The LMC manages a defined group of chargers. If that group no longer matches what is physically installed, load management stops working for the affected charger — even though everything looks online and immediate charging still works.
This is the expected state after a charger has been replaced, after a new charger has been added to an existing site, and after an LMC factory reset.
How you can tell
Charging on demand works, but scheduled, price-based or solar charging does not.
The site reports a load-management configuration issue in Health Status, or the app shows a configuration notification.
The charger's details render oddly in the site view — for example a blank or implausible firmware version.
Re-attach the charger to the LMC group
Open the site in the VOOL Portal at app.vool.com.
Remove the charger from the LMC group.
Wait a moment.
Add it back to the group.
Repeat for each charger on that LMC.
The charger's details, including its firmware version, should render correctly again once it re-attaches.
Then check the control channel
A replacement charger arrives with default settings, and a reset can leave the LMC and the charger disagreeing about how they should talk to each other. If the two do not match, the charger will reject load management even with everything online. See Charger–LMC communication: CAN, LAN and control channels and Charger's OCPP Source.
A note on factory resets
A factory reset of the LMC is sometimes used to recover a lost internet connection. It works, but be aware of what else it does: it clears the LMC's settings, removes all previously configured chargers, and removes any configured Wi-Fi networks — so an LMC that was on Wi-Fi will come back with no network at all. Only reset an LMC when somebody is on site who can reconnect it.
If it does not come back
Send us the LMC serial number, the charger serial numbers, what Health Status reports, and whether the connection between them is CAN or over the local network. We can see the group from our side and put it right.
