+# stiebel eltron
+
+This module collects metrics from the configured heat pump and hot water installation from Stiebel Eltron ISG web.
+See `netdata/conf.d/node.d/stiebeleltron.conf.md` for more details.
+
+**Requirements**
+ * Configuration file `stiebeleltron.conf` in the node.d netdata config dir (default: `/etc/netdata/node.d/stiebeleltron.conf`)
+ * Stiebel Eltron ISG web with network access (http), without password login
+
+The charts are configurable, however, the provided default configuration collects the following:
+
+1. **General**
+ * Outside temperature in C
+ * Condenser temperature in C
+ * Heating circuit pressure in bar
+ * Flow rate in l/min
+ * Output of water and heat pumps in %
+
+2. **Heating**
+ * Heat circuit 1 temperature in C (set/actual)
+ * Heat circuit 2 temperature in C (set/actual)
+ * Flow temperature in C (set/actual)
+ * Buffer temperature in C (set/actual)
+ * Pre-flow temperature in C
+
+3. **Hot Water**
+ * Hot water temperature in C (set/actual)
+
+4. **Room Temperature**
+ * Heat circuit 1 room temperature in C (set/actual)
+ * Heat circuit 2 room temperature in C (set/actual)
+
+5. **Eletric Reheating**
+ * Dual Mode Reheating temperature in C (hot water/heating)
+
+6. **Process Data**
+ * Remaining compressor rest time in s
+
+7. **Runtime**
+ * Compressor runtime hours (hot water/heating)
+ * Reheating runtime hours (reheating 1/reheating 2)
+
+8. **Energy**
+ * Compressor today in kWh (hot water/heating)
+ * Compressor Total in kWh (hot water/heating)
+ 
+ 
+### configuration
+
+The default configuration is provided in [netdata/conf.d/node.d/stiebeleltron.conf.md](https://github.com/firehol/netdata/blob/master/conf.d/node.d/stiebeleltron.conf.md). Just change the `update_every` (if necessary) and hostnames. **You may have to adapt the configuration to suit your needs and setup** (which might be different).
+
+If no configuration is given, the module will be disabled. Each `update_every` is optional, the default is `10`.
