Hi Vinicius. I think you also sent me an email, but I'm replying here as well just so everyone else has an update.
I also had a problem with my own devices not triggering the past day or two. Looking in the logs there was an issue on the eWeLink/Sonoff side, and the problem seemed to run from April 28th at 10pm UTC until April 29th at 7.30pm UTC. It does seem to be working now and I can confirm my own devices are working.
Let me know if you're still having issues and I'll investigate further.
