   - edit ''user_config.h'' and enter your wifi name and password. all other settings can be changed later once the device is booted, but you can of course set them here if you want. this will make it much faster if you flash alot of these devices and want the same settings on all of them.    - edit ''user_config.h'' and enter your wifi name and password. all other settings can be changed later once the device is booted, but you can of course set them here if you want. this will make it much faster if you flash alot of these devices and want the same settings on all of them.

 +==== a word about retention ====
 +it seems node-red sets the retention flag of mqtt by default. I learned this when i used it together with the mqtt-dss-connector: i created a rule that turned the light in the bathroom on. if i turned it off later (not via node-red) and then restarted the mqtt-dss-bridge the light in my bathroom went on again "for no reason" .. this was because that on command was published with the retention flag set to on (or actually not set to anything in node-red). so i set it to "false" and the problem was resolved.
