I have spent the last few days trying to get my new d1 mini / esp8266 devices to work with no luck.
I am looking for a beginner step by step guide for the initial configuration of openhab + mqtt as well as the configuration guide of a basic esp8266 / d1 mini with relay gpio controls.
I just want to start simple and control some relays using the D1 mini GPIO’s and a centralized openhab server. Nothing more at this time.
I have a raspberry pi setup and running currently with a 8 channel rely board connected and using 6 of the relays to control my garage. I want to convert this to a esp8266/d1 mini controlling the relays and move the Pi into a central location so I can control the garage via the esp8266 and have the Pi in a central location for future OH projects as a central server.
I have been able to get the mqtt server working locally on the Pi but that is about it (It says online in paperUI). I cannot find straight forward documentation on adding items that control the esp8266 from the paperUI or auto detects it, as well I have not been able to find any documents that explain how to program the esp8266 properly to communicate with the mqtt server on the pi / openhab.
There is so much confusing and contradicting information out there on this topic. Openhab is a great product, sadly the documentation is so wildly all over the place it is very difficult to follow. I guess is such the case with any opensource product. Eventually I will have an “AH-HA” moment, until then I am wishing I had hair to pull out.
