Open Source Load and Air Conditioning Controller (O.S.L.A.C)

RER was developing a business facing demand response product from 2017 to 2020. The product was aimed at Australian Gentailers and Retailers.


The three product hardware variants were developed:


RER Flex - Air Conditioner (DRED)

RER Flex - Pool Pump

RER Flex - Hot Water

After almost 3 years of development the decision was made to Open Source the project in the hope that 'makers' and companies can leverage this technology to increase renewable energy usage. The Open Source project is offered under an MIT licence, such that anyone can build upon the low cost and flexible concept.
