HARDWARIO Integration
The EM111 connects to HARDWARIO devices via Modbus RTU (RS-485):
- GAUGER: The GAUGER device reads Modbus RTU registers from the EM111 and sends energy data to HARDWARIO Cloud.
- CHESTER: CHESTER with RS-485 extension module can poll the EM111 and forward data via NB-IoT or LTE-M.
