Differentiate PTM215Z and PTM215ZE ZGP switches

Hi,

I noticed the EnOcean PTM215ZE module is handled as a PTM215Z (commonly known as “Friends Of Hue” switch), but there are some differences between the two: commandID is not the same for every button event.

I’m trying to make a custom converter and device profile for the PTM215ZE, but since it’s tagged with the model ID “GreenPower_2” (because of the same Device Type: 0x02), I have no way to catch the device.

Here are the differences from the commissioning ZCL data (tested with a deconz adapter, 2 PTM215Z and 1 PTM215ZE):

• frame.Payload.options
  • PTM215Z: 62149
  • PTM215ZE: 62081
• frame.Payload.payloadSize
  • PTM215Z: 46
  • PTM215ZE: 27
• frame.Payload.commandFrame.options
  • PTM215Z: 197
  • PTM215ZE: 129

I think there is something to be done before the onDeviceJoinedGreenPower method of controller.ts create the model ID (GreenPower_${payload.deviceID}), but I don’t know where to start (maybe add some infos to GreenPowerDeviceJoinedPayload in greenPower.ts, then the controller can check those infos and build the model ID accordingly?).

Great, sounds like a much better way to identify those devices. I currently reverted all the green power changes since we don’t want to include them in the 1 September release.

Would be great if you could make the PRs again! (for zigbee-herdsman-converters and zigbee2mqtt.io)

[fredericseiler]

Great, I’ll come back to you with a PR.
