Article introduction
Translation to English: Thermal monitor
Without the cloud: monitoring and controlling heating systems from Bosch, Buderus and Junkers
According to Bosch, you need a connection to the manufacturer’s cloud to evaluate and control heating systems. The open-source project EMS-ESP takes a shortcut and connects the heating system to the local network and open control centres such as Home Assistant and OpenHAB via the EMS protocol. This allows you to bridge the gap and automate your heating system.
