[Observium] "reset limits" doesn't work with one switch

Hi everyone,

I have a problem with the "reset limits" function: On a device with many sensors (305) I can't recalculate the limits using "reset limits" in the device-preferences.

Normally a note with the message appears: "Reset limits for Current sensor foo"; they will be recalculated on the next discovery run."

But with this device this message does not appear. Of course I don't know if it has to do with the number of sensors but it is the only device where the problem occurs.

Can I reset the limit values directly via the database?

Thanks! Helge
