  what():  stoi

I do not have any extra hardware sensor attached within the SonOff / NSPanel. Not sure if that creates the problem ??
Also perhaps it does not acceps "1,65" with "," as a number...?? and also not a negative number??? like "-3.4" or "-3,4"
???

Furthermore in sqlite file, web_nspanelsettings table. 4 new values have been added with NULL values in it:

button1_relay_lower_temperature      NULL
button1_relay_upper_temperature     NULL
button2_relay_lower_temperature     NULL
button2_relay_upper_temperature    NULL

Environment info (please complete the following information):

• NSPanelManager version: 2.0-devel branch
• NSPanel Firmware version: 0.3.767

Hey, thanks for reporting back. Are you running the devel branch or beta? Shouldn't matter any way. I can't replicate this but value do you actually have set? Is it "-3.4" or "-3,4"? I can see there being an issue with the comma and not the dot. For my region I can't set a comma in that field.
