Looking at installing a bunch of zigbee dimmers in a new build. How has your experience been with these? Have you tried any others and can compare link quality etc?
Couldn’t be happier. They work super well with zigbee2mqtt.
Depending on what you are dimming you can tune the ballast to prevent flicker too.

A 100 A CT would be suitable for a typical Australian home with single phase 230 V AC supply.
But you’ll need to check what CTs are compatible and/or how to calibrate.

No I have a Fronius smart meter as part of my solar install which monitors the whole house. I use the Shelly EM to monitor the pool heat pump and the storm water sump pump. The EM comes with a 50Amp Current Transformer (CT). Oz smart things have additional 50A and 120A CTs on their website, here’s the 120A one.

In the middle of a home reno and I’m exploring putting in Zigbee light switches. Does anyone have recommendations or has done this recently? With the plan of integrating into Home Assistant of course.
Yes I have. I went with Clipsal Wiser. Clipsal Wiser in Australia. Can it be integrated into HA? - #17 by tom_l
If you like the DIN rail mounted style, and you think you might want to also monitor a couple of individual circuits, you can also use something like the Shelly Pro 3EM. Note that even though it’s a 3-phase energy meter, you can just treat the 3 readings as separate circuits in HA. I’ve done exactly this, with one clamp measuring the whole house supply, and the other 2 clamps measuring individual circuits. The only downside to this is that the Shelly app adds all 3 readings to give you a “Whole house” reading, but I just ignore that and reference the separate readings in HA.

Does that mean you don’t need a bypass to prevent flickering?
Theoretically yes.
Setting the minimum ballast level just high enough to keep the two wire dimmer operating and selecting the right dimmer type should prevent flicker.
However I don;t think that helps when the light is off. So if your lights draw too little current when off you may also need an external ballast to prevent the lights flickering.
I’m using Clipsal downlights with clipsal dimmers and am still playing with those values on a couple of 4x light circuits.
They don’t “flicker” as such but occasionally my auto-light brightness automation causes a noticeable brief dip in brightness at the lower brightness levels (< 20%). It’s not the auto-brightness value (that is quite smooth) but I’m beginning to suspect the dimmer does not like receiving updates too frequently.

Thanks that all makes sense. There are some good features. I’m really contemplating these or the oz smart zigbee dimmer modules. At 1/3 the price. Did you contemplate any other dimmer modules? What made you go for these in the end?
Yeah I looked at those. I think they might have been out of stock when I was ready to buy.
You are right thanks Dave - I checked and have a 63A main circuit breaker.
I do like the DIN rail mounting actually, and I was surprised that Shelly doesn’t seem to do a single channel 120A DIN mounted EM. I would also prefer a newer generation device than the Shelly EM, which is still Gen 1. I did not realise that the 3-phase meter could just be used for 3 separate circuits, so that looks like the best solution so far - thanks!

My single phase house has a 100A mains fuse.
Suburban Sydney, built 1991.
(I respect your experience @sparkydave, I’m just providing extra data to help people select the right solution for them)
Apparently Shelly are announcing some new products in a live stream tomorrow (March 5, 17:00 CET). I wonder if there will be some updated Pro models.

Good to know, thanks! I’ll be very interested to read about what they announce.
Fair enough. Like I said, “usually”, but given the CT values that can be purchased, either way you would go with a 100A CT.

BTW, I was just poking around my Shelly dashboard, and it looks like they recently added a feature that lets you properly use the Pro 3EM in mono-phase mode. I enabled it for mine, and it now splits the device into 3 separate ones in the dashboard, allowing you to customize the name of each channel, and no longer adding the values together as if they were in a 3-phase system.

hi all - can anyone recommend the latest smart switch dimmer to use with LED downlights? I’m looking at the Lutron Diva Smart Dimmer switches but i dont think they are available in Australia. and they are 110volt i believe
love the look of them and how diff they are to the older models.
Edit. Looks like this could work nicely. Mercator.SSWRM-WIFI_Mercator Ikuu Smart Rotary Dimmer Mechanism Wi-Fi
However I like the candeo ones better only because I can find a YouTube review from the smart home guy and they look amazing.
I wonder if anyone has used the ikuu rotary dimmers here ? I spoke with Ikuu and they confirmed that it dims but there’s no push button on this so you can’t turn the lights on and off seems like Candeo is the way to go
thank you
That is incorrect. These DO have a push button function to turn the device on and off.
It even says so on the product page:
“Includes push button”
I have deployed a few of these through my home.
They are Tuya based Zigbee or WiFi devices and work quite well.
Whirlpool forums have a lot of good information and experience on these.

Home Assistant integration is provided by:
A) a core Tuya Cloud Integration,
B) a local Tuya network integration via HACS:
C) a Zigbee2MQQT integration directly to the device.
