No question, more a hint for the Digitec team. Instead of specifying the universal USB chargers, some of which do not work, as a suitable power supply, it would be more helpful for customers if you would specify the article "16132503" (Ubiquiti U-POE-AT) for CHF 24.90. This works perfectly. It works perfectly, does not require a "block" on the connector strip which may need several slots and you only have to connect one Ethernet cable to the controller.
