+# Charging Dock
+
+When charging shows the time, scans Bluetooth for known devices (eg temperature) and shows them on the screen.
+
+Rotates by 90 degrees if it detects it is sideways, allowing for use
+in a Charging Dock.
+
+When devices are out of range (eg low water level in a plant) they are
+highlighted red.
+
+Currently supported devices:
+
+* Mi Flora/other Xiaomi
+* Bluetooth 0x1809 (eg. [Espruino Apps](https://espruino.github.io/EspruinoApps/#bletemp))
+* Espruino Manufacturer Data (0x0590)
+
+In the future it'd be nice to support more types of device in the future!
+
+## Espruino Devices
+
+To use your own Espruino device, use code like the following:
+
+```
+var data = {a:1,t:E.getTemperature()};
+NRF.setAdvertising({},{
+  showName:false,
+  manufacturer:0x0590,
+  manufacturerData:JSON.stringify(data)
+});
+```
+
+Currently:
+
+* `t` is the temperature (if defined)
+* `t` is the alert status (1 or 0)
