I would like to know if Tektelic have mobile Apps for android. Most of it require manually install APK, not from android playstore, but for iOS

i have one caccount with 1 gateway and 1 sensor, however once i login to this apps, it require me to scan the gw. but end up failure. I have no idea if i see the correct apps, but it does mention tektelic. 

Also second thing,

tektelic sensor PIR (have water leak detection) - does it able to monitor FM200 too? How do i link with FM200?
