Sadly it's missing Ikea one. They are cheap and most importantly, use AAA standard batteries instead of the coin cell type.

Ikea selle rechargable ones for really cheap additionally.

Coin cell batteries are the bane of my existence. All the temperature sensor I have are all coin cell's. Every year I have to replace them and throw them out instead of using rechargeable batteries that you can reuse, so annoying.

I never knew Ikea had temperature sensors, might replace my current ones with Ikea even if they don't use Zigbee. AAA batteries are great!

I have them and don't really like them (I assume you mean the Thread ones). Battery life is mediocre, worse than coin cell operated Sonoff Zigbee one I have, accuracy is good, but you can't set update rate or threshold or any generally advanced feature.

Sometimes they either stop updating or drop off the network permanently.

I wouldn't really trust them for anything even remotely important.

Shame since they're pretty cheap, perhaps they'll fix the firmware and then they'll be excellent.

Ikea stopped with the Zigbee sensors I think? It is all Matter now?

    Yep, endless grift with this crap. Bought zigbee gateway? Ooops, out of luck, we are selling only Matter comaptible gadgets now..

      Except that many people already have Matter servers with Thread Border Routers in their household. Apple TV, HomePod, Google TV Streamer 4K, various Google Nest Hubs, recent Amazon Echo. Heck, even recent iPhones have a Thread radio, so that they can talk directly to Thread devices [1].

      I have a lot of qualms with Threads, such as Thread device internet access through TBRs that do not allow you to disable NAT64 (or even worse, getting globally routable IPv6 addresses in Thread 1.4), but complaining that people have to buy another device is not one.

      People are far more likely to have a TBR already than an IKEA Zigbee Hub. And even if they hadn't, they could get any other TBR/Matter Server besides IKEAs. So it's not a great way of selling smart home hubs.

I really don't get this meme. AAA batteries are terrible for most (not all) sensors because it makes the sensors enormous. Like the newer door/window contact sensors. Coin cells aren't expensive, which people often claim. Maybe if you buy them 1 by 1 at the grocery store. If you get the right sensors, battery life can be 2-3 years.

Like, IKEA's Zigbee water leak sensor (BADRING?) with 2 AAAs (1.2V; they don't like 1.5V) has a battery life of 9-12 months. My Aqara water leak sensors (CR2032) have been going strong for at least 3 years. They predate me starting to track it with Battery Notes and that has to be 3 years ago (and yeah I test their functionality every 6 months or so).
