Homevolt is a home battery launched by Tibber and Polarium, with Polarium supplying the battery technology and Tibber the software. It is sold in Sweden and Norway, with Germany and the Netherlands named as later markets, and it is controlled through the Tibber app, which optimises charging against electricity prices.
Homevolt connects over Wi-Fi, with a built-in LTE connection as a backup, and is managed through Tibber's own cloud and app. For home automation, the battery has a local web server that Home Assistant can read, but access has to be enabled on the device and Tibber's documentation points to its customer support for that.
That suits households that want a battery managed by Tibber's price optimisation and who may add Home Assistant for monitoring. It is weaker if you want voice assistants, Matter or a fully documented local API: we found none of the first two, and the local API is described mostly by community members rather than by Tibber.

What can be connected
Battery Home battery modules of 6.6 kWh or 13.3 kWh with a built-in inverter
Energy management Price-based charging and discharging, solar optimisation and paid grid support through the Tibber app
Other Tibber products Works with Tibber-compatible EV chargers and Nibe heat pumps, and with several solar inverter brands
Tibber's main app, published by Tibber AS. Tibber's support pages say Homevolt is controlled through it, and the Swedish product page says it shows real-time charge and lets the owner switch between self-produced and stored electricity. The App Store description does not mention Homevolt, and we found no separate Homevolt app. Price optimisation needs an hourly-rate Tibber contract.
A Homey community thread from 2024 reports that the inverter has Modbus but may not expose it outside the device, and no register documentation was available. We found no Tibber page confirming Modbus.
No Matter support found on Tibber's pages or in the Home Assistant documentation.

Tibber app and integrations
Official
Homevolt is integrated with the Tibber app, which shows what the battery is doing or planning. The Swedish page lists Zaptec, Easee and Nibe as compatible if they are Tibber-compatible, and says Homevolt works without Tibber communication otherwise. Owners do not need a Tibber contract to use the battery, but price optimisation needs an hourly-rate one.
A built-in Homevolt integration reads local data from the battery with no cloud. It exposes power, energy, voltage, temperature and battery percentage, plus a local mode switch, battery mode select (idle, inverter charge or discharge, frequency reserve, solar charge) and power and grid limit setpoints. It was introduced in Home Assistant 2026.3 and is listed as maintained by community contributors, and we could not confirm any vendor role. The device must have API access enabled, which the page says requires contacting Tibber customer support.
Two community options predate or extend the built-in one: a custom integration reading the battery's web server, and Homevolt4HA, a HACS custom integration with more entities including CT clamps and schedules. A separate forum package uses REST sensors against the local web server.
The Homevolt app on Homey's store is by an independent developer and states it is not affiliated with Homevolt, Tibber or Polarium. It covers the battery, a grid sensor and a solar panel over LAN, with Flow cards for charge and discharge scheduling. It relies on an unofficial API and the local web server without a password. The listing shows Homey Cloud and Pro but also says each device requires a Homey Bridge, so which applies is unclear. A 2024 community post said Athom was in contact with Tibber about support.
The battery has a local web server that can be enabled on the device itself. Community members document JSON endpoints for status, energy management data and the schedule. Tibber's pages describe an open API, and its Swedish page said it would arrive later in 2025, but we could not find Tibber's own API documentation.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
