Bring on the improvements though. Let’s trim-the-fat/shed-some-weight/less-is-more this approach!

I hear you - I went on the same journey recently with WLED stuff!

I know the contact sensor one is useful though as it flips the OPEN = True mapping to the opposite of the rest

I think you can trim this down very easily already. For example, on your motion sensor, you could get rid of all the JS transforms by changing your things file as follows:

Type contact : occupancy   "Occupancy"    [ stateTopic="zigbee2mqtt/UNIQUE_ZIGBEE_ID", transformationPattern="JSONPATH:$.data.occupancy", on="true", off="false"]
Type contact : tamper      "Tamper"       [ stateTopic="zigbee2mqtt/UNIQUE_ZIGBEE_ID", transformationPattern="JSONPATH:$.data.tamper", on="true", off="false"]
Type contact : battery_low "Battery Low"  [ stateTopic="zigbee2mqtt/UNIQUE_ZIGBEE_ID", transformationPattern="JSONPATH:$.data.battery_low", on="true", off="false"]
     

The above will use the JSONPATH transform to extract the required values, then map true and false to on and off (which for a contact channel actually means true and false will map to open and closed). If you want to switch it, you can map on="false" and off="true"…

(I’ve made an assumption here on what the device actually returns on these topics, so you may need to tweak)
