Are you rebooting LM via UI? If you reboot via power cycle then the latest changes might be lost.
As for you previous questions - the possibility to edit existing devices is not meant to be a replacement for the main Modbus UI. It is implemented to tweak the profile instead of making a new device from scratch if any mistakes are found. That's why proper object selection is not implemented.
If you edit custom values for an existing device nothing will happen until you map a new object via main Modbus UI.

Hmm, yeah, it was power cycled.
I had last changed the modbus profile in end of July (about same time as my previous post in this thread). After that date, I have both clicked "Save project", updated to the new beta firmware, and saved project backup (have not tried to restore, but would expect it to also be wrong then?)
The power cycling happened this weekend.
What can I do to make sure my modbus settings are not lost in case of a power outage?
Sorry, I have not been able to reproduce this (and I've tried!), so don't know what happened, but it must have been some kind of coincidence. Sorry for the noise!
Great app. Just a couple of questions.
1) I tried to set the Default value, but it seems that it is not saved.
2) I get two strange behaviors when reading the power from a solar inverter (Fronius)
If you observe, the attached picture,
a) during night time I get values of 0 or -3276.8, which I guess it has to do with the Default value
2) between 09:45-14:50, the values I get seem to be divided by 10. Any idea on what might cause this?
You have "value_default": false, on a numeric value in 3 places (seems small bug in the app when changing type from coil) float16 is not the best dpt for higher values, better use float32.

Where do you set those in the Modbus profiler app?
I tried to set the Default value to 0, but it is not being saved.

So I will need to define the Default value on another application and then upload to LM?
Regarding the dtp, you are referring to the dtp of the KNX object?
