DH not working on any Xiaomi sensors

Hey. Not sure if anyone else has encountered this issue as it’s frustrating. I have the Xiaomi aqaura water sensor. I added a custom dh but I put the sensor in water and doesn’t work. When I try the smartsense water sensor it works fine. I have had zero problems discovering the device and adding it manually. I also have the same problem with Xiaomi temp\humidity sensor as it works find with the smartsense temp handler. I have left the devices with custom dh for 48hrs but the hub is unable to ping them and stay offline. Anyone else encountering this issue?
