Basic Tuya Siren USB Powered - will this act as a repeater?

I've got the following:

I can power it via USB cable or via Batteries

Isn't the golden rule - if the device is powered from the wall it will work as a mesh repeater? and if it's battery powered it wont work as a repeater?

Well this device can be both wall powered and battery powered. Does that mean this can work as repeater in eitherway? Can this act like a battery powered repeater? lol

and more importantly, HOW DOES ONE TELL if a device is a mesh repeater besides just assuming it is when it's wall powered? Is there a way to test it w/o having to do an actual range testing (trial and error) ?

There are devices that are supposed to run on main's power, but have a battery backup. In that case, the battery will be rechargeable, not replaceable. Which type of battery does the siren have? If it is rechargeable, it may function as a repeater. I have a couple of Z-wave Chimes that function as repeaters, but they plug into the wall.

You can check which Zigbee devices are acting as repeaters by accessing the Zigbee Route Table. You access it using by entering the following URL into your web browser:

http://your.Hubitat.hub.ipaddress/hub/zigbee/getChildAndRouteInfo

In the URL, substitute the specific IP address for your Hubitat hub. For example, mine is 192.168.1.44.

In the resulting table, all of the sensor devices that are Ember Sleep End Devices are listed in the "Child Data" section. All of your repeaters will be listed in the section "Neighbor Entry Table". The section Route Table Entry shows routine paths for any routes that going through repeaters.

The batteries in this siren are standard CR123s and are meant for backup power only.

There are lots of exceptions to this "rule".

wow thank you very much for that walkthru, i found it

I see my Tuya Siren in the Neighbor Entry Table, which is good to know it's acting in repeater mode!

BUT strange that i also found a few sensors in this table as well, such as contact sensor and buttons - these devices can't be repeaters i dont think!

The devices you highlighted show an outCost:0 which means they are not functioning as repeaters. At least, I think that is the meaning.

I wish we can get a confirmation on this hmm

I answered your other Tuya siren question on the other thread. I have the same colored zigbee siren, now assuming it's the same firmware(Tuya constantly changes firmware and manufacturers), mine was acting as a repeater, before I disconnected it, verified by XBee scans of my network identified it as routing

The Tuya siren is showing up in the list with an inCost: 1 and outCost:2, so I believe it has repeater capability. You have to look at the routine table at the bottom to see if anything is routing through it.

Neighbor Table Entry
............
[Siren Tuya _TZE200_t1blo2bj, EE9E], LQI:255, age:3, inCost:1, outCost:2
.............

Same with my device, although currently there is nothing that uses it as a repeater.

so if outCost: is != 0 then it is a repeater? is that how we can tell?
