Firmware-update: SmartEVSE 3.11.1

Als je zelf een laadpaal voor de elektrische auto in elkaar wilt knutselen, kun je meestal een hoop geld besparen. In dat geval heb je onder meer een controller nodig, bijvoorbeeld de opensource EVSE van fabrikant Stegen. Een randapparaat voor de SmartEVSE-controller is de Sensorbox: dit is een kastje dat de P1-telegrammen van je elektriciteitsmeter vertaalt naar modbusberichten, op basis waarvan de SmartEVSE zijn laadvermogen regelt. Voor diegenen die geen P1-aansluiting op hun elektriciteitsmeter hebben, zijn er ook aansluitingen voor CT-klemmen aanwezig op de Sensorbox.

Door een goede samenwerking tussen community en fabrikant worden de communityversies na verloop van tijd overgenomen door de fabrikant, als de stabiliteit in de community is bewezen. In versie 3.11.1 zijn de volgende veranderingen en verbeteringen aangebracht:

WARNING:

If you have sub-panel configuration, your EVMeter was used to guard MaxCircuit. Since version v3.11.0 a separate CircuitMeter can be defined, and THAT meter is used to guard MaxCircuit. EVMeter then will be used what it was intended for, to measure the number of kWh that goes into your EV. So if you have sub-panel (garage-) configuration, reconfigure your current EVMeter to the new CircuitMeter!! IF YOU DONT CHANGE THIS YOUR MAXCIRCUIT WILL NO LONGER BE GUARDED!!!
