hey guys, i have got my nodemcu to work with mqtt and openhab2 finally. but there’s one thing i want to ask. is there any solution for using arduino uno with openhab using one of those esp8266-01 modules?? the esp8266 and arduino uno are connected via the TX and RX pins. i tried this is on my own…

Not sure that I am fully following. Do you want the ESP8266 just to serve for wifi access and the arduino actually do some controlling of some devices? The ESP8266 can do almost everything the arduino can do (plus wifi etc). Alternatively you can have some shields for arduino for internet access, t…

i want to controll my arduino uno through openhab using esp8266. my solution was that the esp connects to the mqtt server and receives and sends the payload like any other esp would do but i connected the arduino to its tx and rx pins so that it forwards the payload messages from the mqtt broker to…

Hi Sai_Khurana, I’m also waiting for my arduino ESP8266 Relay :slight_smile: Hope this thread will help you [OH2] Control ESP8266 Relay using MQTT Eventbus

I am sure that is possible somehow, but again I think this is the wrong forum (Arduino forums or esp8266 centers forums may be better) and frankly, not sure anyone tried that. You are more likely to find solutions that are Arduino only or Esp8266 only, combining them that way may make sense only …

I never tried my esp8266-01 as an arduino shield once I discovered I could program it directly, I just used the esp in place of the uno. I had it working with a local mqtt broker and openhab however then I realised the 01 is really lacking in sufficient easily accessible gpio. I now use a (few) wemo…
