Awesome Coffee Server - ESP8266 based IoT webserver

[frozenfrogz]

Sorry guys, I screwed up. Don’t ask me why, but after opening a thread on this in the "Projects, Design..." board I remembered the OSHW section and thought it would be better suited here. However, I thought the original thread was removed (but that somehow failed and I did not notice) and then I intentionally created the same thread here. Now there are both threads present :/
I contacted a mod to sort it out, since I myself can not do anything about it right now.
Please do not respond to this thread, but head over to the "projects" board instead.

Thank you!

for your question, i have used many relaies, all without a optocoupler. i believe it is safe enough especially when you make it in a PCBA.

besides, how you will program the ESP module. an nodemcu or nodemcu mini would be help...
