Paging @stupidbird

Man. back in the day where you got these big ass catalogs and would look at all of the cool crap you had no way to afford. A family member was into all kinds of stuff like this. They had a wrist watch that you could program phone numbers into and use it as a phone book.. Because you know, phones work off tones. You would just select a name and hold the watch near the receiver and it would dial for you. Cool shit when it was back in the 1990's.

From the post: "Hi. My name is Cabel. And I’ve probably got the neatest job in the whole world.

I wear many hats. But here on my personal blog, I get to write about the things I really care about, just for you. And from the fact that you’re reading this blog at all, I think you may be a lot like me."

I still use it, it's controlled by a serial controller running custom scripts on a Pi. It's still just as noisy, but I don't mind it. I appreciate that I can hear when a light is being turned on automatically.

The remote is cool, it's ultrasonic instead of IR.

Its neat but Im just glad to have some of the new stuff with status, power monitoring, etc.. I build some custom modules with ESPHome now too. Really handy.

I tried ESP modules. The raw modules you get from vendors have a massive RF spur at 319.98MHz, which is just close enough to 320MHz that it kills other devices I have.

I've got couple of doodads that use ESP modules, and they don't do that. I wonder if there's something about the firmware that's not custom to a device causing that.

Good question. Ive not really done much to tinker with the frequency side of things. Maybe trying other firmware's would be worth a shot.

Cheap chinese garbage with noisy RF sections. I bet if you check one of these problem causing units with a RF spectrum analyzer, you would discover it is emitting a lot of noisy sideband garbage RF and probably has some whistles at various harmonics. I don't think it's the firmware when the RF section is made so poorly that it would easily be the cause.
