Hi

Has anyone hard wired multiple EZMotion sensors ?

I have a few and , know they perform better powered, rather than on batteries ?

What power converter did/can i user and what sort of cabling is required or 5VDC ?

Thanks

Hey
I have done this.
I cut the tip from a normal phone charger

put a connector block on it and wired three sensors to that.
Been like that for 3 months without issue

Hi

I’m already running one myself if of a USB cable , but I’m looking to connect maybe 4-6 more.

What type of wire/cable have you used to join them together?
Is there a type/model/code of wiring I should use ?

I used 4 core alarm cable and on the upstairs ones I used cat 5

Thanks @konradwalsh

I found this on the Express Controls site (in their Vera specific .pdf)

Up to 10 EZMotions can be powered from 1 USB power supply. Each EZMotion requires 50mA. The length of the wire can be over 100ft but check the voltage drop as it must remain above +4VDC. If the wire goes near motors or other sources of electrical noise a capacitor may be used to filter the noise. Use a 100uF (or larger) capacitor right at the EZMotion pins. CAT 5 cable works fine any only 1 pair is needed.

I’m not entirely sure what they mean by “Use a 100uF (or larger) capacitor right at the EZMotion pins”

That’s handy
