I noticed this the last heat wave we had when I lost connection via Blynk. It has since happened again. Factory reset fixed it last time, however I have not had the time to reset it again. I did reset the WiFi, and reconnected to my APs. I have also verified the Blynk token, however it still isn’t communicating. The garage is very hot, as we’ve seen 100+ degrees the last few days. I can view and control the unit from the web interface via the local network, albeit, very slowly.
If blue light does not blink within 10 seconds (sometimes the logic is reversed, so it stays on, and blinks off every few seconds, that’s normal), it sounds like the software is getting stuck somewhere, which could be because of sensor reading or something. On the other hand, if you can still connect to it (albeit very slowly), that means it’s still running and the blue light should blink even if very infrequently. Something isn’t very consistent here, I feel.
