Tesla Battery Plugin for Indigo Domo

Connect your Tesla Powerwall to Indigo Domo for live monitoring, automation, and control — entirely from your local network, with optional Tesla cloud features.

Changelog

1.0.35 — 2026-06-18

- Fixed 403 Forbidden errors from Tesla Owner API caused by Tesla enforcing TLS 1.3 - Added TLSAdapter to bundled teslapy library — pins all HTTPS connections to TLS 1.3 only - Fix is equivalent to teslapy PR #176 (merged 2026-06-15, not yet in a release) - Removed battery_list() debug call from getauthTokenOnline() that crashed the background thread on every loop restart - getsiteInfo() now returns "" on exception (previously returned None, causing callers to misread failure as success) - getsiteInfo() logs a clear human-readable message on 403 rather than a stack trace

1.0.30 — 2026-05-31

• Add comprehensive wiki documentation
• Update README with banner, feature table, wiki links, and inline images

1.0.27 — 2026-05-31

• Fixed TariffResolver exceptions crashing runConcurrentThread — now caught and logged gracefully
• Fixed grid fault trigger never firing on first fault appearance (condition was inverted)
• Fixed grid fault log message showing "BLANK" when faults were present
• Fixed get_tariff_rates_online unbound dev variable when no battery devices exist
• Fixed setOperationalModeOnline TypeError on auth failure (datareturned is always None)
• Fixed JSON string injection in sendcommand local login payload — replaced with json.dumps()
• Fixed battery level image not updating at exactly 25% charge
• Fixed SystemIslandedReady grid state not handled — now treated same as SystemIslandedActive
• Fixed fillmetersinfo exception handler logging wrong function name (fillsiteinfo)
• Fixed OAuth if not self.tesla.authorized: guard (was commented out) — prevents unnecessary token refresh on every call
• Removed discarded getsiteInfoOnline() call in setOperationalModeOnline
• Removed TypeError-causing 'authorization_required' in datareturned check
• Changed bare macOS version info log to debug

What Gets Created

After running Generate Devices, four devices appear in the Tesla Battery Gateway folder:

Powerwall Images

The plugin includes 500+ images for use in Indigo control pages — charge level images (1–100%), combined state + charge images for all three states (charging / idle / discharging), and flow indicator icons.

Charging 50%	Idle 50%	Discharging 75%

The batteryState_combined device state (e.g. charging_73) maps directly to these filenames. See the Control Pages wiki page for setup instructions.

Requirements

• Tesla Powerwall with Gateway on your local network
• Indigo Domo 2022.1 or later
• Python 3.10+ (bundled with Indigo)
• Static/reserved IP address for the Gateway
• (Online features) Tesla account + Refresh Token

Support

• Wiki — full documentation
• Issues — bug reports and feature requests
• Indigo Forums — community discussion

Changelog:

Add Control Panel Images to github for usage Add Battery Charging State Add Grid Usage T/F State for Image selection Add kW to all given production/consumption/usage data Change to PluginStore Update Code

A Plugin for Tesla Battery Gateway - enabling you to see everything that is happening within the Tesla App, and even re-create the app on a Indigo Control Panel (images are provided to help)

eg. Grid Usage in Watts & kW Solar Generation in Watts & kW Battery Usage in Watts & kW Home Consumption in Watts & kW Grid Usage T/G Battery Charging T/F

Also informs you in Connected to Grid - so in case of Grid outages can run Action Groups - eg. turn off devices.

Further Documentation to follow - but these pictures should explain

Usage

1. Need Tesla Battery with standard Gateway

2. Set up Static IP Address for this Gateway on the same network as Indigo Server

3. Install Plugin from

https://github.com/Ghawken/TeslaBatteryPlugin/releases/

1. Go to Plugin Config - enter the Gateway IP Address

Click the Check Connection Button

If communicating - Generate Devices button will appear Click the Generate Devices button

This will create the plugins four devices with a folder called 'Tesla Battery Gateway'

eg.
