Are Tuya local keys permanent (like a MAC address)? (lemmy.world)

Hi All,

Bargain outlet near me had a bunch of the “monster smart illuminessence” stuff at a price that made me try one.

A few hours later and I have them running properly on LocalTuya. I went and scooped up a bunch more given the success.

My question is: When is the local key issued and when does it change?

I’d like to get them all taken care of and put in the box with key written down so I can delete the official tuya app, and also not have to worry about if Tuya will change it’s dev policy so I can’t get access to the keys anymore.

As a side note, I’ll give Tuya credit, I can easily see where that is a great tool for folks looking to offer smart goods… it’s also exactly why I’ll always be local only.

The main benefit of Matter is that it is split into two layers (Matter and Thread) where as Zigbee is essentially one layer that handles everything. This makes Matter more flexible, since it can work over both Wifi and Thread (and any future protocol at the same layer). At the moment there isn't a huge advantage, but in the future if the standard succeeds, you would hopefully be able to buy most smart devices and use just one protocol (Matter) to control and integrate them.

At the moment, the main advantage I can see is that more wifi smart devices can be locally controlled because they have Matter support (which requires it). Which historically, was limited to HomeKit over WiFi, ESPHome/Tasmota flashed devices, and sometimes through Home Assistant integrations that found a way to locally control devices for a given company.

Because I didn't really explain Thread, I'll just quickly say that it's a protocol much like WiFi and the "closer to the hardware" part of ZigBee. I'd prefer buying Matter over Thread vs Matter over WiFi devices, particularly if you're planning to build out a Thread mesh network (the Matter over wifi devices won't help in that).
