Ive got a few Pi’s running with Cayenne for the last few weeks and initially I was getting notifications o.k. when a Pi went offline or a trigger was activated both my e-mail and by SMS however I am now not getting anything as one of my Pi’s is acting up over the weekend and losing power. This should have triggered an offline warning which according to my Cayenne dashboard it did run. Also another one exceeded a threshold where I set a trigger previously which worked. Again nothing was sent to my e-mail address nor SMS. For triggers via SMS should the format for the UK be ‘44123456789’? so no 0 or + before the 44?
you might have hit trigger limit Sending MQTT messages within notification limit
