+## RECEPTION ISSUES
+
+### My sensor doesn't receive any readings from my sensors anymore or only occationally
+The custom component uses Bluetooth (BLE) to receive messages from your sensor(s). The number of messages per minute that are being send by your sensor depends on the type, but is around 20 messages per minute for LYWSDCGQ, LYWSD02 and CGG1 sensors, around 2 per minute for HHCCPOT002 and around 1 per minute for HHCCJCY01T.
+
+The number of messages that are received by Home Assistant can be less or even zero. Parameters that affect the reception of messages are:
+- The distance between the sensor and the Bluetooth device on your Home Assistant device.
+
+Try to keep the distance as limited as possible
+
+- Interference with other electrical devices.
+
+Especially SSD devices are known to affect the Bluetooth reception, try to place your SSD drive as far as possible from your Bluetooth tranceiver.
+
+- The quality of your Bluetooth transceiver.
+
+The range of the built-in Bluetooth tranceiver of a Raspberry Pi is known to be limited. Try using an external Bluetooth transceiver to increase the range, e.g. with an external antenna.
