Ohme Home Pro blue lightwhat it means
Blue on a Home Pro is delayed charging: the car is plugged in and Ohme is waiting for the scheduled or off-peak window. Solid green is plugged in, fading green is charging.
Before you start
What this means
The blue light is the Home Pro state that generates the most needless worry, because it looks like nothing is happening and that is exactly what Ohme intend. Their decoder gives blue as delayed charging: not currently charging due to a scheduled delay, for example waiting to make the most of your off-peak electricity. An Ohme on a smart tariff or a schedule will sit blue from the moment you plug in until the cheap window opens, then go to green fading in and out for active charging, then to no light when it has finished or been unplugged.
Solid green is the fourth state, car plugged in but not drawing power, which is the car being full, the car holding off, or the session between two charging windows. None of the four is a fault; the Home Pro’s only fault colour is red. The screen fills in the detail the light cannot. A plugged-in Home Pro shows Smart Charging in the top left with the charge added so far, the target and the end time, so a blue light with a target you did not choose or an end time that is wrong is a schedule to change in the app, not a charger to reset.
If you need the car now, Ohme’s Max Charge button overrides the schedule and the screen turns red to show it. What blue is not is the charger being offline. A Home Pro that has lost its connection shows Connecting to the internet, Scanning cell towers or Trying to reconnect on the screen, and that is a different page.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Waiting for a scheduled or off-peak window | Ohme’s stated meaning. The charge has been planned to run when electricity is cheapest, and blue is the wait. | Common |
| A target or ready-by time that does not need charging yet | Ohme schedules backwards from the ready-by time and the amount needed, so a small top-up may not start until the small hours even without a tariff. | Common |
| A smart tariff paired to the car rather than to Ohme | Two schedulers disagree and the charger waits for a window the tariff never grants it. Ohme describe this on their Suspended EV troubleshooting page. | Occasional |
What to try yourself
Look at the screen. Smart Charging with a target and an end time means the delay is planned, and the end time tells you when it will be done.
If you need the car sooner, press Max Charge on the charger or in the app. Ohme say the screen turns from blue to red to show it, and the unit charges as quickly as possible until full or unplugged.
If the end time is wrong every day, change the ready-by time or the schedule in the app rather than overriding each session.
If blue never becomes green even after the off-peak window has opened, check the app for a charging error or a Suspended EV notification, which point at the car’s own settings.
Get a registered electrician to look at your Ohme ev charger
We do not pass enquiries to a repair firm, so there is no form here. When you book a registered electrician, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.
