• Fixed calculation for I2 combined with export (negative value) for 3w meters not reporting this value
• Improved graph y-axis range when negative values are present
• Improved WiFi disconnect to preserve power when connection is lost
• Added persistence to realtime data to make it survive a software reboot (does not survive hardware reboot)
• Added voltage monitoring and automatic WiFi disconnect on low voltage for Pow-U (To prevent brownout)
• Added option to disable 802.11b, which will improve voltage stability
• Added support for Slovenian Iskra meter

Release v2.2.21

• Fixed issue where device jumped into AP mode on WiFi outage
• Fixed problem where realtime data disappears on negative cost
• Fixed window skew on graph two hours before midnight
• Fixed y-axis range problem on graphs after leaving GUI open for a period
