### 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!

##### Rolling - (2021-07-03)
|
|
|
|
* Parameter `MaxRateValue` individual for each number
|
|
* BugFix: MQTT server tried to connect even in case it was disabled
|
|
|
|
##### Rolling - (2021-07-01)
|
|
|
|
* NEW FEATURE: adding support for more than 1 number on a meter (e.g. two different power readings)
|
|
Therefore the concept of "Numbers" is implemented - a bunch of digits and analog counters are combined to one number. You can define them during setup of digital and analog ROIs:

|

|
|
|
|
* MQTT: standardization of the naming - only the main topic needs to be specified. The subtopics will be named automatically. This is necessary to handle the multi number option.
|
|
**ATTENTION**: the parameter `maintopic` needs to be set
|
|
|
|
* Remark:
|
|
|
|
* This is an early stage - do only use it on a test system and make a backup of your configuration.
|
|
* The documentation is not updated yet.
|
|
|
|
* <span style="color: red;">**ATTENTION: the configuration and prevalue files are modified automatically and will not be backward compatible!**</span>
