I have a ds18b20 temp sensor running on v1 and that works fine.I tried adding the eventor to v1 in order to trigger a temperature notification if the value goes too high. above 20 C. i have installed the notification widget aswell. but nothing happens when the temp goes over 20C. i will upload the sketch mayby the problem is in there somewhere. any help will be greatly appreciated.
