Visonic MCT-340E Sensor Pairing Trouble

Hey everyone!

I’ve got a few of the VIsonic MCT-340E sensors from MyDigitalDiscount - I’ve had great luck with three of the five sensors, but the other two are really finicky when pairing. One paired for a bit, then won’t pair anymore and the other never paired at all. The sensors go in to pairing mode, but no signs of it show up in Hassio.

Wondering if anyone else has experienced this with these sensors?

Thanks!

Just tried the same two sensors giving me trouble with a Smartthings hub and they paired immediately, so it seems to be something with Hassio.
