Hi all,
I had a similar issue so I thought I would post here in case it helps anyone else.
I have built a 3 phase power monitor to measure my home power usage before installing solar panels. It uses a Wemos D1 mini and connected to a Blynk app. It’s been working flawlessly for months.
A nearby museum has solar panels but they have a huge power bill as well so I thought I could help and monitor their usage. Unfortunately they don’t have WiFi so I thought I could use my old 4Gee WiFi hotspot.
I could connect to the hotspot no trouble but it would not connect to the Blynk server.
After much investigation I changed the hotspot encryption from WAP2 to WAP and it all works a treat.
I now have a fully mobile gadget which I’m sure will find many uses!
Happy Blynking!
