Thank you Borpin, I have exported all Emoncms data of old SD card (following backup procedure) and I have performed a fresh installation of emoncms on a new SD card
Now app and services are running as expected. But I have just one issue after do the process. My system has emonPi + emonTx V3 and EmonTx does not report any input… I have not clear what is the process to restart it or reconfigure, any clue?
Thanks for everyone for your support!
