Well then you have a huge bag of really reliable sensors right under your nose. All you need to do is add Home Assistant, a ConBee 2 stick (or similar recommended) Zigbee controller and Home Assistant Device Bridge in-between the sensors and Hubitat. They pair in seconds and are rock solid. You would honestly spend a lot less time, frustration and money just setting up HA as a bridge for devices, than you'll spend on a bunch of new contact sensors.
As an extra reward for your minor efforts and a little bit of cash, you'll get access to a tonn of really good sensors that otherwise don't play nice when joined directly to HE. I really love the combination of the two. I hate automatons on HA, but love them on HE. I previously had a lot of trouble with Aqara, Mijia and a host of other low cost sensors on HE, but the ConBee 2 just happily pairs in seconds and doesn't let go. Only devices that still give me trouble pairing are IKEA. They stick once joined, but most of them (especially their repeater) put up a huge fight when you try to join them to either platform.
