Yes, the Clock probably goes down to ~600 Mhz where with a 5 Volt at Homey’s CPU self it will run most of the time 1500Mhz. (And that low frequency slows down Homey ~ 2 to 2,5 times )
Bad Cables or connectors drop easily 0,15 to 0,25 Volt (Shows a USB Analyzer)
If a USB (A or C) provides ~5.25 Volt at max 10 Watt (~ 1800- 2000mA) that still provides 5.01 Volt at Homey internal. (at the CM4 module)
Homey doesn’t need more than ~ 0,85 A for 98% of the time (Shows the USB Analyzer…) even with the Ethernet Adapter. So everything higher rated than 10 Watt isn’t functional. Only during a Restart I have seen a short ~ 1.090 A less than 5 seconds.
