Indeed, for the moment Theengs focus on ble broadcaster not connection.

Thanks for the clarification. I thought it's a bug.
TheengsGateway being able to mimic the BLE functionality of OpenMQTTGateway would make it really popular. If you have some pointers about this particular case, I can give it a shot at porting it to TheengsGateway.

Thanks for proposing help, here is some pointers:

• so as to connect we can already use the model_id coming from the decoder to know if we are dealing with a HHCCJCY01HHCC,
• once identified OMG attempt a connect for the battery 1/10 times so as to avoid consuming too much battery of the device
• from this you can attempts a connection to it, the gateway uses bleak, so you can try to use this library
• once the sensor is connected, you will have to retrieve a value from a pair of service/characteristic, here is where it is done from OMG
• finally this value can be published
  This could be done as a separate process from scanning so as to don't block it, even if the data is published with only the battery.

This is definitely more than I can chew. 😁
Hopefully some of the other developers can add this feature.
