Shelly 1 interference with garage door remote

feiticeir0
feiticeir0 over 2 years ago

Hi all.

I'm having a problem with a shelly 1 and my garage door remote.

Recently I've connected my two garage door motors with shellys 1 .

One of them is working perfectly fine with the shelly safe inside the motor housing.

The other one, before the shelly, I was able to open the door with the remote from 10m-15m away (32 ft to 49 ft more or less). With the shelly connected, I'm only able to open the door with the remote, just from 5m (16ft) away.

The motor board is not the same - one is TE120 (working fine) and the other one is ATH10 (the situation described above).

One thing I did noticed was (the one where the distance was reduced), when I was testing, I had the shelly on a 10m (32ft) wire, rolled around an aluminum ladder on the wall and it was working fine. When I reduced the wire (to leave everything nice and tidy on the wall), this started to happen.

I use the same remote for both (different buttons) . I've switched the shellys - could it be a faulty one - but the problem remained.

Could a ferrite filter solve the problem ? Or at least attenuate some interference ?

Thank you

    UPDATE: I new that shelly could be powered by 24v DC, so I've procured a 24v output - the green PINS bottom left of the pictures - and after searching why I wasn't able to power the shelly with 24v (it…

    glad that it's OK now. When I had little children, the family on the other side of the street could not open their garage door when we had the baby-phone on. It took a while to make that connection…

    they were remote controlled before and shelly reduced remote's range in one case? do you know where is receiver antenna installed? maybe module installation is obstructing the antenna, thus reducing range? what frequency is this remote?

    the antenna is on the front. the shelly is on the back of the casing.  I don't know the frequencies.. It's very hard to find any informartion on the board. I can only find instructions on how to program it - no schematics or specifications...

    I'm not sure about the frequency. There's not much documentation that I could find - I'm guessing 868MHz

    I don't know where to find that. It's not on the PCB...

    or maybe frequency printed on oscillator in receiver and/or remote (if it is not multiplied in the chipset)
