<p>Hallo,</p>
<p>ich betreibe seit gut einem Jahr eine Volkszähler-Installation
auf einem Raspberry Pi 3 mit dem Image
2018-03-27-vz-raspbian-stretch-lite. <br>
Neben den Verbrauchsdaten eines EHZ (PV-Einspeisung und Bezug) und
eines Ferrraris-Zählers (PV-Erzeugung) erfasse ich auch mit
einigen Temperatursensoren (über ESP 8266) Temperaturverläufe.</p>
<p>Ich möchte nun auch (insbesondere für die PV) mit virtuellen
Kanälen arbeiten, was diese Version aber nicht unterstützt.<br>
<br>
Wie kann ich möglichst sicher (also ohne Datenverlust) auf die
neue Version wechseln? Habe verscheidene Ansätze im Forum gefunden
- aber keinen kompletten.<br>
<br>
Gruß<br>
Jürgen<br>
