ZMAI-90 returns DPs without useful info

[Heler]

Hello! I bought ZMAI-90 WiFi Smart Meter. When I try to receive DPs from the device by using code of tuyapi's ReadMe - I get it:

Connected to device! DATA from device: { dps: { '1': 20, '10': 0, '12': false, '13': 0, '16': true } } Disconnected from device.

DP 1 - it is energy consumption DP16 - it is a state of relay

The values of other DPs are static. How can I receive other info? (Current Watt, Current A, Volatge)

P.S. "tuyadebug" shows the same result.

Sometimes there's data shown in the app that's unavailable over the local protocol. There's also "hidden" DPS keys that only report state if you specifically ask for them (not a good way to find these except through fuzzing).

How can I request a specific DP? I will try to get data through fuzzing.

Something like .get({dps: 2}).

    device.get({dps: 1})
    device.get({dps: 2})
    device.get({dps: 3})
    device.get({dps: 4})
    device.get({dps: 5})
    device.get({dps: 6})
    device.get({dps: 7})
    device.get({dps: 8})
    device.get({dps: 9})
    device.get({dps: 10})
    device.get({dps: 11})
    device.get({dps: 12})
    device.get({dps: 13})
    device.get({dps: 14})
    device.get({dps: 15})
    device.get({dps: 16})
    device.get({dps: 17})
    device.get({dps: 18})
    device.get({dps: 19})
    device.get({dps: 20})
    device.get({dps: 21})
    device.get({dps: 22})
    device.get({dps: 23})
    device.get({dps: 24})

The result:

Connected to device!
DATA from device:  { dps: { '1': 20, '10': 0, '12': false, '13': 0, '16': true } }

Disconnected from device.

My bad, try .refresh({requestedDPS: [...list of IDs]}) instead. (See the docs for more details.)

[Heler]

device.refresh(requestedDPS=[20,21]);

The result:

Connected to device!
DP_REFRESH data from device:  { dps: { '6': 'COIAAAAAAAA=' }, t: 1644179276 }
DP_REFRESH data from device:  { dps: { '17': 'AQAAPAMAAPUEAAC0CAAAHg==' }, t: 1644179277 }
Disconnected from device.

Thank you! ;-)

Glad it worked!
