Inovelli Blue Dimmer Review — The Smart Switch That Doesn't Switch
This light switch never actually turns my lights off. The power stays on twenty-four seven — and that's exactly why it's the best switch in my house. It's the Inovelli Blue Series two-in-one dimmer, a sixty-dollar Zigbee switch, and after a year with the first one, I just added a second. Here's why it earns a perfect score.
The Basics
Quick basics first — these are Inovelli's specs for the Blue Series 2-1 (model VZM31-SN). It's a Zigbee 3.0 dimmer that also works as an on/off switch. It's rated for up to three hundred watts of LED, it can work without a neutral wire, it handles three-way setups, and it has a full-color LED bar down the side with over eighty configurable settings — dimming speed, ramp rates, notifications, even energy monitoring. I run mine through Zigbee2MQTT into Home Assistant, which is where it gets fun.
My Setup: Top and Bottom of the Stairs
My setup: one switch at the bottom of the stairs, one at the top, controlling smart bulbs in Smart Bulb Mode. That means the switch never cuts power to the bulbs — the paddle just sends commands. Each switch runs different scenes. At the bottom of the stairs, one tap runs the family room lights, and two taps adds my office. At the top, one tap is the stair light, two taps is the whole family room ceiling — all eleven lights.
The LED Bar Color Code
Yesterday, when the second switch went in, we matched its settings to the first one — seventy-seven settings compared — then built the part I really love: the LED bars tell me what's on before I ever look up. Purple means everything's on. Blue means just the stair light. Green means the family room. And red, dimmed way down, means all off. We tested it every way you can control the lights — the paddle, the app, and voice — and the bars track it correctly every time.
The One Annoyance
The one annoyance, and it's real: the brains live in Home Assistant. When Home Assistant goes down, the fancy scenes go with it. That's the trade you make with this kind of setup — worth knowing before you build your stairs around it.
✅ Pros
- A year in, zero complaints — the first switch has just worked, with nothing worth mentioning in a year of use.
- Smart Bulb Mode done right — the paddle runs scenes instead of cutting power to smart bulbs.
- Multi-tap scene control — one tap the stair light, two taps the whole family room; different scenes on each switch.
- LED bar as a status display — purple, blue, green, and dimmed red tell me what's on at a glance, and it stays accurate whether the lights changed from the paddle, the app, or by voice.
- Runs locally over Zigbee — through Zigbee2MQTT and Home Assistant, no cloud in the loop.
❌ Cons
- Home Assistant is the brains — if Home Assistant goes down, the fancy scenes go with it.
- Needs a Zigbee hub setup — you need Zigbee2MQTT, ZHA, or a similar hub to get the most out of it.
The Verdict. Ten out of ten. Only the second perfect score I've given. A year on the first switch with zero complaints worth mentioning, a second one the moment I had the excuse, and more planned for the rest of the house. The Inovelli Blue is what a smart switch should be.
That's the Inovelli Blue — the switch that doesn't switch, running my whole stairway.
Inovelli Blue Dimmer FAQ
What is Smart Bulb Mode on the Inovelli Blue?
Smart Bulb Mode means the switch never cuts power to your smart bulbs — the paddle just sends commands instead. That keeps bulbs like my Philips Hue downlights powered and reachable at all times, and the switch acts as a scene controller. Mine run in Smart Bulb Mode through Zigbee2MQTT into Home Assistant: at the bottom of the stairs, one tap runs the family room lights and two taps adds my office; at the top, one tap is the stair light and two taps is the whole family room ceiling — all eleven lights.
Does the Inovelli Blue need a hub?
It's a Zigbee 3.0 device, so yes — you need a Zigbee hub setup to get the most out of it. I run mine through Zigbee2MQTT into Home Assistant, which is where the multi-tap scenes and LED color logic live. The multi-way and scene features are where this switch shines, and those run through the hub.
Does the Inovelli Blue need a neutral wire?
No. Per Inovelli's specs, the Blue Series 2-1 can work without a neutral wire, which makes it an option in older boxes. It also handles three-way setups, is rated for up to 300 watts of LED (600 watts incandescent), and has a full-color LED bar with over eighty configurable settings, including energy monitoring.
What happens if Home Assistant goes down?
That's the one real annoyance, and it's worth knowing before you build your stairs around it. In my setup the brains live in Home Assistant — the scenes and the LED color engine are automations there — so when Home Assistant goes down, the fancy scenes go with it. That's the trade you make with this kind of setup.
What do the LED bar colors mean on my Inovelli Blue switches?
I built a four-state color code so the LED bars tell me what's on before I ever look up: purple means everything's on, blue means just the stair light, green means the family room, and red — dimmed way down — means all off. We tested it every way you can control the lights — the paddle, the app, and voice — and the bars track it correctly every time.
Is the Inovelli Blue worth $60?
For me, absolutely — it's only the second perfect score I've given. A year on the first switch with zero complaints worth mentioning, a second one the moment I had the excuse, and more planned for the rest of the house. The Inovelli Blue is what a smart switch should be.
