No. Your Smappee will temporarily save his measurements locally when he loses connection with the internet. These measurements will be sent to our servers as soon as internet connectivity is restored. How long Smappee can save these temporary measurements is determined by:
- The number of phases being measured
- Whether solar is being measured
More measurements will occupy more storage space. As soon as the local storage space is full, Smappee will discard all measurements untill the local measurements have been sent to our servers.
The average Smappee should be able to keep working as intended for up to 2 days without internet connectivity, before he starts discarding measurements.
