I installed 2 different IR transmitters: Blitzwolf IR controller and Shojzj (!!!) IR/RF controller (model JS-A1-433MHZ) and both work very well. Shojzj even learned the RF signals (great!).
My question is: when I install these devices in IRControl app, they disappear from the Tuya or Smartlife app, and this way I cannot use these devices by voice command (with Echo Dot or Google Home). How to solve this?
No, there isn't an open API for sending commands directliy to the device, otherwise we would use it. We see it generally not as a very good solution to control an infrared transmitter over a cloud. There are several problems, so we think there exists more interessting devices.
