Tesla has begun rolling out mobile app version 4.58.6, a release that pulls the company's energy ecosystem — Powerwall, solar, home charging and now household circuits — under a single roof called Tesla Home. The update started reaching customer devices on Monday, 7 July 2026.
Opticaster comes to the app
The headline addition is Opticaster, the AI optimization engine Tesla already uses to run its energy products behind the scenes. Surfaced in the app for the first time, Opticaster automatically decides where to source your energy from and how to use it, building custom plans around your solar generation, household consumption, utility rate plan and local conditions rather than relying on the fixed timers owners previously had to configure by hand. For a home with a Powerwall and solar, that means the system itself works out when to store energy, when to draw from the grid and when to sell back.
Smart Charging for the Wall Connector
4.58.6 also brings automated Smart Charging to the Tesla Wall Connector. The charger now runs an algorithm that reads your local electricity tariff and schedules charging for the cheapest hours — typically overnight — while making sure the car finishes its full charge before the morning rate increase.
What it means for European owners
Smart Charging is the most directly relevant piece for drivers in Europe. Time-of-use and dynamic tariffs are widespread across the continent, from the UK's Octopus Agile to Nordic day-ahead spot-price plans and Spain's regulated PVPC rate, and an automated window that tracks them can meaningfully cut the cost of home charging with no manual scheduling. Opticaster is equally useful for the growing number of European households pairing a Powerwall with rooftop solar, where the value lies in deciding minute by minute whether to charge the car, top up the battery or export to the grid. Both features work through the app that European owners already use daily, so no extra hardware is needed to benefit.
Smart Breaker control
The third confirmed feature is in-app smart breaker control. Owners with compatible smart breakers can now manage individual household circuits from the app and, crucially, designate non-essential high-draw loads — electric heaters, pool pumps, air conditioning — to shut off automatically during a grid outage. Cutting those loads lets a Powerwall stretch its stored energy much further when it matters most.
Smart breaker hardware is currently centred on the North American electrical panel, so physical availability outside the US remains limited for now; the app-side controls themselves ship with the update globally.
What's still coming
Code in the release also points to home heat pump control arriving in a future update, which would let the app manage a home's heating and cooling as another load inside the Tesla Home system. Tesla has not confirmed a date, and the feature is not live in 4.58.6.
Taken together, the three additions mark a clear step in Tesla's plan to manage a home's entire energy picture — generation, storage, charging and consumption — from one app, with Opticaster making the decisions rather than the owner.
