Anyone interested in group buying a couple of shelly IOT relays. They can be used for home assistant / google / IFTT etc.

Shelly 1

The Shelly 1 is currently out of stock.

PS: I'm not making any profit, I want to get some for myself and don't want to pay the high small volume price

I probably saw the same Reddit thread as you did, and I have to agree with many people there that putting these onto my mains voltage circuits without a well known compliance accreditation doesn't appeal.

Their small size certainly appeals though as I don't have a lot of space for this sort of thing in my lockwood walls.

@kiwijunglist I would be a starter. Would be keen on two. Let me know all the details etc.

I am just getting in to this arena as my initial home automation is mainly audio visual at this stage and these could be a great way to add lighting. Been looking/watching the zwave avenue, especially with dimmers, but budget and setup effort a bit daunting at this stage.

Great. I think there might be enough interest for me to go ahead there is someone on discord that said they might be interested in two. I only want one or two for myself, but i would put myself down for three in the hope to offload one or two.

Kiwijunglist - 1 or 2 or 3.
Yoban - 2
tHeRobot - 2?? (I think i spelt his username wrong)

I've been going to the Wellington home automation hackers meet up so i might be able to offload one there.

How it would work.

I would require full payment or 50% deposit prior to making the order

Full payment prior to courier out the item.

I would probably pay a bit extra for faster shipping from Amazon (currently is 6usd standard vs 10usd express i think).

If you live in Wellington could probably drop them off or give you the option to pickup from my home in Kingston or the hospital or the cbd.

I also am interested in a dimmer. Haven't done a lot of research but was thinking maybe zwave dimmer with aotec gen5 usb controller.

I have zigbee already but i think zwave dimmer might be better.

Sorry for the silence - been travelling for work.

Still keen and happy with T&Cs - let me know when ready to place order and PM bank details etc. I am Auckland based. With the USD bouncing around I am guessing sooner rather than later.

I too been looking at the zwave option and the aotec stick gets some good reviews. It also pugs in to Home Assistant nicely. Currently running HA in a container on my NAS via docker as part of my trial.

Hi sorry for the silence.

You are the only definite interest. I need to drum up one or two more people. I think i can find them but work is hectic this week so i haven't been able to work on my sales pitch. I have not forgotten and i am still keen. I have been following the Shelly 2 tasmota github thread and everything looks good. The power monitoring does not work with tasmota yet but i think they will get that going. The power monitor feature is not needed for me.

The mains input is what appeals to me with these, but I would want to see how they work for people with long 3 and 4 way switch wires around the place. A previous attempt with a different switch had it just thinking the switch was on all the time with the capacitance between the switch wires.

If you use a sonoff it can cope with long wires on the gpio switch pins if you add a capacitor and a resister.

This device uses mains voltage on the switching pin so it would not be an issue.

What's the draw card for these over a Sonoff? Just the plug and play side of things? Compared to having to modify a Sonoff to get a bit more out of it?

One person supports this post

Differences are:
A lot smaller (fits better behind switch)
Terminals are better quality
Dual relay
Power monitoring
Mains voltage on switching terminals
api without flashing

Shelly 1 has gpio headers

The fitting behind would depend if you have flushboxes or not, some of the older parts of the house here have tiny ones that cant even fit a 4 way lightswitch in them, others are larger, and some of the new wiring has the open back ones so you could fit anything you like in the wall.

sonoff terminals are complete crap, possibly ok for a single piece of 1mm, no good for 1.5 or 2.5 at all because that is stranded.

Yup.

That's why people are quite keen on the Shelly and it seems fairly popular.
