Amazon Echo Dot (5th Gen) Smart Speaker with Alexa (B09B8V1LZ3)
₹4,490
A capable Alexa endpoint with one specification people assume and do not get: it is a Matter controller but not a Thread border router, so Matter-over-Thread sensors still need one elsewhere in the house.
Full details →Who the Aqara Presence Sensor FP2 mmWave Multi-Zone Occupancy Sensor is for
Buy it if: Anyone whose lights keep switching off on a person sitting still, and anyone wanting room-level presence rather than motion.
Avoid it if: Anyone wanting a battery sensor -- this needs permanent USB power -- and anyone on a tight budget, where a PIR does most of the job.
Who the Amazon Echo Dot is for
Buy it if: Anyone adding Alexa voice control to a second room, or wanting temperature-triggered routines.
Avoid it if: Anyone who needs a Thread border router, or wants music quality from a single small driver.
