Sensor value to use in pages.json

[sbruynin2340]

I captured a sensor value with my_custom.cpp and want to show it in a specific page on the display. Can this be done via pages.json? Can the sensor value be linked to a page / id?

You need to do this in your custom code. You can use openHASP or LVGL api's to modify the object:
check out #653

Thanks, it works. Great firmware.
I now ran into a problem: I uploaded a binary font (probably to big) and get :
Prompt > [ 3.158][102388/112452 8][19620/35488 45] LVGL: Couldn't allocate memory
Prompt > [ 3.168][102388/112516 9][19620/35488 45] LVGL: lv_font_get_bitmap_fmt_txt
Prompt > [ 3.179][98292/110388 10][19620/35488 45] LVGL: Out of memory (0x00000000)
and I cannot access the webapp to delete the font file. Any other way that gives access to the filesystem?

I solved the memory problem by increasing LV_MEM_SIZE and LV_VDB_SIZE in include/user_config_override.
Access to the webapp was possible again and then delete the large fontfile using the file editor.
Thanks anyway for your help.
