TS0601 TZE204_s139roas battery issue - Avatto.ts

[sch115]

Hi! Trying to find a way how to solve this issue. Sensor battery is not stated, showed as null. After digging deeper and sniffing datapoints through Tuya gateway, I see these: Temperature: 1, Humidity: 2, Battery level: 4, Unit convert: 9, Temp alarm: 14, Humidity alarm: 15 which does not correspond to datapoints in original converter https://github.com/Koenkk/zigbee-herdsman-converters/blob/master/src/devices/avatto.ts
Is there a way how to test it? I am new to converters and haven't found a way to be successful so far./
