Any plans to support ZGP (Zigbee Green Power) endpoint devices in the ZigBee For Domoticz Plugin?

[Hedda]

Do you have any plans to look into supporting ZGP (Zigbee Green Power) endpoint devices in the ZigBee For Domoticz Plugin via zigpy?

I do not think ZGP endpoint devices are ready for zigpy end-users but checkout this zigpy pull request and development discussion:

• Zigbee Green Power Support zigpy/zigpy#1282

• [REQUEST] ZGP (Zigbee Green Power) specification support zigpy/zigpy#341

Most are batteryless/energy-harvesting push-switch devices using PTM216Z, PTM215ZE and PTM215Z transmitter modules from EnOcean:

• https://www.zigbee2mqtt.io/devices/PTM_215Z.html
• https://www.zigbee2mqtt.io/devices/PTM_216Z.html

Most popular are push-switches in the "Friends of Hue" (FOH) partnership based on EnOcean PTM215ZE/PTM215Z and PTM216Z modules.

One of the other open question is weather or not Zigbee Green Power endpoint devices can normally not be connected directly to the Zigbee Cooridnator NCP application and that they instead need a compatible ZGPP (Zigbee Green Power Proxy) device in range on the network to translate the ZGP messages? At least Zigbee2MQTT notes on EnOcean PTM 215Z, PTM 215ZE, and PTM 216Z devices seem to imply that.

"This is a Zigbee Green Power device which allows it to be very energy efficient. Messages from Green Power devices cannot be "understood" by normal Zigbee devices, therefore they need to be "translated" first. Not all Zigbee devices can do this translation, currently the only devices known to do this are Philips Hue devices. This means that the Green Power device has to be in range of a Philips Hue device in order to use it."

However, Silabs has now released EmberZNet 7.3 which release notes seem to imply that it is the first Silicon Labs Zigbee firmware to be able to support ZGP endpoint on NCP application which suggests that ZGP endpoints without proxies could work with it, or?

• https://www.silabs.com/documents/public/release-notes/emberznet-release-notes-7.3.1.0.pdf

"Green power endpoint support on NCP. This release updates green power cluster and framework components to enable the green power endpoint, cluster configuration and command processing to be added on an NCP application."

Note! Also in Zigbee2MQTT notes; "Green Power devices don't support binding and are not included in network scans" for EnOcean PTM 215Z and PTM 215ZE devices, however for EnOcean PTM 216Z it had this added comment; "Binding may work between this module and the actuator, depending if the actuator supports the Zigbee Green Power standard & if the actuators user interface supports "Finding & binding" or "EZ-mode". For more information, contact the supplier of the actuator".

PS: Phoscon (dresden elektronik) posted step-by-step instructions for paring such Friends of Hue switches with their deCONZ solution:
