Really good, thanks! Any chance you started working on the "effects"? (or am I just not understanding something?)

As it happens, I have! Not all of them seem to work correctly, and there's probably a better way to implement them, but I'll put everything up.

Great! Yes, there must be a better way but your working implementation is better than mine non-working ;)
I also see some problem using them as you state - so I will just use SW-effects, works fine for me.

This is great, do you have any information on how to put the Spider Z (Sonoff L1) into programming mode other than mashing the chip pins to ground GPIO0 at PowerOn ?

I was going to try the Swim or Res pads when I get a working image

Unfortunately you have to short the pin on the chip to ground, it’s kind of a pain. One thing I did find is that I needed to keep the pin shorted for the entire flashing sequence.

There’s a bit more info on my blog post about it.

Hey, first of all, great work on this! But, will there be any updates in the future to add receiving support from the remote?

Thanks, I'm glad people are finding it useful! I don't use the remote, so I probably won't be making any updates.

I’ve used this in the past but then decided to see if Tasmota’s integration is any better.
Ended up sticking with Tasmota for a couple months.
Decided to move back today due to the fact that I can setup software effects easier.

Thank you very much for sharing this code, Emory!! :)

I'm having trouble compiling it with

Any ideas?

What version of ESPHome are you running? It's possible something broke in a recent update that I'm not using yet.

1.19.4.

Not a problem for me to switch back to one you've used, compile and flash. Can you tell me what's the version you've used (more or less)

Ok, so, downgrading did not help.

the problem was that sonoff_l1.h file that was copied to led_strip_1/src/sonoff_l1.h by esphome/platformio was empty. Not sure why, but I've filled it with correct contents and it worked.
