Hi, Sorry you are having issues... I don't believe I've seen anything like this before but will be able to try it out tonight (currently traveling back from CES) and let you know if I can reproduce it. In the meantime if possible if you can send your config file to info@omniot.com that would help. If needed, you can just dummy out any private values (i.e. your server ip addresses, etc.). Also, I believe you are connecting with the NXP sensor (via the auto-connect), correct? And only enabling the light sensor for notifications? I'll follow up tonight and let you know what I find... thx!
