[Feature Request] PoE (Power over Ethernet) variant of the ZiGate-Ethernet hardware? #1

Open Hedda opened 3 years ago

Hedda commented 3 years ago

Please consider making a PoE (Power over Ethernet) version of the ZiGate-Ethernet hardware so it can be powered over Ethernet.

https://en.wikipedia.org/wiki/Power_over_Ethernet

The best would be if could support the IEEE 802.3af standard (alternativly passive 48V PoE) support for single cable deployment.

Reason for wanting PoE support is that it is great when you want to place the gateway in a place where there is no other power.

For ideas, could look at Olimex ESP32-POE-ISO and/or LILYGO TTGO T-Internet-POE which looks to be open source hardware:

As an example of someone implementing Olimex ESP32-POE-ISO for this purpose see Tube's PoE Zigbee Gateway by tube0013

PS: Anther implementations for PoE for a somewhat similar purpose is ZOE2 (Zoe) PoE and Zigbee shield for RPi by Electrolama:

Hi, POE is really good option but for me It have to be an option, I work about this feature and there will be modification on the future version.

Thanks

I agree that it would be best if PoE could be enabled via an optional addon board or via an automatic or manual switch.

I guess that most people will probably want USB-power so that option should always be available unless you would want to make and sell two separate products.

If you look at ZOE and ZOE2 (Zoe 2) PoE and Zigbee shield for RPi by Electrolama they have made it as an addon board

The downside with an addon board is increased complexity and cost for those people who do want to use PoE
