>>21361285 Ok, this has helped a lot. After much testing I've ruled out dp 5,6,7 and 104 using TextFields. All is accounted for apart from 107 which is valid but still unknown. I set it to 1 but it sets itself back to 0. Also I set the alarm off and repeated that test - no different. So yes it could possibly be a calibration setting as mentioned before. Here's a revised autoexec, based on the JSON:
I've also found a workaround for the save crashes (autoexec only) by keeping web tabs open.
One for the display interface where I can click Restart
One from the Web Application - Filesystem tab
One from the Web Application - Logs tab
This way, when the save corrupts after a restart, I can tab over and save again, tab back and restart. This works 100%. It's just unfortunate that most times it means 2x saves, occasionally 3, sometimes 4 just to get it to load right. Not good for flash wear but it is what it is.
After much experimentation, looking through the commands, and ChatGPT getting it wrong, I've given up on decimalisation in the autoexec. Looks like it can only de done in HTML, which if it wasn't guaranteed to crash the device I'd love to try and work on again. So instead of trying to copy the nice display on the web inferface, I'll see if I can get the values from MQTT into Home Assistant and then modify them.
Thanks everyone for your help with this. With just dp107 left we're almost there.
