I bought some IR transceivers and 433mhz receivers & transmitters on Ali a while back. I recently purchased one of these 433mhz remotes as well.
I’m experienced enough with HA and ESPHome by now that I’m very puzzled by my predicament, which I am experiencing with both ESP32 and D1 Mini boards.
When I connect the IR receiver and dump raw data, I get nothing, ever. I have tried, albeit haphazardly because I don’t really know what I’m doing, tweaking the filter, tolerance, idle, etc. and there has been no effect. I have also tried inverted: True & mode: INPUT_PULLUP to no effect. I get no raw data. I have two of these IR modules and I’ve tried them both. I’ve tried the RX and TX pins (just in case) on both. I’m powering the IR modules with 5v and the red LED lights up on both modules, indicating that there is power coming to them. My IR remote works. I just inserted new batteries and turned on/off my TV with it earlier today. I have triple-checked the pinout diagrams via an image search and I’ve assigned the proper GPIO pins. I’ve also moved to other pins and done the same. No raw data.
On to my 433mhz modules. I bought two of these as well, and I’ve tried both modules on ESP32 and D1 mini, with my 433mhz remote from Ali. It has an indicator LED at the top when buttons are pressed, and it lights up with every press. Fresh battery inside. When I dump raw data, I get a huge dump of cascading data in the log. So I then try rc_switch and again (not really understanding what I’m doing) I tweak the various settings for tolerance and such, starting by matching the exact settings that others in this forum have used (I’ve searched this issue in the HA community already) and when that hasn’t worked, I’ve further tweaked the settings. I never get anything with rc_switch. I’ve even tried just dumping raw and pressing the button in fast succession to try to capture a glimpse of consistent data in the dump (viewable when downloaded). This hasn’t been fruitful.
I’m at a loss here. I have two modules of each type, as I stated, so when one didn’t give me any results I’ve tried the second. I’ve checked the seller’s listings and I haven’t seen any mention of the items being faulty. It seems like it should be a simple task. This gentleman seemed to have no such issues. I wonder whether anyone might have any ideas.
