Frequently Asked Questions
Which is better overall: Aqara Single Switch Module T1 (With Neutral) or Shelly 2PM Gen4?
The Aqara Single Switch Module T1 (With Neutral) is the better overall value for single-circuit switching, being cheaper while still offering energy monitoring, full safety protection, power-off memory and a Zigbee router. The Shelly 2PM Gen4 wins if you need two channels, shutter automation or a 3-year warranty.
What is the biggest difference between the Aqara Single Switch Module T1 (With Neutral) and the Shelly 2PM Gen4?
Channel count. The Shelly 2PM Gen4 controls two circuits and can drive a roller shutter or blind with its cover mode, while the Aqara is a single-channel switch. Both include energy monitoring and full protection, and both require a neutral wire.
Which relay can automate roller shutters or blinds?
The Shelly 2PM Gen4. Its two channels and interlock/cover mode with obstacle detection are designed to drive a shutter or blind motor from one module. The Aqara Single Switch Module T1 (With Neutral) is single-channel and cannot control a bi-directional motor on its own.
Do both relays measure energy and need a neutral wire?
Yes to both. The Aqara Single Switch Module T1 (With Neutral) and the Shelly 2PM Gen4 both include energy monitoring and both require a neutral wire at the install point, so the decision comes down to channel count, shutter control and price.
Who should buy the Aqara Single Switch Module T1 (With Neutral)?
Buy it if you only need to switch one circuit and want the more affordable metered module with full safety protection, power-off memory and a Zigbee router, within a Zigbee or Aqara ecosystem with HomeKit.
Who should buy the Shelly 2PM Gen4?
Buy the Shelly 2PM Gen4 if you need to control two circuits or automate roller shutters and blinds, want per-channel energy monitoring, a 16A rating, multi-protocol connectivity and a 3-year warranty.
