Powering technology via POE
Since moving to a UNIFI network setup, I have had an unhealthy obsession with POE (Power over Ethernet).
Fort the last 3 odd months, I have been slowly converting devices in my home into devices that can and are powered over an ethernet cable by connecting to my Unifi system.
What are the benefits for me?
Smarts hubs are a necessary evil if one wants any kind of smart home technology. These hubs are powered via micro usb cable, or a USB C cable or the worse imaginable kind is the DC power brink. The worst offender is the Philips Hue hub.
Powering these smart hubs over over ethernet has the following benefits:
- Since every one of these hubs are now powered by my Unifi system, these hubs also benefit from the UPS backup power supply that protects my Unifi system during power outages or surges. For example, if the power goes off for a few seconds, my Unifi system and my Synology NAS is unaffected. The devices that are connected via POE to my Unifi system are also unaffected and are protected. Most importantly, these devices continue to function.
- Cable management: removing the need to be separately powered because one cable is providing both power and data is just a much cleaner setup. This was my primary reason for opting for POE. In a strange way, a clean setup always makes me feel good.
- Power strips: we all have power strips located everywhere in the house and each device that is powered over ethernet is taking one less outlet on my power strip and I like that.
Which devices in my home use ethernet for power?
- Two Unifi Floodlights
- Five Unifi cameras
- Two Philip Hue Hubs
- 1 x Aqara Hub 2
- 1 x Ikea Dirigera Hub
- 1 x Grandstream HT802 (VOIP for my landline)
Where a device does not natively support POE like the Aqara hubs, these adapters are required:
Philip Hue Hub
These were the most cumbersome to convert because they are using the old school brick. Essentially, upgrading these roughly cost me AUD26. You need:
- ANVISION 5V PoE Splitter, 48V to 5V 2.4A
- 5.5mmx2.1mm Female Socket to 5.5mmx2.5mm Male Plug Jack DC Power Adapter
At the time of writing, I have six vacant POE ports on my UniFi system. Unfortunately, I have no other devices in my home that I can convert to POE. This means I have officially successfully completed Project POE.
