Aqara Single Switch Module T1 (With Neutral) Review: A 10 A Zigbee Relay With Energy Monitoring
The Aqara Single Switch Module T1 (With Neutral) is the fuller version of Aqara's in-wall relay: 10 A and 2500 W of resistive load, energy monitoring, the complete set of safety cutoffs, and Zigbee router functionality so it strengthens your mesh instead of just joining it. It installs behind an existing wall switch, keeps manual control working, and supports Google Home, Alexa, Apple HomeKit, Home Assistant and IFTTT, with Matter through an Aqara hub. The one requirement is a neutral wire in the wall box. If you have it, there is little reason to buy the no-neutral variant instead.
- Homes with a neutral wire at the switch
- Apple HomeKit users
- Energy usage tracking
- Extending a Zigbee mesh
Pros
- 10 A and 2500 W resistive rating, double the no-neutral version
- Energy monitoring on the connected circuit
- Overheating, overvoltage, overcurrent and overpower protection
- Acts as a Zigbee router and strengthens the mesh
- Works with Google Home, Alexa, Apple HomeKit, Home Assistant and IFTTT
- Matter available through an Aqara hub
- Keeps the existing switch and plate working
- Power-off memory and a manual on/off button
Cons
- Requires a neutral wire in the wall box
- Requires a Zigbee hub, and Matter needs an Aqara hub
- Resistive loads only: no inductive, capacitive or DC support
- Single channel, so one circuit per module
- No dry contact mode, interlock mode or DIN rail mounting
- No Samsung SmartThings support
- Idle consumption is not documented
Who is the T1 With Neutral for?
It suits anyone making existing lighting smart without changing how the room looks or works. The module fits inside the wall box behind the switch you already have, so the plate stays, the switch still works by hand, and nobody in the house has to learn anything new. Platform coverage is one of the broadest in the category, with Google Home, Alexa, Apple HomeKit, Home Assistant and IFTTT all supported, plus a Matter path through an Aqara hub, so it is a safe choice even if you later change ecosystems.
What it does well
The load rating is the headline: 10 A and up to 2500 W of resistive load across 100-250 V AC, double the no-neutral version and enough for demanding lighting circuits. Energy monitoring reports what the connected circuit actually draws, which turns a light switch into a measurement point and is genuinely useful for tracking consumption room by room. Safety coverage is complete, with overheating, overvoltage, overcurrent and overpower protection all present, each of which cuts power when the relay detects a problem. It also works as a Zigbee router: permanently powered devices like this relay messages for battery sensors, so every module you install makes the mesh more reliable. Power-off memory and a manual on/off button round it out.
What to know before you buy
A neutral wire is required in the wall box, which is exactly what many older properties do not have, so check before ordering (Aqara's no-neutral model exists for that case). A Zigbee hub is required as well, and Matter support depends on an Aqara hub rather than being native. The relay handles resistive loads only: inductive and capacitive loads and DC are unsupported, so motors, transformers and some LED drivers are out of scope. There is a single channel, so one circuit per module, and there is no dry contact mode, no interlock or roller mode and no DIN rail mounting, so this is a back-box device rather than a consumer-unit one. Samsung SmartThings is not supported, and idle consumption is not documented.
Is the T1 With Neutral worth it?
It is inexpensive for a module that adds smart control, energy metering and mesh routing to a circuit you already own, and it does it without a visible change to the room. Compared to replacing switches or fitting smart bulbs everywhere, retrofitting relays is usually the cheaper and tidier route, and the wide platform support means the purchase is not a bet on one ecosystem. The only real decision is the wiring in your wall box.
Frequently asked questions
Does the Aqara T1 With Neutral need a neutral wire?
Yes. That is the difference from the no-neutral version, and it is what allows the higher 10 A rating, energy monitoring and Zigbee routing.
What load can it switch?
Resistive loads up to 2500 W at 10 A per channel, on AC from 100 to 250 V. Inductive, capacitive and DC loads are not supported.
Does it report energy usage?
Yes. Energy monitoring is supported, so you can see what the connected circuit consumes.
Does it work with Apple HomeKit?
Yes, along with Google Home, Alexa, Home Assistant and IFTTT. Matter requires an Aqara hub, and Samsung SmartThings is not supported.
Does it improve my Zigbee network?
Yes. It acts as a Zigbee router, so as a permanently powered device it relays messages for other Zigbee devices and helps stabilise the mesh.
