I made the hardware as described.
I tried with Wemos D1 mini (esp8622) and with NodeMCU ESP-32S boards.
I tried to power the receiver and the transmitter with the board (it was only 4.6 V) and with external supply (about 7.8V).
I use OpenMQTTGateway v0.8.
The wifi and the mqtt work perfect.
But when I press any remote (I tried 3 different) it doesnát capture the signal.
I tried to change pins.
I didn’t measure circuit break.
Help me, please.
