# Wiki # Project description This project has the aim to reversee engineer the H-Link Protocol used in Hisense Therma units in order to gain direct control of the machines and not relying on Hisense cloud platform. An Home Assistant custom component will be developed too. ## System description Hisense Hi-Therma lineup is composed of both monoblock and split heatpumps. The unit I have under test is a 8kW monoblock type AHZ-080HCDS1.  ## Communication interfaces There are 2 HBS interfaces available. One is used with the communication with the master controller ( Indoor display ) and the other one is used for the communication between outdoor/indoor unit (in my case they are both outdoor) and remote control with the auxilliary Hi-mit II remote controller (HCCS-H64H2C1M). Both can be found at CNx of PCB1 and they are routed differently between the monoblock/split units.
