-  - download the latest [[https://www.arduino.cc/en/Main/Software|Arduino IDE]] and unpack it.  +  - [[setup arduino IDE for ESP8266]]
-  - create a subdirectory called ''portable'' +
-  - start your arduino IDE and go to ''File->preferences'' and add this to //Additional Boards Manger URLs//:  ''http://arduino.esp8266.com/stable/package_esp8266com_index.json'' +
-  - select OK and go to ''Tools-Boards...-Boards Manager...'' and enter ''ESP'' into the search. now install the ''esp8266'' module and close that window. +
   - download the sourcecode tar.gz or zip package from the [[https://github.com/arendst/Sonoff-Tasmota/releases|Tasmota releases page]]   - download the sourcecode tar.gz or zip package from the [[https://github.com/arendst/Sonoff-Tasmota/releases|Tasmota releases page]]
   - extract the contents of the ''lib'' directory into your arduino ide's ''portable/sketchbook/libraries'' directory and extract the entire ''sonoff'' directory into your arduin IDE's ''portable/sketchbook/'' directory   - extract the contents of the ''lib'' directory into your arduino ide's ''portable/sketchbook/libraries'' directory and extract the entire ''sonoff'' directory into your arduin IDE's ''portable/sketchbook/'' directory
-  - verify your settings under Tools are like these: <code> 
-Board: "Generic ESP8266 Module"  <<<<!!!! 
-Flash Mode: "DOUT"  <<<<!!!! 
-Flash Size: "1M (no SPIFFS)"  <<<<!!!! 
-Debug Port: "Disabled" 
-Debug Level: "None" 
-LwIP Variant: "v2 Prebuilt (MSS=536)" 
-Reset Method: "ck" 
-Crystal Frequency: "26 MHz" 
-Flash Frequency: "40MHz" 
-Upload Using: "Serial" 
-CPU Frequency: "80 MHz" 
-Upload Speed: "115200" 
-Port: Your COM port connected to sonoff 
-</code> 
   - 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.

 this might be different in your setup, but I would like to install the npm modules globally and then run them as non-root users through a systemd script to make sure they are auto-startet as soon as my system boots. this might be different in your setup, but I would like to install the npm modules globally and then run them as non-root users through a systemd script to make sure they are auto-startet as soon as my system boots.

 eventually I'd like to write a script that uses the [[https://github.com/plan44/vdcd|plan44 vdcd]] external device API to integrate a sonoff device into a digitalSTROM setup as an emulated digitalstorm device. this will overcome the lag that is generated by querying the Web-API. we could then also create a dummy light bulb which will just publish its state to MQTT. by assigning it a different value for all of the scenes it is in, we can pass the room-state to MQTT with almost no lag. This will enable other devices like the sonoff to react immediately and not just during the next poll-interval.  eventually I'd like to write a script that uses the [[https://github.com/plan44/vdcd|plan44 vdcd]] external device API to integrate a sonoff device into a digitalSTROM setup as an emulated digitalstorm device. this will overcome the lag that is generated by querying the Web-API. we could then also create a dummy light bulb which will just publish its state to MQTT. by assigning it a different value for all of the scenes it is in, we can pass the room-state to MQTT with almost no lag.
