Tehama was founded in 2003, but its core engineering team has worked together for more than 30 years. Its hardware has been in the field since 2004, remotely monitoring temperature and other environmental data in the healthcare and food service industries. In 2010, the company introduced its second generation hardware and software, which has since grown to become the widest selection of wireless utility submetering products, all of which are made entirely in the United States.
