  • CAME ZA3 Electric gate and Shelly Uni

    Mea culpa!

    Please accept my apologies, my mind has been on other things today. Ignore my previous posts.

    I've just watched the video again and your multimeter is on the DC range and not AC - which is why it fluctuates around zero. There's probably a healthy 24V ac as there should be on terminals 10 and 11. Your Shelly Uni has a happy LED light on which suggests that it's getting the power it needs.

    It may appear not to be working because you're switching the wrong channel. Someone here will no doubt correct me, but I seem to recall that the diagram on the documentation has the two outputs shown the wrong way around. Try switching the other channel and see if that operates the gates.

    Good luck!

  • CAME ZA3 Electric gate and Shelly Uni

    OK - misread your post. Sorry. If you aren't getting 24V ac at terminals 10 and 11 then neither Shelly 1 nor Uni 1 will work. It's not an issue with the Shelly side of things. To test this, use a piece of wire to short across pins 2 and 7 to see whether that does anything. I suspect it won't.

    Next, check the voltage across terminals 0 and 24 immediately below the transformer and report back.

    I'm having a problem with the power, pins 10 & 11 do not deliver the required power, it seems to be pulsating!? :(

    NonSequitur please can you share how you connected your Shelly Uni to a CAME gate controller?

    Hi there! Pins 10 and 11 are the correct pins on a CAME ZA3 controller for 24V ac. Test it with a true RMS multimeter if you can get one to check that's what's actually being delivered, although I think it's highly likely to be OK if the gate functions correctly in other respects. Is it possible that the wire on the Shelly 1 isn't making a good contact in the connector block?

    Note that you will also need to have the Shelly Uni set up so that the switch is normally off and only on for 0.5s before it goes back to off. The Came controller expects a short pulse rather than a continuous connection across pins. You can do this with a timer off function on the Shelly itself or in whatever smart hub you're using to control the Uni.

  • When garage door open, light on, garage door closed, light off

    I think there's an easier way. You might be able to use a Shelly Door Window 2 sensor to detect whether the garage door is open or closed. Put the magnet on the moving part and the transceiver on something that is fixed. Or a reed switch detector like this; https://www.amazon.co.uk/Zerodis-Magnet…y/dp/B07D6R86LV connected to the Shelly 1.

    The problem with just trying to sense voltage when the motor operates is that it doesn't tell you whether the garage door is opening or closing.

  • Gate monitor state

    Check to see if your gate controller has a state relay which indicates whether the gate is open or closed. The CAME and FAAC gates I've worked on have. Somfy may not have. The relay may require some programming or changing DIP switches on the circuit board of the gate controller.

    What make and model is the gate controller?

  • Gate monitor state

    A lot depends on your gate controller. What make and model is it? You may be able to achieve everything at 12V or 24V (AC or DC) without a reed switch, depending on the gate. To me, that's preferable to adding reed switches and using 240V AC.

    I normally use a Shelly Uni for this sort of sensing rather than a Shelly 1.

  • Shelly 1 with automatic gate

    I tend to use the Shelly Uni for gate automations and I've done it on CAME, FAAC and Somfy gates but not Ditec yet. CAME gate controllers use 24V AC rather than DC and the Shelly UNI can be powered by 24V AC, which is why I started using the Uni in the first place. Here we have DC though, but the Uni is still useful.

    Looking at the destructions for the Ditec CS12M it seems that on the 8 way connector block, connecting one Shelly Uni switch output between pins 1 and 3 would be used for gate opening and the other switch output across pins 1 and 4 would be for gate closing. That is unless you want to use step-by-step pin 5 where one switch can be used to open-stop-close cycle the gates and the other switch pin 6 for partial opening (pedestrian access).

    Now I want to put the gate closing after 10 min (for example) of open!!! How I can get the real state of gate?

    For gate status, it looks as though pin 8 on the same block, marked 'Automation status lamp' gives ground to pin 1's 24V when the gate is open and open circuit when the gate is closed. It looks as though you would need to use a resistor to detect this as shown in the diagram in the manual. This could be used on one of the switch inputs (with the Shelly in detached mode) to provide a gate open/closed status indication. This is what I normally do. Using Home Assistant I can then trigger alerts when the gate is opened, attaching a snapshot from the CCTV camera that covers the gates and sending it to mobile devices using Pushover.

    Automatic closing after 10 minutes can be done by programming the gate controller directly or by using the Shelly.

    Good luck!
