Magichome devices work PERFECT with homeassistant (reflash this code with ESPHOME)

Luuk_Neele · January 23, 2020, 8:46am

Sorry i misread the post, theres indeed a typo in my original post.
i was initially confused because on some other esp devices the pins are flipped on the board itself
but that is not the case here, corrected it.

Thanks for the walkthrough! I just recently moved my Tuya devices to ESPHome, which fixed a bunch of my connectivity issues. Quite a while ago I bought a few MagicHome controllers but Home Assistant only really liked controlling one, and the other two were flaky even with the remote. This method seems to fixing all that though, and I don’t have to trash my 12v strips!

I figured out the IR remote details here in a new thread. Works great!

dave-castle · April 11, 2020, 10:45am

thrown away the remote, just working with Siri
Anyways thx for the hint!

Thanks, the important principle here is that if HA goes down, my lighting should still be functional. Thanks for figuring it out for us!

Has anybody seen a slightly different revision of board for these Magic Home devices?

I’ve got one controller like the one at the top of this thread, however I’ve purchased three more for under cupboard lighting in the kitchen and they board is slightly different.

Close up of the chip, which is obviously labelled differently as in my first controller this was an ESP8266:

Rear, pads appear to be in very similar places:

Front, notice “-E” at the board spec at the top, versus the standard “-A”.

Tried flashing one of them with ESPHome but no luck, was going to try a second one to rule out poor soldering etc but that’s when I noticed the differences so held off for now.
In the meantime I’m using the “flux_led” integration built into Home Assistant, but I’m not a fan of the delay in controlling.

Swap rx and tx pins and then try again

chris_avfc · May 11, 2020, 10:44am

Worth a shot, will try this evening and report back.

chris_avfc · May 14, 2020, 11:25am

No luck unfortunately, still won’t flash.

Luuk_Neele · May 14, 2020, 6:09pm

What error does flashing the esp throw?

jonaslorander · May 14, 2020, 7:06pm

That is no ESP8266! I have never seen the logo on that IC before, and number looks weird, and after a closer look the antenna signal isn’t even on the same pin as on an ESP8266.

See this as reference: https://templates.blakadder.com/unsupported/magichome_ZJ-WFMN-E.html

That explains it!
I did wonder if it was a different chip when I saw the different markings.

I purchased them from Amazon via this link:
WiFi LED Strip Controller Alexa RGB Tomshine https://smile.amazon.co.uk/dp/B07P2HS5BT/ref=cm_sw_r_em_apa_i_ndAVEbMQ7SYRM

I should be able to return them, but will need to find some that are the correct controllers then.

Thanks for the help.

So went ahead and purchased these ones from Amazon:

Turns out they have same chip as my original purchase in…

So I’ll be returning them as well, at least it’s from Amazon so easy to return.

Not sure where to go now as I can’t see a way of confirming what version I’ll be purchasing.
Normally I’d order from Aliexpress, but returns are going to be near impossible.

Does anybody have any recommendations of where to purchase?

My next attempt looks to be these ones as in the reviews somebody has successfully flashed with ESPHome

I believe this is a new version using an ESP Chip. Also uses RF instead of IR for the remote.

It will be delivered tomorrow, so I will update you all.

I too bought one of those £8.69 ones. But it was the SmartChip Semiconductor Co S9070B.
I have also noticed WiFi devices shipping with Mediatek and RealTek chips. Again neither are compatible.

Even Sonoff have started to use other random chips.

chris_avfc · May 17, 2020, 5:04pm

Be very interested to hear what chip is in them once you’ve received

wills106 · May 18, 2020, 4:00pm

I have not flashed it yet, but the above linked Magichome does have an ESP chip and RF.

laca75tn · May 18, 2020, 6:37pm

Has anyone had the following error when flashing it? It connects and writes code to it but at the end I get the following message.

MD5 of 0xFF is 36ed8c0cd10f63f644ac82d112d814ef

A fatal error occurred: MD5 of file does not match data in flash!

ESPHome config for the MagicHome RGBW-RF ZJ-WFMN-B v1.1 controller.
I have mapped some of the RF Remote buttons. I’ll do the rest later and update.
I have done it so the RF control is internal and not relying on HA, so it still works away from WiFi ect.

In case anyone is wondering this seller on AliExpress sells the ESP8285 (the right one) version of these in all the variants (RGB, RGBW, single color, etc). I bought from another seller after not having bought any of these for a while and also received the new “E” variant which is junk for me at this moment in time with the no name chip. https://a.aliexpress.com/_d7HejCt

ptrfrll · June 6, 2020, 1:46am

Did you happen to find a good place to purchase? I’ve tried two different controllers from Amazon and both came with the same chip as yours (ZJ-WFMN-E)
