Three paths to a charger on your wall.
Build it from open-source plans. Buy our pre-built version of the same plans. Or pick a vetted commercial unit from a partner. No subscriptions, no cloud lock-in, no monthly fees on any of them.
Open-Source DIY EVSE
ESP32-based Level 2 EVSE you build yourself. Ships with pre-loaded firmware, full wiring diagrams, BOM, and integration guides for Home Assistant. The hard work — protocol stack, contactor control, ground-fault detection — is done. You bring the box, the wire, and the install.
T&L-Branded Build (Optional)
Same open-source platform, assembled and tested by us. For folks who want the ESP32 EVSE without sourcing 30 components. Same firmware, same documentation, same right-to-modify.
Partner-Sourced Stations
Ready-made commercial EVSE units from vetted partners — currently evaluating evsegroup.com (SAE J1772 80A Type 1 hardware). For users who want a name-brand wall unit without DIY assembly. Partnership outreach in progress.
“A charger is not a service. It's a wall outlet with a brain.— On EVSE
You shouldn't need to log in to use it.”
