Shelly BluHT issue

I have a really strange issue I can’t figure out:

I have shelly blu HT temperature sensors in two separate buildings which are on the same lan tied together with unifi UBB.

Every device in both buildings show up on my local lan and have full control over with HA…except the temperature updating to HA (shelly app and cloud update normally) from battery powered shelly blu HT from building which is the station side of UBB? All shelly bt listening devices are set identical on both ap and station building.

Has anyone experienced this behavior?

Update: the Shelly BluHT+ which has Wi-Fi does not have this issue.
