Today I found out that the Marmitek SM10, used to monitor doorbell activity stopped working. Looking at my trace-files it stopped around August 18th. :-(   This is pretty annoying as I don’t get camera images when the doorbell rings etc.

After a fast and easy process to return the SM10 to Elekhomica it was send back to me: “SM10 is working fine!”
Ouch. Turned out they were right.

The solution: reset the CTX35. Thanks for the support Elekhomica.nl!
