I've got a few USB devices (Aeon Multisensors) that I would like to hardwire into a power source so I don't have to rely on batteries. They are designed to be hardwired and have a USB cable to do so.

Should I run power to the sensor, then use a transformer and connect up a USB plug?

Or is there something built to do this that i'm overlooking?

What i've considered doing, i have the same sensors, is running long usb cables back to a central point with a UPS and a usb powered hub plugged into that. I found those sensors work great USB powered, not so great battery powered. Well the 4in1 ones do, not sure about the newer ones.

I have one of these and agree, they are much better on USB power - but remember if you to change from batteries to USB you have to exclude and re-include the sensor in your Z-Wave network, so it can reconfigure itself as a powered node. I just use an iPhone USB wall wart to power mine.

Hmm, I don't think I could get a USB cable long enough to run them all back to one place. I could bodge up a cat6 cable perhaps.

I had considered adapting USB charging keystones but they can be expensive depending on who they are from.

pbtech have them cheaper $2.754 including gst. I just installed 8 in my house.

You can run 20m usb adaptive usb cables, so you should hopefully be able to get something.
