@DirkB19 Think you will get another advantage by changing as well - must be a lot easier to monitor the MQTT messages when topic clearly shows the difference.

yep. but sometimes, usb powered things are useful, in case of esp8266 which is not a lowpower thing ;)

@hek That was very visible, please excuse my ignorance. Even though I have looked at this page I managed to leave the change unnoticed.

Now the RPi based on a new install of Raspbian Jessie, OpenHab 1.8.0 and Mosquitto is up and running and the ESP8266 MQTT client does connect without any problems. I have not changed anything in the code but Mosquitto is now based on the RPi repository for Jessie and not the mosquito_wheezy one. That seems to have fixed it so those versions are likely different but I have not put any time into checking this.

@vlad I am having the same issue. Where did you change keepalive timeout to a long time? Essentially, what file did you edit, what parameter and to how long?

@Yveaux I already did! https://github.com/mysensors/Arduino/pull/396
