Unexpected exception when adding Calex contact sensor

[smithbill17]

When I try to manually add a Calex contact sensor device (automatic detection doesn't find it even though its in SmartLife and working and the device is Tuya capable), i get this exception error:

The sensors are not yet supported in this integration, only the devices that supports full time connections. The sensors as, contact or PIR only connects to wifi when value changes and so the integration is not able to connect to them.
