Known Issues

• slow response of web server during picture analysis
• spontaneous reboots (mostly due to html access during image processing) - self recovery implemented

General remark: Beside the firmware.bin, typically also the content of /html needs to be updated!

8.4.0 - Multi Meter Support (2021-09-25)

• License change (remove MIT license, remark see below)

• html: show hostname in title and main page
