Tesla Wall Connector Monitor v1.1

A read-only telemetry driver for the Tesla Wall Connector (Gen 3). It turns each charger's local network data into RTI variables and events you can put on a panel: live charging status, power draw, energy delivered, temperatures, lifetime totals, and whole-site "Green Dashboard" aggregates. Monitor up to 8 chargers from a single driver instance.

Please read first - what this driver is and is not

· Read-only. This driver monitors your Tesla Wall Connector. It does not start, stop, or adjust charging - Tesla provides no local way to control the charger, so no control is possible from RTI.

Charger-side data only. The Wall Connector reports its own state (charging, power, energy, temperature) but cannot read the car's battery percentage - only the car knows true "100%." The Charging Complete event/variable means the session finished while the car was still plugged in (the practical "it's done" signal), not a battery reading.

Uses Tesla's local network API. Tesla does not publish or guarantee this interface and may change it in a future charger firmware update. Verify full functionality on your charger during the free 120-minute trial before purchasing.

Requirements

· Tesla Wall Connector (Gen 3) connected to your network over Wi-Fi (the screenless models and older generations may not expose the local API).

Each charger reachable on the LAN from the RTI processor.

A DHCP reservation for every charger so its IP address never changes. Tesla advertises itself as `TeslaWallConnector-xxxx.local`, but RTI cannot resolve `.local` names - so the driver uses the IP address.

Setup

· Add the driver to your project.

In Driver Properties > Chargers, set Number of Chargers to how many you want to monitor. Each charger reveals its own IP and Name fields as you raise the number.

For each charger, enter its IP Address (e.g. `192.168.1.50`) and a friendly Name (e.g. `Garage`, `Driveway`, `Guest`). The name is used when you assign the charger as a source in a room.

Optionally adjust the Polling intervals. Defaults (5-second live status, 60-second lifetime totals) are good for most installs. Polls are staggered so only one request is in flight at a time - light on the processor even with several chargers.

Leave Licence Key blank to use the 120-minute trial, or paste your key after purchase.

What you get

For each charger: Status (Charging / Connected, not charging / No vehicle / Fault / Offline), Charging, Vehicle Connected, Session Energy, Session Time, Power (kW), Current, Grid Voltage/Frequency, Handle/PCBA/MCU temperatures, Thermal Warning, Faulted + Alert text, plus lifetime totals (energy, charge starts, connector & contactor cycles) and device info (firmware, serial).

For the whole site (Green Dashboard): Total Power, Total Session Energy, Total Lifetime Energy, Charging Count, Online Count, Any Charging, Any Fault.

Events fire on every change: per charger - vehicle connected/disconnected, charging started/stopped, charging complete, fault/cleared, over-temperature, online/offline; site-wide - any charging started, all charging stopped, any fault.

Ideas for your design

· Green Dashboard: graph `Site Total Power kW` and per-charger `Power kW`, show `Site Total Lifetime kWh` as a running energy counter.

Charge-complete announcement: trigger a macro on the `Charger 1 Charging Complete` event to drive your Announcer driver - e.g. "Tesla is fully charged." It fires only when charging finishes while the car is still plugged in (not on an unplug or a fault). Use `Charging Stopped` instead if you want *every* stop.

Over-temperature alert: the Gen 3 is known to run warm under load - bind a macro to `Charger 1 Over Temperature` for an early heads-up.

Presence/automation: use `Charger 1 Vehicle Connected` to know when a car is plugged in.

Licensing

One licence covers every charger on this processor - monitor a whole property of Wall Connectors with a single purchase. A 120-minute cumulative trial is included so you can fully test before buying.

Troubleshooting

· A charger shows Offline: confirm its IP is correct and reachable (ping it), and that it's the display Gen 3 model on Wi-Fi. Confirm the DHCP reservation is in place.

Status never updates: verify the IP, then try Refresh State or Force Reconnect.

Values look wrong after a Tesla firmware update: the local API is unofficial; contact support and we'll investigate.
