A smart charger that shows as offline in its app usually has a connectivity problem, not a charging fault. Since 2022, UK home chargers have had to work when offline too, so many will still charge when you plug in, just without scheduling or app features.
Start with the basics: check your router is working and that the charger is within a good Wi-Fi range, since a charger fitted on an outside wall or in a garage may be at the edge of coverage. If you've recently changed your router, name or password, the charger will need to be reconnected to the new network.
Then try restarting the charger through its app or by switching its circuit off and on at the consumer unit, and check whether the app or the charger firmware has an update pending. A Wi-Fi extender or mesh node near the charger can fix persistent weak-signal problems.
If the charger still won't connect, or any charging or tripping issues come with it, contact the installer or a qualified electrician. Tell us about it in the quote form and we'll help match you with someone local.
