tesla wall connector gen 3 adapter for ioBroker

Dokumentation DE Documentation EN

Targeted at the Tesla Wall Connector Gen 3 available at https://shop.tesla.com/de_de/product/gen-3-wall-connector . Only provides read access to API data (write isn't supported by the API).

Setup

Additional to the adapter installation you have to add an instance of the adapter.

ioBroker

1. Open your ioBroker interface in a browser (eg: 192.168.178.42:8081) (if configuration dialogue was opened automatically after installation, skip to 4.).
2. Navigate to Tab "Instances"
3. Click on the wrench symbol of the Tesla Wall Connector Gen 3 adapter
4. Now you can see the main settings of the adapter configuration page. 4.1 Type in the IP-address of your Tesla Wall Connector Gen 3 (FQDN is also possible if you have a working local DNS). 4.2 You can change the polling interval, too. (Default: 10 seconds) 4.3 If your network requires a higher timeout for requests sent to Tesla Wall Connector Gen 3, please change the Request-Timeout in miliseconds accordingly. (Default: 5000 miliseconds) 4.4 In case there is an issue communicating with Tesla Wall Connector Gen 3 the adapter will retry several times. You can adjust how often it will try to read from Tesla Wall Connector Gen 3. (Default: 10) 4.5 To space retries apart a bit more you can adjust the Polling Retry Factor. (Default: 2) Example: Using default settings the 1st retry will happen 20 seconds after the initial try, the 2nd will happen 40 seconds after the 2nd try. After each successful connect to Tesla Wall Connector Gen 3, the number of retries is reset.
5. Click on Save & Close

Usage

All states of this adapter are read-only. The adapter polls the following API endpoints and creates states for each value returned.

For detailed state documentation see: Documentation EN | Dokumentation DE

Channels

info

• info.connection (boolean) - true if the adapter is connected to the Tesla Wall Connector Gen 3.

vitals

Live operational data. Key states: evse_state (charging state), vehicle_connected, vehicle_current_a, session_energy_wh, session_s, power_w (calculated charging power), currentA_a/currentB_a/currentC_a (per-phase current), voltageA_v/voltageB_v/voltageC_v (per-phase voltage), grid_v, grid_hz, and temperatures.

EVSE State codes:

| Code | Meaning | |:----:|:--------| | 0 | Booting | | 1 | Idle | | 2 | Connected but not ready | | 4 | Connected and ready | | 6 | Vehicle plugged in and handshaking | | 8 | Charging completed/interrupted | | 9 | Ready for charging but waiting on car | | 10 | Charging with reduced power | | 11 | Charging full power (3 phases, 16 amps each) |

lifetime

Cumulative statistics: energy_wh, charge_starts, charging_time_s, uptime_s, contactor_cycles, connector_cycles, alert_count.

version

Firmware and hardware identification: firmware_version, serial_number, part_number, plus IEEE 1547 CRC checksums depending on firmware version.

wifi_status

WiFi connection status: wifi_connected, internet, wifi_ssid, wifi_infra_ip, wifi_mac, wifi_signal_strength, wifi_rssi, wifi_snr.

The adapter dynamically creates states for all values returned by the API. Additional states may appear depending on firmware version.
