About us
H&IT Hausautomation & Industrietechnik GmbH was founded in Berlin in 1992 as an engineering office executing automation projects. The company supplies components and systems for energy data acquisition, including MID/PTB-certified energy meters, multifunction displays, meter hubs, modems and software. In-house product developments such as the web-based meter hub HIT-WZZ100, the MODBUS-TCP interfaces HITenergy2scada and HITlog2send, and the gateway module HIT-ZGM01 round out the portfolio. The service offering also includes custom meter distribution boards and distribution cabinets, including special cabinets for offshore applications, PLC controls (ABB AC500), EEG §6 circuits, measurements and analyses in mixed-park installations, as well as planning, installation and commissioning of complete systems. Customers include industrial companies, grid operators, direct marketers and operators of renewable energy installations such as Nordex and Vestas. Since 2018, the company has provided information on smart grid topics in its own brochure.
