Receiving Infrared Remote Control Data - stodev-com-br/Tasmota GitHub Wiki

An inexpensive IR sensor such as a TSOP1838 can be connected to a device running Tasmota. Configure a free device GPIO as 'IRrecv (51)'. When Tasmota receives an IR message, the data portion of the payload has the same format as the IRsend parameter.

{"IrReceived":{"Protocol":"<value>","Bits":<value>,"Data":<value>}}

This JSON payload data can be used in a rule such as:

ON IrReceived#Data=<value> DO <command> ENDON

If the data is received on an unknown protocol, setoption58 1 See here.
