Aqara Smart Wall Switch (With Neutral) - Double vs TP-Link Kasa HS220

Safety protection is the differentiator no other switch in this matchup has: the Aqara Smart Wall Switch (With Neutral) - Double includes overheating and overpower protection that the TP-Link Kasa HS220 lacks entirely, and it also wins on switch count, load capacity, integrations, energy monitoring and power-off memory. With a neutral wire in place, this Aqara switch adds energy monitoring on top of its two independent circuits, and once paired to a Zigbee hub it reaches Apple HomeKit, Alexa, Google Home, Home Assistant and, through the hub, Samsung SmartThings and Matter, more platforms than the TP-Link Kasa HS220 covers on its own. The TP-Link Kasa HS220 still has real appeal: it rates higher with owners, carries a longer warranty, costs less, and needs no separate hub since it joins 2.4 GHz Wi-Fi directly, though it only dims one circuit and offers none of the safety protections or energy monitoring the Aqara includes. Buyers with a neutral wire and a Zigbee hub who want the fullest feature set, including safety protection and energy monitoring, should choose the Aqara Smart Wall Switch (With Neutral) - Double; buyers who want a simple, hub-free dimmer with a longer warranty should stick with the TP-Link Kasa HS220.
