[BUG] Modbus connector doesn't support multiple slaves corresponding to the same Thingsboard device #952

Closed ferguscan closed 2 years ago

ferguscan commented 2 years ago

Describe the bug I want to have multiple Modbus slave entries for the same Thingsboard device (i.e. same device name). This would, for example, allow me to poll different sets of Modbus registers at different rates.

When I try to do this, TB receives data from only one of the slaves.

Connector name (If bug in the some connector): Modbus

Error traceback (If available): None. It fails silently.

Versions (please complete the following information): TB Gateway official Docker image 3.0.1
