Multiple Shelly 1 in close proximity

    Hello,

    I have an application where I need to implement 8 zero volt contacts, to automate 4 separate garage doors, each needing one contact for open, and one for close. I would prefer to use 2 x Shelly Pro 4PM, but unfortunately they don't have zero volt contacts (which is super annoying - Allterco, are you listening?!)

    So, to achieve this, I need eight Shelly 1 units (unless someone has a better idea). Is it ok to have them all in very close proximity (as in, all on the same DIN rail, in DIN rail clips). Is this likely to cause me a problem, either with WiFi, or heat?

    I know I could use the Pro 4PM with separate relays, but that's getting silly - two Pro 4PM units, and eight relays!

    Shelly pro 2 has TWO „dry“ (zero volt) contacts and is build to mount on a DIN rail.

    Thank you so much. I didn't know the Pro 2 was released!

    You are an absolute star!

    Edit - It seems that in the UK we are not so lucky (Brexit has already shown that :rolleyes: )

    The Pro 4PM is the only Pro model available here.

    Such a shame. Thank you for the advice, though. I will keep an eye out. Unfortunately I'm installing within the next seven days, so it's looking like I'm back to Shelly 1 units. Or lots of relays.
