+# `0x18` Speed/RPM
+
+Cluster `0x80` → Broadcast `0xbf`
+
+The cluster will periodically broadcast the current speed, and rpm, while the bus is active.
+
+### Example Frames
+
+    80 05 BF 18 1A 0E 22
+
+## Parameters
+
+Fixed length. 3 data bytes.
+
+| Parameter | Index | Length | Type    | Note                                                      |
+| :-------- | :---- | :----- | :------ | :-------------------------------------------------------- |
+| Speed     | `0`   | `1`    | Integer | multiply by 2 (1A = 26, real speed is 26\*2 = 52 km/h)    |
+| RPM       | `1`   | `1`    | Integer | multiply by 100 (0E = 14, real rpm is 14\*100 = 1400 rpm) |
+
+### Speed
+
+TODO : add information about the Speed sensor
+
+This value is a whole number (i.e. 26) to be multiplied by 2 to get the real speed value.
+
+### RPM
+
+TODO : add information about the RPM sensor
+
+This value is a whole number (i.e. 14) to be multiplied by 100 to get the real rpm value.
+I did not find any way to get a more precise rpm number.
+
