me use the port 7 to trigger the gate to open or close. I can’t find any information on how to connect to it though.

Here is the link to the actual manual

My idea is to use Shelly 1 to trigger the gate to open or close and use door sensor attached to the gate so I know when the gate is in open/close/moving state.

Does anyone of you have experience with this gate and could help me figure this out?

Hi, were you ever able to get this working? I have the same garage door. I would like to make it work with Home Assist.

I think I might have the answer for this.
I’ve got a very similar garage door opener - a Cardo Ultra.
Seems to just be branded differently.

The extra feature mine is using is a manual button switch that is attached to 7.
It is attached using an RJ connector. There’s 4 wires but only two are in use at the switch end. The switch is a spring loaded momentary switch, so it makes sense that only two wires are required. They’re shorted/joined and the motor starts moving. The two wires in use are the red and black (position 2/4).

I was about to install an ESP8266 Relay board running Tasmota when I noticed that the connector is RJ10.
I thought it was RJ11 so was about to utilise an old ADSL router cable.

It definitely is not RJ11 on mine.

I’ve ordered an RJ10 cable and will use that instead. I’ll report back once I have.

On the Tasmota flashed device I have set PulseTime 10 which means the relay will turn on then off after 1 second - effectively mimicking pressing the button for 1 second.

Realised the cable connecting an analogue from handset to the base is RJ10.
Took the cable from an old phone, cut off the end and connected it up like the wall switch.

I can confirm this works. I now have a simple button for the Relay switch in HA to press to open/shut the door.

At the moment there is nothing to say if the door is open or closed. I’ll potentially look at adding some door sensors (likely reed switches connected to the ESP8266)…

Now added a very simply RJ10 splitter which is normally used for adding an extra handset to a phone.

Both my Tasmota relay board and the wall switch are connected again.

Means the options to open the door are
RF remote
Wall switch
Home Assistant

HI - totally newbee here.

So I also have a Crawford Port.
Could you please line up the components you have to make this work :slight_smile:

rj10 splitter
ESP8266 ?

Thanks

RJ10 Splitter
RJ10 cable to plug into splitter at one end and then stripped at the other end to use two of the wires.
ESP8266 (or any other similar device) with a relay - all in one boards are available.
I have used an XY-WF36V board, but this required USB or 12V power. There’s other boards out there that can use mains power.
You could also use a Shelly Plus 1 - this can be mains powered and has a dry contact relay.

Anything with a dry contact relay so you can emulate a button press (eg - turn relay on then off within a second). You could probably do this with an optoisolator of some sort rather than a relay, but the relay works.

Thanks a lot - gonna try :slight_smile: :slight_smile:

I too have the Crawford Ultra S and I already have a push button connected to port 7.

But it would be nice to be able to open/close from Home Assistant so I started to look in to using a Shelly 1.

But is it possible to pull power from the Ultra S using one of the available ports to power the Shelly?

I only have a regular outlet available that the Ultra S is connected to and I don’t want to do a hacky MacGyver solution with the outlet to power the Shelly.

I also have the same one. I connected a esphome based garage door controller to the 2/4 pins on a rj10 cable.

When i oress open garage door in HA i hear click….click from the esphome garqge door controller which must contain some kind of relay. Then i hear click…click from the garage door device itself and sometimes it also lights up the built in lamp.

But garage door itself is not moving.

I estimate the click…click has a delay inbetween of about 0.5 seconds.

Any idea of why it is not working for me?
The 2/4 pins are they correct as they are numbered on the rj10 connector?
