Is it? I thought that ZigBee was royalty free and Zwave was not (even because usually ZigBee products costs less than the Zwave ones); is it the other way around?
I just had a look at some Z-Wave motion detection sensor and I soon remembered why I chose ZigBee some years ago: they’re soooo expensive! ZigBee sensors costs half/a forth of the Z-Wave ones!
Why that? Maybe for the more expensive royalty? More expensive components?
Disclaimer: I am wildly speculating as someone who has been been paying attention to smart home tech for a long time, but only minimally so because every time I checked it seemed too immature/janky/proprietary/etc. to bother dealing with. (It’s only recently, with the advent of stuff like Home Assistant, ESPHome, Tasmota, and hopefully-imminent Matter and Thread, that I’ve started to dip my toes in.)
First of all, I feel like a decade ago Z-Wave used to be the cheaper option. Second, my impression is that Z-wave, as an older standard with questionable compliance/implementation accuracy across vendors, just didn’t work quite as well as Zigbee, which I guess would make it less popular over time and therefore eventually more expensive due to fewer economies of scale.
Why do you feel ZigBee is a mess?
Lack of certification leading to non-standard implementations that don’t work well with other devices and instability, especially Aqara
That’s certainly fair. Some of the implementations are terrible, leading to the necessity of things like https://github.com/doctor64/tuyaZigbee
It’s no wonder that ZigBee evolved into Matter
No idea what you’re talking about: https://software-dl.ti.com/simplelink/esd/simplelink_cc13x2_26x2_sdk/3.30.00.03/exports/docs/zigbee/html/zigbee/product_certification.html
https://zigbeealliance.org/wp-content/uploads/2021/04/07-4842-13-Zigbee-certification-policy.pdf
If you’re complaining that the Zigbee standard is open and anyone can write their own implementation, you might be in the wrong place.
Don’t buy non-certified Zigbee products. Simple as that.
Not the guy your asked, but I’d say everything proprietary is a mess, by definition.
ZigBee is an open standard
No it is not! It’s a standard, but is by no means an “open” one. Use of it requires paying royalties to the Zigbee Alliance.
Is it? I thought that ZigBee was royalty free and Zwave was not (even because usually ZigBee products costs less than the Zwave ones); is it the other way around?
I believe that Z-wave is more open then Zigbee (although it didn’t start out that way, and it’s unclear to me whether it’s completely so now or not).
Thread exists because it’s meant to be the royalty-free replacement for both of them (and the first royalty-free standard since X10).
