Received some new devices from my friends at icasa.

The ICZB-IW21D looks like your regular Sunricher-OEM in-wall dimmer , with light blue housing. I'm told it's the successor of the ICZB-IW11D, now with power and consumption measurement.

Also received a Zigbee On/Off Switch Pro, ICZB-IW21SW. You guessed it: the successor of the ICZB-IW11SW, again with consumption and power measurement. Note to self: still need to add the DDF for that old switch as well.

Hi @ebaauw, might this just be the same device as #7190 from Robbshop (rebranded Sunricher)? These also have consumption and power measurement.

I couldn't get a DDF to work myself, without lights flickering or other weirdness :smile:. Screenshots are in the mentioned issue and look almost the same to me. I have a few different SW Build's installed of the mentioned device.

If its the same device, can you make it compatible so I can use your freshly generated DDF as well?

[ebaauw]

Could very well be. Note however the differenced in firmware version (r54 vs r58), so there might be subtle changes between the various OEM clones.

You can always copy the DDF, change the manufacturer and model, and try it on the Robbshop dimmer.

Just like the ICZB-IW11D, the device supports commands Trigger Effect, Off with Effect, Move to Level (with On/Off) and attributes Execute If Off, On/Off Transition Time, On Level, and PowerOn OnOff as well as .PowerOn Level_. OnOff and Current Level are reportable.

The consumption multiplier/divisor values are reported correctly:

• Current Summation Delivered is in Ws (1/3600000 kWh), so needs to de divided by 3600 for state/consumption in Wh;
• RMS Voltage is in 0.1 V, so needs to be divided by 10 for state/voltage in V;
• RMS Current is in mA (0.001 A), so can be used directly for state/current in mA;
• Active Power is in 0.1 W, so needs to be divided by 10 for state/power in W. All these attributes are reportable.

Oddly, when the device is off, it reports 1.3V and 17mA. For now, I'll be passing those values to the API, but I'm not sure if that's the best choice.

This should lead to the following resources:
