POE to type C adaptor to run FP2

Hi has anyone used a POE to type C adaptor and ran the FP2 sensor ?

Just finishing a new build with a host of Aqara products but I have ethernet in the places where ideally I would like to power the sensors.

I have the FP2’s ready to go but want to know if any else else has tried this instead of running a power cable. Next option is to get more of the battery versions.

I had not personally tried it but if the poe injector you’re using can supply the necessary power for the fp2 then it should be fine. This is a great idea and would love to see how it turns out if you decide to give it a try

I’ve not tried them with the FP2 but have done with a bunch of other usb devices and not had any issues.

If you are planning to use a PoE-to-USB-C splitter (Power Delivery), you might run into issues where the device simply won’t turn on.

The Aqara FP2 appears to lack the necessary resistors on the CC (Configuration Channel) lines required by the USB-C standard. Smart power sources (like active PoE-to-USB-C adapters or PD chargers) wait for a handshake signal to release power. Since the FP2 doesn’t send this signal, the adapter assumes nothing is connected and provides 0V. The reliable workaround is using a PoE-to-USB-A splitter with the original A-to-C cable, as USB-A ports provide power without negotiation.

Here are a few threads where others have confirmed this behavior:

Thank you John,

After more research I think I will run into problems with this, unless I add an additional switch POE that allows power regardless of the "the handshake " you mentioned. I will keep all informed if I get to work.
