Hi,

Shortly after I got my first two P110s there was a firmware upgrade and associated update to the IOS App which enabled a lot more energy monitoring data. A side effect was that it completely corrupted any existing recorded data, so really the only option was to clear everything. At that time it didn't matter as I didn't have much recorded, but I would like to know whether this is expected to be the case for future updates.  As a precaution I've made sure my devices are all set not to upgrade automatically,

Thanks, NF
