Unlike our under-$15 roundup, this isn't a batch we ordered and sorted through all at once — it's a running list we add to one device at a time, and only after it's been installed and left running for a while. Nothing here is a "looked good in the listing photos" pick.
On pricing: AliExpress prices move fast — by region, by promotion, and by how much stock is left on a given deal. We check the live USD price before publishing, but treat every number below as "as of writing," not a guarantee.
Safety & monitoring
Pairs directly to a Zigbee hub — Home Assistant, SmartThings, or Zigbee 3.0 in general — with no separate app or cloud account to set up. Sensitive enough to trip on an incense-stick test, loud enough to actually hear from another room, and small enough that it doesn't read as "sensor" the way a lot of these do. 4.9 stars across 418 reviews at the time of writing.
Lighting
Big enough to replace a room's main light rather than just accent it, and the white / warm / night-light color-temperature switching (via remote or app) covers "working" and "not waking anyone up" without swapping bulbs. No hub required — it runs off its own remote and app over Wi-Fi. MARPOU's a well-reviewed brand on the platform with a genuinely low return rate, not just a listing that got lucky: 4.6 stars across 611 reviews at the time of writing.
Worth knowing: this price is a limited "SuperDeals" flash promo with very low stock at the time of writing — it's likely to jump back toward the $76.70 list price once that stock sells out, so don't be surprised if the number's different by the time you click through.
This list is short on purpose. If you're setting up buyer protection or want to know what to expect on shipping before ordering anything here, our buying guide and shipping guide cover both. We'll add the next device once it's actually earned a spot.
