It has 1k installs sharing analytics, needs the vendor's cloud and was last updated October 27, 2026. Alpha ESS reads energy generation, storage and usage data from Alpha ESS systems through the vendor's Open API. It depends on the vendor's cloud, so an AppID and AppSecret from the Alpha ESS developer portal are entered in the Home Assistant interface, with an option to verify the SSL certificate. It adds binary sensors, buttons, numbers, sensors, switches and time entities, including status sensors for the EV charger, TCP, Ethernet, 4G and WiFi connections. Polling can run on a single interval or in an alternate mode that refreshes live power data faster than summary, energy and config data. Charge and discharge schedules are handled through the periodic schedule API, with older fixed-slot endpoints used as a backup when permission is missing. An option can assume scheduled charging and discharging are enabled when their state is unknown, which helps systems that report both schedule flags as 0.

[Get in touch](https://vulpo.app/contact) [Open in My Home Assistant](https://my.home-assistant.io/redirect/hacs_repository/?owner=CharlesGillanders&repository=homeassistant-alphaESS&category=integration) On Home Assistant 2026.11 or newer? [Open it in the Marketplace](https://my.home-assistant.io/redirect/marketplace_repository/?owner=CharlesGillanders&repository=homeassistant-alphaESS&category=integration) ## Supports - **Uses the vendor's cloud**: Needs an internet connection and an account with the vendor. - **From the Marketplace**: Installed through the Marketplace, formerly HACS. - **Actively maintained**: Its author released or pushed a change in the last six months. ## Setting it up Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services. ### Connect - **AppID** - **AppSecret** - **Verify SSL Certificate** ### Reauthenticate Alpha ESS - **AppSecret** ### After setup - **Verify SSL Certificate** - **Full poll interval (seconds)**: Interval for all data: summary, energy, config, and power. When alt polling mode is enabled this becomes the slow/full poll interval. - **Alt polling mode (split fast/slow)**: When enabled, live power data (SOC, PV, grid, battery, load) polls at the fast interval, while summary, energy, and config data polls at the full poll interval. - **Fast poll interval (seconds)**: Interval for live power data when alt polling mode is enabled. Default 15 seconds. - **Assume scheduled charging and discharging are enabled when unknown**: Some systems (UK/EU) report both schedule flags as 0 whatever the app shows, so Home Assistant has no record of them until the Scheduled Charging and Scheduled Discharging switches have been set once, and every service call or duration button is refused until then. Turn this on to send 1 for any flag Home Assistant has no record of; a switch you have set always wins, and the pair is recorded once a write succeeds. Leave it off if either schedule is meant to stay off in the app. Texts from the code of [CharlesGillanders/homeassistant-alphaESS](https://github.com/CharlesGillanders/homeassistant-alphaESS). ## Entities - **Sensors**: EV Charger Status, TCP Status, Ethernet Status, 4G Status, WiFi Status ## Troubleshooting - **Diagnostics**: Downloads a diagnostics file to attach to a bug report. ## From the README > Monitor your energy generation, storage, usage data and electric vehicle using the official Open API from Alpha ESS > > Requires Home Assistant 2026.9.0 or newer.
