+## node.setonerror()
+
+Use this to override the default "always restart" action if wanted; for example to write an error to a logfile or to a network syslog before restarting.
+
+!!! attention
+
+    It is strongly advised to ensure that the callback ends with a restart. Something has gone quite wrong and it is probably not safe to just wait for the next event (e.g., timer tick) and hope everything works out.
+
+#### Syntax
+`node.setonerror(function)`
+
+#### Parameters
+`function` a callback function to be executed when an error occurs, gets the error string as an argument, remember to **trigger a restart** at the end of the callback
+
+#### Returns
+`nil`
+
+#### Example
+```lua
+node.setonerror(function(s)
+    print("Error: "..s)
+    node.restart()
+  end)
+```
+
+
 ## node.setpartitiontable()
 
 Sets the current LFS and / or SPIFFS partition information.
