Do these act as nodes in the zigbee mesh?

It's Device Type: Router. It will help strengthen the mesh.

Can it actually be powered with AC 7-32 volts? I would like to power it from an unused doorbell nearby which is powered by a 24 volt transformer.

Yes,there are 2 power supply options.USB 5V or AC/DC 7-32V,any one of them is ok.

When I push the manual button or turn on through Zigbee there is no change in output voltage but second red light comes on next to the relay. Ideas?

This is a relay switch, it is either an open or closed circuit that can be a momentary or normal. There will be no power unless you somehow supply it to one side of the switch.

Can this work as a sensor?

It works as zigbee wireless button with inching mode,works as wireless switch with latching mode.And please check this zigbee contact window door sensor with asin B0B2K11LW.
