Hi everyone!
I was happy to use BLYNK last 5 years and it completely fine. As regards this year we forced to use new version. I adapted my code and successfully run device, but have following issue: as I’m in Ukraine and because of russian invasion we have no any more reliable internet and electricity, my project suppose to be able work with different WIFI accesspoints. Blynk 1.0 worked just fine in such conditions using esp8266wifimulti.h library and switching automatically, but BLYNK 2.0 don’t. Device starting, running, connecting to BLYNK in run on main wifi access points, but on another not connecting to BLYNK server after short time reboot. My code is below. Please help - I’m amateur and coding it’s just hobby.
