Can't get a full DPs from device (ZMAi-90 Energy Meter)

[JayChun]

Hello! Thanks to contribute the component. It is really simple and easy to do local tuya! I tried to set it up yesterday for energy meter, the model name is ZMAi-90 from AliExpress (https://www.aliexpress.com/item/4000353269379.html)

Smart Life App shows 4 kinds of sensor data and on/off switch.

• on/off Switch
• Energy (kWh)
• Current Watt
• Current A
• Volatge

But Local Tuya in HA integration shows only 2 kind of DPs - 1 sensor(kWh) and 1 switch.

Additionally I have tried to do Tuya Convert, but the convert couldn't find the device. (or the device doesn't allow the convert's vtrust-flash AP) (refer to this https://www.creationfactory.co/2019/12/reverse-engineering-zmai-90-din-rail.html?m=1)

Is there any solution for using a full DPs via Local Tuya?

Can you close your tuya app and home assistant and get a full DPS dump using this

Thanks for your response. firstly I shut down HA and mobile phone also power off. And i tried it, but the Test.py also shows just 2 DPs as below.

But a bit strange thing is that I saw another DPs yesterday as below screenshot even the DPs disappeared quickly from HA

I don't know "10", but I know exactly "18", it is "imeilmsi" number which is shown at device Setting in Smart Life app.

Thanks ,I have this Energy Meter too. I only get the Crypto raw data ,localtuya can't convert data "CVsAAAAAAAA=" . It contains voltage/current/power .

I can get dps from app:

"dps" : {

"17" : "AQAAPAMAAQgEAACW", #alarm_set_2

"1" : 0, #total_forward_energy

"16" : true, #switch

"6" : "CVsAAAAAAAA=", # voltage/current/power .

"10" : 0, #fault

"18" : "111111111111" #meter_id

},

{"mode":"ro","code":"total_forward_energy","name":"正向总有功电量","property":{"unit":"kW·h","min":0,"max":99999999,"scale":2,"step":1,"type":"value"},"id":1,"type":"obj","desc":""},{"mode":"ro","code":"phase_a","name":"A相电压，电流及功率","id":6,"type":"raw","desc":""},{"mode":"ro","code":"fault","name":"告警事件","property":{"label":["ov_cr","unbalance_alarm","ov_vol","undervoltage_alarm","miss_phase_alarm","outage_alarm","magnetism_alarm","terminal_alarm","cover_alarm","credit_alarm","battery_alarm","meter_hardware_alarm","no_balance_alarm"],"type":"bitmap","maxlen":13},"id":10,"type":"obj","desc":""},{"mode":"rw","code":"switch","name":"电表拉合闸","property":{"type":"bool"},"id":16,"type":"obj","desc":""},{"mode":"rw","code":"alarm_set_2","name":"告警设置","id":17,"type":"raw","desc":""},{"mode":"ro","code":"meter_id","name":"设备号显示 ","property":{"type":"string","maxlen":255},"id":18,"type":"obj","desc":""}

Maybe it's related to #87

Hi. I also have ZMAI-90. No news about decoding this string? "6" : "CVsAAAAAAAA=", # voltage/current/power .

[JayChun]

@andrkaz I also checked the log, but maybe there is still nothing updated.

I've been digging around trying to find a solution for retrieving the voltage from this device and found this thread. I'm using codetheweb/tuya-cli at the moment to register the device and then using their get operation to pull data from it. I also found kWH in DPs:1, 0 in DPs:10 (might be relay control), true in DPs:16 (might be relay control), and 111111111111 in DPs:18 (imei..)

Anyone have any suggestions how I can get this data out of 6, it just says undefined for me. I'd like to try to decypher it and see if I can find the voltage. CVsAAAAAAAA didn't look very promising, but CKQACA8AANs does

Thanks for any info

Anyone know what encoding is used when putting those 11 digit strings into the json?

No news on a solution to this problem zmai-90 ?

Thanks. Dont understand how use this in Home Assistant

[sanyatuning]

Hi! I've created a PR https://github.com/rospogrigio/localtuya/pull/473 based on https://github.com/codetheweb/tuyapi/discussions/440 This is not a perfect solution, till you can't configure with the UI, but I don't really understand why. Does anyone know why the hack some "dps" not visible in the UI (config flow)?
