Cheapest Matter Sensors right now
25 Matter-certified sensors from 14 brands are sold in the US at stores we can read a price from. This page ranks them by the lowest price we can show right now: a store price we checked within the last 48 hours, or an Amazon price Amazon returned within the last 24 hours, always with its time. Each has a CSA certificate for the exact model. 16 use Thread, which needs a Thread border router, and 9 use Wi-Fi, which needs no hub.
We check each store’s own product page about twice a day; the time of our latest check shows here.

How the ranking works
- The ranking is by the lowest price we can show for one new unit. A multi-pack, a used or open-box listing and a store page where you pick the variant are never ranked.
- A store price is read from the store’s own product page for the exact model and variant we link to, in US dollars, about twice a day, and shows for 48 hours after our check. A store that states the item out of stock is skipped.
- An Amazon price comes from Amazon’s product data and shows for 24 hours after retrieval, with its time. An Amazon listing reported unavailable is skipped.
- A sensor with no price we can show right now is listed below the ranking with a link to check its price at the store; it is never ranked on an old price.
- Ties go to the first store row on the product page. We rank prices, not quality: the cheapest is not a recommendation.
Before you buy the cheapest sensor
- Check the model and the pack at the store. A price for a two-pack, an older model or a version made for another country is a different product. Match the model number on the store page with the product page here before you buy.
- Count the hub a Thread device needs. 16 of these 25 use Thread and need a Thread border router; if your home has none, add its price. A Wi-Fi sensor joins your home Wi-Fi instead.
- The checkout price is the one that counts. A store’s price can change between our check and your checkout, and shipping and tax are extra. We show each price with the time of the check.

Questions about cheap Matter sensors
What is the cheapest Matter sensor?
It changes with store prices, so this page does not print a price in its text: it ranks all 25 certified models by the lowest price we can show right now, and the first card is the cheapest at our latest check. Every price carries its check time, and the store’s checkout price is the one that counts.
How are the prices ranked?
The ranking is by the lowest price we can show for one new unit. A multi-pack, a used or open-box listing and a store page where you pick the variant are never ranked. A store price is read from the store’s own product page for the exact model and variant we link to, in US dollars, about twice a day, and shows for 48 hours after our check. A store that states the item out of stock is skipped.
How current are the prices?
We read store pages about twice a day. A store price shows for 48 hours after our check and an Amazon price for 24 hours after Amazon returned it; after that the price leaves the page until a new check confirms it.
Does a cheap Matter sensor need a hub?
It depends on its network. Of these 25, 16 use Thread and need a Thread border router, which Google describes as a special hub that connects Thread devices together, and 9 use Wi-Fi and join your home Wi-Fi instead.
