Inovelli Blue Series 2-1 Smart Switch (VZM31-SN)

Compiled by SmartHomeWorkflow Research · Inovelli · Switches & Dimmers · ~$60 (at time of research — never treated as a live price)

Exactly which product this is^[2][7]

Model number: VZM31-SN
Generation: Not established
Region this page covers: Not established
Also sold or listed as: Not established

“Not established” means we have not sourced that detail yet — not that the product has no model number, generation or regional variant. We publish the gap rather than filling it.

Compatibility

Ecosystem	Support	The catch
Amazon Alexa	PartialPartial support — see the catch^[3][8]	Only via Amazon Echo models that contain a built-in Zigbee radio; Inovelli's chart says 'yes, but only certain hubs.' Feature depth on Echo is not documented.
Google Home	Doesn't workVerified: does not work with this ecosystem^[3][8]	Google is listed as not compatible on Inovelli's Hub Platform Compatibility Chart; Google Home hardware has no supported path to this Zigbee switch.
Apple Home	Doesn't workVerified: does not work with this ecosystem^[3][8]	Apple is listed as not compatible on Inovelli's Hub Platform Compatibility Chart; there is no documented Apple Home path, native or bridged.
SmartThings	WorksWorks with this ecosystem^[3][8]	Requires a SmartThings hub with a Zigbee radio ('only certain hubs' per Inovelli's chart); Inovelli publishes official SmartThings setup instructions.
Home Assistant	WorksWorks with this ecosystem^[3][8]	Officially supported via ZHA and Zigbee2MQTT with a Zigbee coordinator; Inovelli's chart notes 'we only support certain installations.'

Protocols: ZIGBEE^[1][5][7]

Needs before it works: A Zigbee hub is mandatory for all smart features; the switch ships with no hub and has no WiFi radio. Officially supported platforms per Inovelli's Hub Platform Compatibility Chart: SmartThings, Hubitat, Home Assistant (ZHA and Zigbee2MQTT), Homey, and Amazon Echo models that include a Zigbee radio. The Philips Hue Bridge is explicitly listed as not compatible.^[8]

What it can do^[13]

You can tell it to

On/off
Brightness

It reports

Button pressed

Whether each platform's automations and routines can use it — not just whether its app shows it.

What it does	Alexa	SmartThings	Home Assistant
On/off	? not stated	✓ routines can use it	✓ routines can use it
Brightness	✓ routines can use it	✓ routines can use it	✓ routines can use it
Button pressed	✓ routines can use it	✓ routines can use it	✓ routines can use it

Platform documentation: Amazon Alexa — automation engine ceiling (eight terms observed; residue inconclusive by refusal) (2026-09-01), Home Assistant — automation engine ceiling (2026-08-29), SmartThings — automation engine ceiling (2026-09-01)

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[7]

✓ Works without a subscription: Yes.

Vendor account required: No — no vendor account is involved.^[7]

No subscription, account or paid tier is stated anywhere in Inovelli's product page or help-center documentation, and the device has no vendor cloud to subscribe to — it is a local Zigbee device. Ongoing cost depends only on the hub platform the owner chooses. Re-verified 2026-08-10.

Maintenance reality^[7]

Works without the internet: Yes — the core function runs on the device or your home network. A vendor cloud may still be involved in remote access.^[14]
Zigbee 3.0, 2.4 GHz, 120 VAC, indoor use. Neutral recommended but not mandatory: a no-neutral install requires a bypass at the fixture, which may also be needed with low-wattage loads if lights flicker or the switch reboots. Loads per product page: 600 W incandescent, 300 W LED, 150 W CFL. Works as a dimmer or on/off switch (2-in-1). Multi-way with a dumb toggle, an Inovelli Aux switch (AUX01), or another smart switch via Zigbee bindings. Local Zigbee control; cloud dependence is inherited from the hub platform, not the device.
Security updates: No security-update support date is on record for this model yet. We haven't yet checked whether Inovelli publishes one, so this is a gap in our research — not a statement about the manufacturer.

The catch

Nothing works until it joins a Zigbee hub, and the officially supported list is narrow: SmartThings, Hubitat, Home Assistant, Homey, and Zigbee-radio Echo models. Apple Home, Google Home, and the Hue Bridge are explicitly listed as not compatible, and there is no shipped Matter support.

Who it's for

Hub-based smart home users, especially Home Assistant, Hubitat, and SmartThings households, who want one switch configurable as either a dimmer or an on/off switch, including no-neutral installs with a bypass. Not a fit for hubless setups or Apple Home and Google Home-centric homes.

Sources & method

Numbered sources below back the facts marked with the matching number above. This is a research profile: compiled from manufacturer documentation, certification registries, and published testing — we state facts, not verdicts, and we have not physically tested this unit. How we work →

Where these facts come from

No mark: Everything on this page without a mark comes from the people answerable for it: the manufacturer, the platform's own documentation, or a certification register. That is the standard we hold ourselves to.
Seller's spec sheet: This fact comes from a retailer's or a reviewer's specification listing instead of from the manufacturer. A few compatibility answers still rest on one, and we are replacing those with the maker's own word as we find it. The date is when we last checked, because these listings change without notice.
Someone's observation: This fact comes from an owner, a forum, or a community project — someone with the product in front of them rather than the company that makes it. Worth knowing, and not the same as the maker saying so.

Below is every source behind the facts on this page, numbered so you can trace any one of them. Each is quoted in the source's own words, with the date we last read it — we keep the wording exact rather than tidying it, so you can check what was actually said.

[13] Inovelli's own product page and manual, both read 2026-08-20. The load control: "Leading & Trailing Edge Dimming" with "Adjustable Dimming Speed" and "Adjustable Ramp Rate". The manual states the multi-tap behaviour and, crucially, what it drives: "Scene control allows you to multi-tap your switch to activate certain scenes. Some common examples are: Double-Tap up to activate a movie scene where multiple smart lights turn on to a certain dim level and color; Double-Tap down to activate a bedtime scene where all your lights turn off, doors lock, and temperature gets set to 68; Triple-Tap the configuration/favorites button to lock all your doors and shut the garage door." Inovelli's hub-compatibility chart answers per platform: Hubitat "Yes, all hubs are compatible"; Amazon, Home Assistant, Homey and SmartThings "Yes, but only certain hubs"; HomeSeer "Yes, but requires a plug-in and separate hardware"; and Apple, Google and Philips Hue listed as not supporting the Blue Series. Feature caveat: "Please note that asterisked features are built into the firmware and will only be accessible if your hub supports it." — Read on the maker's own site, verified 2026-08-20

This is a Zigbee/Matter device driven by whichever hub adopts it. No companion app is recorded, and the reason is that Inovelli publishes none — not that nobody looked. ⊕ Worth naming: leaving that answer empty means 'no first-party companion app', which is a different statement from 'nobody looked', and this catalogue's record format cannot yet tell the two apart. — Read on the maker's own site, verified 2026-09-09
