TP-LINK PoE Splitter + Cisco 3750 + SNMP + Home Assistant

Using the Home Assistant SNMP Switch component, it's easy to enable or disable PoE on a port of my Cisco 3750 switch.

The PoE device can be any PoE device, most like an IP camera. I used a Raspberry Pi with TP-Link PoE splitter for ease of demonstration.

This example uses port 41

switch:
- platform: snmp
name: SNMP_switch_41
community: community_name
baseoid: 1.3.6.1.2.1.105.1.1.1.3.5.41
payload_on: 1
payload_off: 2

Is it possible to read the power consumption per port through SNMP?

Did you have to do anything special to get it to register? I have a C3750 (WS-C3750-48PS-S) and a TP-Link splitter (TL-POE200B) but it's not recognised.... everything else I plugged in with POE just worked.... Treating the whole thing as a massive set of remotely controllable on/off switches via SNMP is a brilliant idea, didn't think of that before....

So have you switched from using OpenHAB to Home Assistant?
