- For
- Owners and operators of EV charging equipment
- Worth noticing
- OpenEVSE discovers chargers with mDNS and serves the charger’s own web interface over the local network.
Field notes
OpenEVSE and Overwatt represent two distinct operating models for EV charging software. OpenEVSE discovers equipment with mDNS and works through the charger’s local web interface, avoiding both accounts and cloud infrastructure. Overwatt instead stores charging data through a cloud-backed account. The homepage also identifies Robert Rankin as the direct contact for support, privacy requests, and business enquiries, giving the small company a clear human operating point.
