Hello…
Just wanted to share that my mr cool 27k dualhead us mini split works like a champ with these home made dongles and esphome on them…to all out there who are afraid that regular usb does not fit into the strange plug…IT FITS…just needs some effort…worked totally fine with both of my units.
Used this how to and it is just straight forward and works
Does it mean just a small hammer, and all fits?
Nope regular pushing works…
Can anybody tell/show the wiring scheme for this? I have already burned one, so I’m trying not to repeat the magic
I put reply on the post but it no made the quote, sorry.
The help I need is about conecting the SWLF-01 to the programmer to flash it, I flashed it via OTA but can’t find it anywhere, the config is correct since it’s the same as other one I used on another dongle.
Hmm…can’t really help here, should be a mix of the wiring I showed in the 1st topic and the picture provided by manufacturer
Thanks anyway @aceindy , I sent a pm to @iamvlanone, lets see if he can help based on what he did on his reply above ( this )
Hi, i have a problem setting follow me feature in my Midea AC with dongle.
I have soldered dongle with board with 1 wire. Button, swing seems working right. I can’t handle the follow me feature. It seems i’m missing something.

any ideas? What Am i missing?
Hi @Stormhand, did you managed to control the unit with Modbus protocol? I have a Clivet heatpump Air and i would like to try to control it with the same method. I own this unit: Clivet Sphera Evo 2.0 and as you, i found the complete table of parameters in the instruction manual. I haven’t bought anything yet. I hope that you can give me some suggestions
Hi @cash18 i just received the module but havent tested it yet. I have to solve the problem how to pull a cable from an external building where the pump controller is mounted. Otherwise i cant test it.
Hello again @aceindy and everyone else, regarding the SLWF-01 subject ( this ) I asked the seller and they sent me photos and this information:
" You asked: Hello, I bought one piece of these, updated via OTA and I cannot see it anywhere, the configuration is the same that I have used on another dongle (with different name and IP). Can you share or explain how I can connect it via FTDI to flash it?
We answer: Unfortunately, this is a known problem. We ship fully functional devices, sometimes our customers update them via OTA and they stop working. I think this is a problem on the esphome side. I sended you a email and attached a picture because we can’t add pictures here. "
Hope it helps someone else, I havent tried flashing the dongle yet but I guess that will not have any problem
Update from Taras (smartlightme) :
“Don’t forget to hold the FLH button and then press the RES button to put the module into firmware flashing mode”
Update: just followed the instructions and the problem was easily solved.
Hi all,
Is the consensus that we’re SOL if we have Midea systems that predate the wifi dongle USB port? Mine are from circa 2016 so no wifi, and I can barely find anything that acknowledges their existence. My house has these units:
MEHU-24AVD2
MEHU-18AiD2
MEHU-12AiD2
I’m hesitant to use an IR system and I would much prefer to use something with two way communication, but I fear that might be my lot in life with these units.
Thanks!
Hello everyone…
I go crazy…
I try to get my ac started via automation but i always get that the service is unknown error…
My automation code is this:
alias: Test climate
description: Turn on when...
trigger:
- platform: time
at: "13:13:00"
condition: []
action:
- service: bed_room_ac.turn_on
data: {}
- service: climate.set_hvac_mode
data:
hvac_mode: heat
target:
device_id: 29db89185fda53e7e9425b9a7e403882
mode: queued
max: 10
The bed_room_ac is selected from the gui…so it should be known…
Any ideas?
Here the error message:
The automation "Test climate" (`automation.test_climate` ) has an action that calls an unknown service: `bed_room_ac.turn_on` .
Where do these services determined?
And does anyone have a working setup with ac automation that i copy cat for testing?
Thx alot
you forgot to tell ha which device to target for
service bed_room_ac.turn_on 
alias: New Automation
description: test
trigger:
- platform: time
at: "19:57:00"
condition: []
action:
- service: climate.set_temperature
data:

- service: climate.turn_on

target:
device_id: 27f30bb7dc1090ba0aa4217e4c1ec025

Tip: check your automation traces😉
Hello…
Thx for your answer…i finally found why it never wanted to work.
the webui always adds the not needed
action:
--> - service: bed_room_ac.turn_on
--> data: {}
- service: climate.set_hvac_mode
data:
into the code…
it works when i remove the with → marked lines…
Must be a bug in the webui…but was driving me crazy
Have now my frost safe setting working…
Start when my rooms reach 15C…
Now i try to get the AC to turn off as soon the set 18C is reached…is that somehow manageable so that it does NOT interfere with when i do warm up the room by manual turning the AC on?
Thx for any thought…
And besides that…can i actually turn on the “follow me” function via esphome code in the dongle itself so that it is the default? i mean right now it will be the remote control, but later on i am planning to use the Xiaomi temp/humidity sensors to do the job…
thx for any thought
Hello again…
Back at the ac project and need some intel…maybe someone here does know more.
I now have the xiaomi twmp/humidity sensor in wvery room and would like to use those values as base for the room temp shown in the ac card in hass and as the follow me temp.
I saw kuchar’s reply some up, mentioning similar question…
So does anyone know if follow me is actually accessible via the usb dongle or just via remote and as kuchar mentioned…is there any soldering possible to bypass this limitation if possible?
Any help is highly appreciated…
The follow me is only available when the esp module is either equipped with IR transmitter , or wired directly to the IR receiver.
See Sending and receiving IR remote control commands in dudanov’s iot dongle regarding the follow-me options.
Hi Jakob!
Are you still planning on publish your project? I have a similir control unit and I’m trying to communicate using a MAX-485 module but whenever I connect the MAX-485 to the control unit’s HA/HB ports then the unit displays an error and restarts itself (even if I just connect MAX-485 without any other wires than A/B).
Thank you
Which terminals are using? XYE or H1/H2.
