Getting Device Status

[CraXgt]

Hi there! I've got an Energy Meter telling the current energy used only in a status-answer. Values are not stored in a datapoint. So what I'm trying to call is "GET /v1.0/iot-03/devices/xxxxId/status". Any chance to do it with these nodes?

cheers

I have a similar problem here

It is certainly possible to receive data from Energy meters devices using node-red and this node. I'm using two Energy meters in a photovoltaic application, but about Energy Meter device I fond very different and strange behavior. I study 3 devices, two DIN rail, and one smart socket: all different. For details of known devices see https://github.com/msillano/tuyaDAEMON/tree/main/devices ( look at BreakerDIN, ACmeter, smart_socket).

Each Tuya device is a separate case (see tuya-devices-capabilities-as-currently-known ) but in general it can be said:

• If the GET(SCHEMA) command is accepted it is a good solution.

• Some devices send the V, I, W values in PUSH (e.g. when change see BreakerDIN) others are mute, requiring a mandatory REFRESH to send the data (see Smart_Socket).

• REFRESH (SCHEMA) can not send any data: in general REFRESH only sends data that have changed. Better to use GET(SCHEMA)

• For many DPs GET doesn't work, try SET (null) (see Smart_Socket)

• Some devices do not send separate DPs, but data are coded in a structure (see phaseA on BreakerDIN)

• Some GETs acts like SCHEMA (i.e. return all or many dataPoints, see ACmeter)

• Some data, available in the user interface in 'smartHome' app, are not sent by the device, but are calculated by Tuya-cloud (e.g. today Ele (kWh) by Smart_Socket).

For me the best way is to "study" the capabilities of a new device, perhaps with the help of tuyaDaemon-toolkit, and once you have identified all the capabilities of the individual dataPoints, try the code with node-red.

Regards, I hope I have provided some help. m.s.
