TWCManager
Self-hostedMake a Tesla Wall Connector follow solar output
TWCManager adjusts Gen 2 Wall Connectors over RS485 from a Linux computer. Gen 3 uses Neurio meter emulation and a separate RS485 adapter. It can follow solar generation, apply charging schedules and keep local charging records with a web interface.
Setup adds serial wiring inside the charger's enclosure, next to mains components, so the project calls for isolation and competent electrical installation. Local charger control does not need a Tesla account. Optional Tesla vehicle control adds separate Fleet API or Bluetooth requirements, and Fleet API calls can incur charges.
