EmonEVSE is a fully open-source WiFi connected charging station (EVSE: Electric Vehicle Supply Equipment), developed by OpenEnergyMonitor in partnership with OpenEVSE.

The EmonEVSE has been designed for the European market with IEC 60947-5 (type 2) socket and 32A single or three-phase support. The unit is fully CE certified and is fully assembled and tested in the UK. 

Hardware Features 

  • 32A @ 240V
  • Singe-phase 7kW or Three-phase 22kW* (optional)
  • IEC 60947-5 (type 2) Mennekes Socket
  • Variable charge rate: 6A-32A (in 1A resolution) 
  • Status RGB LCD display 
  • Integrated power monitoring: session & all-time
  • Session controls: time limit, energy limit (KWh limit)
  • Charging timer delay schedule
  • Control via RAPI serial API
  • OpenEVSE Controller 
  • IP44 Weatherproof
  • CE certified
  • OLEV Homecharge Scheme grant approved (up to £500 discount in UK) 
  • BS EN 61851-1:2011

See EmonEVSE Datasheet for further details

Software Features

WiFi Interface Live Demo: https://openevse.openenergymonitor.org

  • Web UI Control Interface. 
  • Eco mode: automatically adjust charging rate depending on available power e.g. Solar PV diversion**
  • Emoncms data logging
  • MQTT control & data logging
  • Remote control via HTTP & MQTT RAPI API
  • WiFi OTA firmware updating


EmonEVSE units have been designed to exceed the safety requirements for EV Charging Stations from SAE J1772 and BS EN 61851-1-2011. Before supplying power to the car (and continuously while charging) the EVSE unit conducts a number of checks, no power is supplied until all the checks have passed.

  • Power interlock
  • Pilot signal
  • Ground monitoring
  • Ground fault interrupt
  • Welded contact detection 
  • Temperature throttling
  • EV ID check 
  • Ventilation check 



* Note: due to hardware limitation three-phase EmonEVSE will always calculate energy (kWh) assuming all 3-phases are being used. E.g. if a single phase EV is connected to a 3-phase unit (e.g Nissan LEAF) the LCD will calculate energy delivered as if the EV was charging using 3-phase. Charging function is not effected. To avoid incorrectly calculated energy display we recomend only charging three-phase enabled EV's (e.g. Tesla, Zoe, BMW i3) from three-phase EmonEVSE's .

** Solar PV divert requires emonPi solar PV monitor (or another MQTT solar PV data source). See EmonEVSE WiFi setup guide



EmonEVSE should be installed by a certified electrician following local code of practice: UK EVSE IET code of practice: PSEV002P

To obtain OLEV grant (currently up to £500, UK only) the EmonEVSE must be installed by an accredited OLEV installer. See UK directory of OLEV accredited installers: Download from gov website or view interactive map.


Our recomend installer is EcoPlugg. They install nationwide. Please contact them for an installation quote. 




We also work with Justin Bucknell Electrical who install around Bicester, Oxford, Thame and the surrounding areas.
