Heatmiser integration via API

[Tokatubs]

Have a hotel complex with thermostats from Heatmiser with their Neohub in every hotel room. But i need to have signals from the thermostats over to the BMS system of the hotel. 
This is Desigo CC and therefore i was thinking of using LM5 converting the signals from the Heatmiser converting it to bacnet. 

With the API is this a realistic plan or would this be to difficult to do ?

It's doable. The protocol is rather simple - JSON data exchange via TCP on port 4242. Do you want two-way control or just to retrieve status data?

The thought was 2-way control. Read and wright setpoints and hvac.

The device should support multiple connections so the easiest way is to have a single resident script (always connected) for periodical status retrieval and several event scripts that write values to the hub (one-time connection: connect-write-disconnect).
