Is there such an animal as a standalone IR Blaster that can be programmed? What I mean is an IR Blaster that can be programmed to emit certain IR signals at a certain time without needing Alexa or an active wifi connection or a smart phone actively connected or to require a running computer to control it, etc. Programming it with a smart phone app would be fine, just not having to have an active smart phone connected to send the signal to start the device blasting. My non-DVR satellite receiver doesn't have program timers so I want to program it to switch to certain programs at certain times. I see all sorts of IR Blaster devices listed on Amazon but they mostly seem to need an active smart phone connection to perform the actual timer function or they want to tie into some voice command system.
