1. The remote control is the learning code 433.92MHz (cannot copy). It mainly learns the 1527/2262 learning chip. It cannot learn if it is not a learning chip, nor can it learn a learning chip which is not 433.92MHz.
2. Learning method: long press the button of the receiving device for 5 seconds, then long press any button on the remote control for 3 seconds.
3. After learning, don’t use the remote control too frequently. It’s better to press the second time after 1s after the first press.
4. The number of learning remote controls is determined by the receiving device. For example, SONOFF RF R2 can learn 9 remote controls. When learning the tenth one, the first remote control will lose its remote control effect. If the receiving device can only learn one remote control, then when learning the second one, the first one will lose the remote control effect. Other SONOFF products with RF function also operate in the same way.
5. There should not be too many metal partitions between the remote control and the receiving device, otherwise it will affect the signal reception.
