how to make an ESP easy MQTT Oled Info display???

[jascdk]

Hi. I have thought on making a info display that shows / displays, the current status of my home - by checking what appliances is on and which are off.

I have multiple sonoff switches which have been flashed with tasmota and they are controlled over Apples HomeKit.

I currently have a Nodemcu and a oled I2C 128X64 screen connected to the ESP8266.

I have tried to flash Esp easy on the board and it succeeded. But as I can see, then I can only get mqtt messages like temperatures and so on.

I have setup a raspberry pi with mosquito on as MQTT server.

Any guides and help would be appreciated:)

All the best

Tasmota is formatting the payload as JSON, MQTT Import only handle single value payload. You'd have to get the in between controller to feed the messages.

And how do I do that? I am a total newbie on this one:D

I'm no Apple Homekit user so sorry, cannot help you there.

I you have already a Raspberry Pi, you can install Node-RED. Then you can make "a flow" that reads MQTT messages, manipulates them, and sends them out with another topic.

Can I install this Node Red along HAP-NODEJS on my pi, without this is messing things up?

I mean - does Node Red have to take advantage of the whole SD card on the pi, so the PI afterwards reacts like only a Node Red machine?
