Neo NAS-AB02B0 (alarm/siren) missing power indication

[70MM13]

What happened

While fooling around with my new device I think I found a missing feature.
It appears this device is very similar to the Wifi version
Not only has that page a nice list of the alarm sounds, I also noticed the "power type" status:

• dpId 101 - power type (1 - battery high; 2 - medium; 3 - low; 4 - usb port)

In my debug log I have correct reportings of that id:

Received Zigbee message from 'NEO_siren_alarm', type 'commandSetDataResponse', cluster 'manuSpecificTuya', data '{"data":{"data":[0],"type":"Buffer"},"datatype":4,"dp":101,"fn":0,"status":0,"transid":2}' from endpoint 1 with groupID null
Received Zigbee message from 'NEO_siren_alarm', type 'commandSetDataResponse', cluster 'manuSpecificTuya', data '{"data":{"data":[4],"type":"Buffer"},"datatype":4,"dp":101,"fn":0,"status":0,"transid":2}' from endpoint 1 with groupID null

and can confirm the data:0 is on battery and data:4 is on usb power.

So my request is, can we have a reporting on this?

You can check if it work by replacing https://github.com/Koenkk/zigbee-herdsman-converters/blob/9162491ef881debca91e365cebe2ed61b2f63d61/converters/fromZigbee.js#L1859
with

            case tuya.dataPoints.neoUnknown1: // 0x0465 [4]
                const lookup = {1: 'battery_high', 2: 'battery_medium', 3: 'battery_low', 4: 'usb'}
                return {power_type: lookup[value]};

Thanks, tried it and works almost correct.
4 for usb is ok but in contrary to the given values I get 0 when on battery power. So it's not clear if 1,2,3 are used or maybe not.
I now have
const lookup = {0: 'battery', 1: 'battery_high', 2: 'battery_medium', 3: 'battery_low', 4: 'usb'}
and am looking for a way to simulate low battery or something :)
edit:
Ok I don't have a regulated power supply but came up with the following:
0 with full batteries (6,4V - 2xCR123A)
1 not seen
2 at 5 V
3 at 3.3 V

So I guess the battery range is 0..3 and 4 for usb. Maybe the following is an option?

const lookup = {0: 'battery_full', 1: 'battery_high', 2: 'battery_medium', 3: 'battery_low', 4: 'usb'}

I'm fine with it, does it work correctly? Then I can add it

yes, thank you

Added, also added battery_low true/false.

Changes will be available in the latest dev branch in a few hours (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html)

Nice, thanks a lot
