ESP8266 Community Forum

- Tue Jan 26, 2016 1:47 pm #39758 Sorry for my English, I'm Italian. In addition I'm new in the forum and I'm not sure this is the right section to address my question.
I'm using the ESP8266 12e dev kit. I'm experimenting an SSR (Solid state relays) connected to the dev kit. Everything seems working but if I make an hard reset the dev kit doesn't reload the software . If I use a led instead of the relays everything is ok. The connection of the realys is a direct connection (the + pole to the pin of dev and the – pole to the ground of dev). I choose the SSR relays because it doesnt need any pilot circuit. Any suggestion to solve the problem?
