power_precision and voltage_precision settings with Nous A1Z are not working

[chris777c]

What happened?

Hello,

I have a plug Nous A1Z with last firmware (version 192), the precision settings seem to be ignored, power and voltage values are always without decimals however energy or current work.

I don't know if it comes from device or z2m and I don't know how to help you for resolved issue ?

What did you expect to happen?

I could like a precision for power and voltage can be set on my device

How to reproduce it (minimal and precise)

Settings :

return : { "child_lock": "UNLOCK", "current": 0.4, "energy": 45.7, "indicator_mode": "off", "linkquality": 123, "power": 90, "power_outage_memory": "restore", "state": "ON", "update": { "installed_version": 192, "latest_version": 192, "state": "idle" }, "voltage": 237 }

[Nitrouze]

I have the exact same problem running a Conbee II adapter. The plug is identified by z2m version 1.32.2 as an TS011F / _TZ3000_2putqrmw model.

[chris777c]

Hello,

A little up

[wherzig]

Same problem here. With Firmware 77 = 1.0.13.

Is there any firmware available to change the precision?

[kladderadeng]

I have the same issue and I updated from 77 to 192 yesterday.

[tlamoureux24]

Exact same issue. Z2M HA Addon 1.34.0-1 A1Z firmware 192

[wherzig]

After reading some forums, I think that the Nouz A1Z does not support better precesion. zigbee2mqtt does just offer to change it but this does not mean that the device support it.

[chris777c]

Thank you for you reply, I close ticket

[prahal]

It seems Nous A1Z supports better precision as in cluster TuyaZBElectricalMeasurement 0x0b4, the rms_current attribute 0x0508 is in milliamps (read via ZHA in Home Assistant). But the ac_current_divisor is 1000 and the ac_current_multiplier is 1 and cannot be changed at least I failed to in ZHA. At least in HomeAssistant I get via ZHA a rms_current of 20mA for a Bluetooth speaker, but with the default _decimals of 1 for electricalMeasurement and with a divisor of 1000 rounding only give an output of "0".

I took a look in z2m zigbee-herdman-converters it seems rmsCurrent is not rounded i z2m https://github.com/Koenkk/zigbee-herdsman-converters/blob/3839ea6df4f0e66d9fc6f01faffd1298d7e508e5/src/converters/fromZigbee.ts#L788. So I don't know why you have the issue in z2m. But you should at least be able to get rmsCurrent 0,02 from what A1Z produces.
