Version 2.40

New in this version:

• Mains meter phase detection
• Write number of used phases into the car
• Add high resultion font
• Visualize STATE_A (EV disconnected)
• WiFi option for Sensorbox 2
• Fix alignment of currents <= -100A
• Implement state B1 & C1
• Allow Smart/Solar switch on a node
• Increase external button bounce delay
• Try to broadcast communication error to Nodes
• Stabilize balancing, especially when charging on three phases
• Allow mode change within the menu of the master controller when nodes are active
• Increase SolarStopTimer when measurement is not finished
• On automatic Phase detection pause SolarStopTimer and print "DETECT" instead of the time
• Add CAPACITY menu option to limit max current draw on MAINS (sum of phases)
• Show number of phases detected with Mains electric meter on Node
• Delay with minimum current when start solar charging
• Dynamic decimal point on kWh information
• Make StartCurrent per phase (for same behaviour on different cars)
• Stop solar charging only when over 6 A (per phase) more than StartCurrent is used

Changes incomptible to previous version

• Add Finder 7M.38.8.400.0212 electric meter
• Allow ImportCurrent to be negative (for steady export)
• Allow StartCurrent to be negative

SmartEVSE-2 v2.30

New in this version:

• Rearranged the modbus registers.
• Set modbus address 0x01 when load balancing is disabled.
• Interrupt sending modbus requests for 4 seconds when receiving requests from another device to avoid collisions.
• Added RFID EnableOne option, that will allow only the RFID card to unlock the EVSE that lock (start charge) the EVSE.
  In this mode it will lock the charging cable when connected, and only unlock the cable if the same RFID card is presented (like a public charging station)
• Allow custom meter FUNCTION config.
• Added support for WAGO electric meter and SolarEdge Inverter in SunSpec mode.

SmartEVSE-2 v2.20

SmartEVSE-2 firmware 2.20

This software version has a lot of additions, cleanups and rewrites.

• The modbus communication between SmartEVSE controllers had been rewritten. Now the master will poll each node for state changes, and act accordingly.
• The modules internal temperature is now visible in the setup menu.
• The setup menu now shows a navigation indicator, which shows how many menu options are available, and the current position in the menu.
• The broadcast address 0x00 has been moved to 0x09, as this was incompatible with some modbus kWh meters.
• The number of SmartEVSE's that can be configured in a load balancing setup, has been increased from 4 to 8.
• To use the LCD more efficiently, the text is now displayed condensed, where the i takes up less space then a w.
• Added the option to connect a one-wire RFID reader, and lock/unlock the SmartEVSE with up to 20 RFID cards.
• Added the option to use a modbus kWh meter, and show the charged energy (kWh) and power (W) on the display.
