All things Shelly

[Tinuva]

Okay so I've ordered 2 x 1PMs from Geewiz and 2 Legrand single bell/dimmer switches. Going to use this a trial for the rest of the house.

Why Legrand if I may ask? Is that just a brand you like or what?

I also noticed Veti seems to be everywhere and have all kinds of modular options with bellswitches too. You could for example add up to 3 bell press switches (without a bell icon on them) into a 2x4 or 4 bell press switches into a 4x4 plate etc. At least on veti 1

I like how they look.

I like how they look.

Haha ok fair enough. How do they feel to touch. You know, that's semi important too when using physically.

I don't know yet, going to trial two of them for a bit and see how it all works out.

Let us know how it works out. Both to touch and if the look turns out what you expected.

Just to sense check myself here.

Can I safely use a Reed switch on a Shelly 1 in AC mode?

Because in my mind connecting one end to the Live and the other to the SW means I’m going to send 240V through the Reed switch when it’s closed?

Or do I need to switch to the above and use a DC input?

Reason I ask is that I do not find a single schematic that has the above with AC configuration so I can only assume there is a reason for it.

Not sure if the reed switch can handle the 220v. Maybe it can who knows.

But I would trust the wiring diagrams of the official shelly website @ https://kb.shelly.cloud/knowledge-base/shelly-1

What are you trying to do?
Why not use the GPI0 0 ?

You most definitely should not be sending any real current through a reed switch, AC or DC.

I'm not too familiar with shelly products but regardless the reed switch should not be connected to the in or out but to a sensor input

No no, it’s not going on the Input or Output, the garage door “button” goes there.

It does onto the SW connector but as per picture the other side goes to Live which is what scares.

Exactly as per the picture that’s their official stuff for a garage door…the fact it doesn’t exist for AC input is what gave me pause.

So it’s fine I’ll just need to re-wire it for the DC output from the motor.

They specifically seem to suggest GPIO and other add on pins would get high voltage.

nope use the reed switch at a low voltage to switch a relay ,then whatever else you want to switch,i wouldnt go higher than say 100ma at 12 v .small 12 v relays are around 45 ma

Oh wait there is one easier way.

Get a 240v reed switch

The relay output is already a dry contact by default on the Shelly 1.

So I’m purely concerned about the Live bridge with the SW input.

The more you learn.

Already have the good old fashioned alarm magnet mounted in place just need to wire it so will just switch to DC.

It just always seemed like the source of my problems with the Sonoff SV and with the Shelly supporting AC I used that from day one and never had an issue.

But now the wireless Zigbee sensors are annoying me and apparently not so rain proof so going back to wired.

you get ready made up relay boards for that ,used on intercoms to unlatch a gate lock .you just add the reed and n/o or n/c on relay .reeds cant handle high voltage really well ,the one mentioned may work ,

Yes…the Shelly 1 is the ready made relay board…

It’s been installed and working for a solid year or two now I just want to add a wired sensor now instead of the wireless one I use at the moment.

I’ll just switch to DC.

My shelly em doesn't respond on the shelly app red led is on but don't see it via wifi.any suggestions

 

[Vades]

Any pointers on where to buy either Shelly 1 or Shelly Plus 1 relays?

SA availability seems lacking.

I got my last Shelly 1 and 1PM devices from aliexpress. Takes about 2 months to get here though.

Thanks, I'd prefer to buy locally though, ICASA approved, just in case there is an insurance issue.
