Anyone setting up a nice smart home will probably have come into contact with PoE or Power over Ethernet. PoE is a technology that makes it possible to send and use electricity via Ethernet cables. For example, it can be used to supply WiFi access points with power. The power can be transmitted up to 100m via the LAN cable and so no additional power supply unit is required.
Supply Philips Hue Bridge via PoE splitter
To be able to supply a device via Power over Ethernet, we first need a power source. This can be a PoE-capable Ethernet switch or a PoE injector.
The Philips Hue Bridge does not have the option of being supplied via PoE, for this you need a so-called PoE splitter. This PoE splitter is suitable together with the 2.1mm to 2.5mm adapter to supply the Philips Hue Bridge. Please note that this should be version 2.0, i.e. the rectangular version.
