can this device be turned on or off using the phone app?...does it work with iphone?

It works with iphone. You can disable and enable the sensor's alert from the App, but it is not fully turned off, if you disabled the alert, it will not send alert message or trigger off the alarm, you still can check the history of records through the app. Thanks!

There is a delay when using this to turn on third party switch. Is there a work around?

If you use the Alexa routine to integrate third party switches, normally it should take less than 1 second when the motion is detected and the action to turn on the switch. Very few times may be delayed a couple seconds due to the network routing and Alexa cloud. If you experience high rate of the delays, please contact the technical support by emails or phone call. Thanks!

My home has 3 AirBnb rental units and each will have a motion sensor. Will the app allow me to silence 1 sensor when that unit is occupied?

Yes, with the new update that came out a couple weeks ago you can now have separate alarm strategies for each device. I use an iPhone So you could have one alarm strategy named un occupied and another named occupied. Then just change the strategy for the one(s) that are occupied.

Would a ceiling fan set the motion sensor off, making it signal that there is motion in room, even though no person is in room?

I have several in my house, garage and barn. The one at the front door sends notification of visitors and turns on lights. The one in the barn just turns on two sets of lights. These sensors have different levels of sensitivity settings that I had to experiment with to get it to works the way I wanted it to. Try one and if the fan sets it off try moving it or adjusting the sensitivity levels. You will also need a YoLink hub for all you sensors and switches. Good luck.
