Athom AR01 IR Controller

Overview

This is an IR receiver and transmitter that is shipped with Tasmota installed by the manufacturer. Manufacturer product page: Athom AR-01 Tasmota IR Controller

Flashing

This device can be flashed by making a serial connection using the USB-C port. I did not test this, but there is what looks to be pads for a serial connection. I would also guess that this could be flashed from the default Tasmota web interface.

Using the Device

ESPHome documentation on receiving and sending codes. The IR codes received may be parsed by several of the codecs. Just pick one of them to use. While testing, it may be helpful to change dump: all to just the protocol your IR remote uses, to make reading the codes easier. In my ESPHome configuration, I ended up with a fair amount of template buttons where each one sends out an IR code using the appropriate remote_transmitter.transmit_xxxx action.
