There is a perfectly serviceable rest API available which I am using to fully remote control my Hive Heating within my MQTT mSB.
BG haven't documented this and I suspect, don't support or maintain it, but it works well. http://www.smartofthehome.com/2016/05/hive-rest-api-v6/
A very kind person has also captured the methods in POSTMAN which makes API discovery and testing straightforward and also provides code snippets in just about any programming language or scripting you would want.
