Shelly Plus 1 Doorbell 12 V AC - only "long" press is detected

[jan666]

Hello,

I used a Shelly Plus 1 as Doorbell for a few weeks. My old doorbell uses 12 Volt AC so I have running via 12 V transformer rectifier. The physical switch still as 12 V AC which is connected to SW. This works without problems in the stock shelly firmware. But only without eco mode.

I used it via Home Assistant to get notifications.

Now I noticed it's possible to add my setup to Homekit without the need for home assistant. So I installed the Homekit firmware and set it up. Everything looks great but then I noticed I started missing rings. So I began to test and noticed I have to press the switch longer than with the shelly stock firmware to trigger it. So when you just press it for a very short time it does not work. I just reverted to shelly firmware and the problem is gone.

Is this a bug? I'd prefer to use the homekit firmware but I guess I will miss most rings.

Hi,

maybe can you post some logs?

There is a detection for long and short presses, which might somehow lead to that.

I opened the log and pressed a few times (I think at least 6 times). Only got 3 notifications from homekit:

[markirb]

Your short presses are interpreted as double taps and thus trigger only one ring... ?

[jan666]

I dont really know how to read the logs. But I left it untouched for 30 minutes before, made one ring and it was not recognized. That's why I started investigating. Just from my feeling the switch has to be pressed harder than with stock shelly firmware. But that does not really makes sense I guess

[markirb]

No it does not really make sense. Or maybe only after we look deeper.

There is a detection mechanism for short, long and double press, which is actually not needed for a bell. Maybe this stands in the way.

Can you really isolate the event in time when you test and try to annotate in your log what you really did?

I will try to make some better tests when I find time (might take a while)

[timoschilling]

I can confirm that, I have a similar behavior with an UNI.
