-==== Controlling loop ====
-There is temperature ramp prepared which controls the heating power of all four heaters between 0 and 100% depending on the Temperatur read on C1.
+===== New slowcontrol with Node Red =====
-Run inside a screen session:
+==== Installation ====
-  /home/pi/python/actor/actor.py
+Install docker on the pi via: <code bash>
+wget -O install_docker.sh get.docker.com
+sudo sh install_docker.sh
+sudo usermod -aG docker pi
+</code>
+and logout and login again.
-Code can be found here: https://gitlab.rlp.net/bes3-mainz/mogon-testbench/snippets/497
+Next, create an volume to permanently store data and run <code bash>
-==== Bare metal controlling of the heaters ====
+docker volume create --name node_red_user_data
+docker run -d -p 1880:1880 --restart unless-stopped -v node_red_user_data:/data  --name nodered nodered/node-red
+</code>
-HINT: Better use the web interface to get the status and set the heaters power: http://localhost:10001/status.php#page1
+Open the webpage: http://localhost:1880
+and install via the menu further packages like ''node-red-dashboard'' to build a GUI.
-Control the heaters be writing them a value in the range ''0.00'' and ''1.00'':
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer<Dimmer ID 1..4>/set' -m <brightness 0..1.0>
-Example:
+Source code:
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer4/set' -m 0.75

-<code bash>
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer1/set' -m 1;

+==== SNMP Hints ====
+To set and get info from the Brennstuhl multiplug (IP address 10.106.11.21) run the following commands:
+Copy the MIB file into ~/.snmp/mibs/nbs.mib . In case an error is stated, change ''ws_brs'' to ''wsbrs'' in the mib file.
+The use the MIB file, add
 <code bash>
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer1/set' -m 0;
+  -m ALL
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer2/set' -m 0;
+</code>
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer3/set' -m 0;
+to all your commands. BUT note: the mib file seems to be a bit buggy. To get the ISO numbers, eg add ''-m none''.
-  mosquitto_pub -h mould-control -t 'homie/fsrcontrol/heater/dimmer4/set' -m 0;
-  echo "done"
+Perform a complete walk of all parameters
