There are threads discussing Tuya devices elsewhere in the forum and I believe there is a lot of specifics around devices with the EF00 cluster. There is even a specific driver for Tuya/EF00 cluster devices so your siren may be included in that already.
Other than that I’m afraid I have no experience with these devices - a search should expose the threads and driver channel invites though and others may be able to help you with some further pointers.
You device has a EF00 cluster so you should try the Personal Tuya Devices driver. See the attached. The link to the driver is near the bottom of the 1st posting.
These drivers are no longer being developed and there are tutorials to help if you wish to do so yourself… Please see recent posts in this thread - good luck
Got into this thread by searching for info on the Sonoff valves. Did the driver worked in the end for you with all the features?
Mind sharing some screenshots on private message, just out of curiosity? Last year a couple of months before these valves came out I bought some Rachio valves and I have to use their App and managed to get them on Smartthings, through Google Home. Not that useful, thus I still use the Rachio app.
Does anyone know why my yoolax blinds all of a sudden report partially open no matter if they are 100% closed or 100% open? They used to report “open” at 100% and “closed” at 0%. Now no matter what percent they report as “partially open”
