I have recently upgraded to downlights that are dimmable (not smart) and want to install a smart dimmer and switch for 2 sets of lights in one switch plate. I found this on an Australian website https://www.ozsmartthings.com.au/products/shelly-plus-2pm-double-gang-bundle

I understand that the dimming will work via the app or the momentary push-button switch, but I'm not sure if the same switch will also work for on/off.

Do I need another smart switch for on/off? Or is there another smart switch that can do both (on/off and dimming) available and certified for NZ.

Any help/recommendation would be great, I don't want to spend money on very expensive switches.

Thanks

brilliant smart do ones that will dim and use the tuya app platform for quite reasonable prices and will fit into most normal wall plates.

Thanks for the reply, will I need 2 of these?

(In the same plate, I need one switch/dimmer for a group of 4 lights + another switch/dimmer for a group of 2 lights)

If you want them to be controlled separately, then yeah.

Pdl iconic supports Bluetooth or zigbee

I use the zigbee for control.

The Shelly 2pm is not what you want if your after dimming. The Shelly 2pm will only handle turning 2 different circuits on and off as well as monitoring the amount of power each draws.

What you would need would be two Shelly Dimmer2's which depending on space in your wall can be tricky to fit especially if there's insulation in there. The Shelly Dimmer2's handle the On/off and dimming in the one unit but only for the one circuit.

You can also get them from Smartlife here: https://www.sln.nz/shop/shdimm2-shelly-dimmer-2-wifi-smart-switch-175

Is anyone using those?
Do you need one behind each wall switch?

Do you use it with Home Assistant? If so, has it been reliable? Does it function as a router or an endpoint?

Yes, I use it with home assistant, used reliably with both ZHA & zigbee2mqtt, now using the latter. They act as a router, I use a SMLIGHT SLZB-06 as a coordinator.

That's excellent news, thank you. If you were to buy the coordinator today, would you go with the SLZB-06, or the newer SLZB-06M? It appears the newer model is not currently officially supported by Zigbee2MQTT. Perhaps that fact answers the question already.

In case anyone reading this is curious about the array of SMLIGHT SLZB-06 models, and why one is a better choice, I found this video to be helpful:

I love shelly dimmers. I have heaps with iconic momentary switches. Single click turns on and off, holding them down dims or brightens. That is native without doing anything apart from hooking them up.

I'm using then natively with home assistant. As soon as you connect to them to the network HA picks them up and adds them. You can dim in HA easily.

You don't even need the shelly app as you can connect directly to the shelly wifi and then add your home Wifi network to the shelly. No zigbee required.

My views (except when I am looking out their windows) are not those of my employer.

I've been running the SLZB-06M for months now with Z2M and HA, and it has been rock solid. There were some initial reports of instability when the ember devices were first introduced but radio firmware and z2m support has matured. Both devices are on Z2Ms recommended adapter list, so you probably won't go wrong with either.

One aspect I find challenging about all of this is that my knowledge of electrical equipment is extremely minimal. I don't know what a relay is, for example. I also don't know how dimmers work when there are two different switches controlling one set of lights. Moreover, I don't know how dimmers and smart switches work together, e.g. does a dimmer also act as a switch? Can the heated towel rail that is currently wired directly into the wall be connected to Home Assistant? So many questions.

I can always watch YouTube videos and learn about this stuff, but I will always have the feeling that because I don't know what I don't know, the possibility of making an expensive mistake is all too real.

I have spoken with the electrician that wired our house (a new semi-detached townhouse). Our existing switches are all PDL. He knows all about the PDL smart system, and in fact uses their Wiser system in his own home. He knows nothing about Home Assistant — he uses only PDL tech to run his own smart home.

I'm sure it will work out with him if I say, "this is what I want to do with our lights, using the zigbee models that I will control — what do I need?"

I don't how logical it is to ask him "can you do the job using Shelly tech to save some of the hardware cost?". He might he willing to do that, but I suppose if I were him, the extra cost of going out of my way to procure the Shelly stuff would be something I would pass on to the customer.

Another alternative of course would be a different electrician in the Wellington region who is already familiar with the Shelly tech. Does anyone know of one?

Is there there another alternative? Is it realistic to educate oneself about all of this electrical tech, draw up a plan, confirm it will work with an electrician, order it oneself, and have the electrician install it?
