Hi @den_box, apologies for the trouble. Can I assume that the device you’re having trouble with these triggers on is connected via MQTT? We’re aware of an issue with MQTT device online/offline triggers aren’t firing at this time.
I’ll update as soon as its fixed – until then, if it is an Pi/Arduino/ESP8266 and these online/offline triggers are important for you, the workaround would be to connect via the respective non-MQTT options in the Cayenne UI (ESP8266 can unofficially be connected ‘as an Arduino’ in Cayenne following the steps in this post). The non-MQTT options should have functioning online/offline triggers.
