Does anybody knows how compatible is this unit Midea Solstice 26(09)N8 with HA locally? I need 5 units and I’m considering options
There are 2 huge Midea threads here in the forum which might help you if you look them up.
They explain that it should be possible to have local control of your AC using a cheap ESP board instead of their WiFi adapter. Not sure whether your specific model is supported, but as long as the port is available on the main board, it should be possible.
Check this.
It is working with my midea ac but ac should have usb connector for wifi dongle.
5 units on WiFi? Not sure if that may be wise.
Get them installed with RS485/ ModBus connectivity. Your installer should be able to configure each unit to an unique ModBus address, and then they can all talk to the same/single RS485 controller for maximum efficiency and control reliability.
Hint: Don’t forget only one terminating resistor on each end of the RS485 chain, not one on each a/c unit, so two only to be activated.
Why not?
Good luck with that.
Multiple units, each with their own WiFi is going to cause a bit of unreliability if closely mounted together.
If you have a choice between WiFi and RS485 at design time, go the latter for reliability. You won’t regret hard wiring in the long run, especially as your wireless device count grows across your premises - it will.
I don’t know how op will mount them but it is unlikely that they will be mounted close together. Probably per room.
If this esphome dongle works with its units it should be fine. I have mine for more then a year and it is reliable, doesn’t disconnect and everything is working fine. My ac is not even labeled as midea ac as it is sold by different brand name but under it, it is midea ac.
As he probably have or will have ha, he can control units based on sensor temperature/humidity or combine multiple sensors in one threshold.
Combining a lot of wireless devices shouldn’t be a problem if you know how to stack them properly and build your network infrastructure.
You’re right, there will be one per room
That’s what I want to know. I’ve checked on the forum and I can’t find this unit listed. Is there any way to make sure it works?
Thanks @ShadowFist , I can’t find this model. How can I know if I can use this unit with the ESP32 dongle?
That’s the idea my friend 
Well Thanks for all your responses, But the thing is to know if this certain model works with that ESP32 dongle
Well all of I can think of is to buy dongle plug it in and see. That is how I done it. I had a problem with pushing dongle in usb port as it is a bit hard to do it because port is maybe one millimeter off but I was able to do it.
The thing is I don’t have the machine yet, and I want to buy a machine i know it works with HA
Yeah I know. But there are some integrations that can work with midea ac using their usb dongle that works over cloud.
There is no guarantee that this esphome dongle will work with your ac unit but if those units have usb port for inserting their property wifi dongle, chances are good that it will work with this esphome usb dongle.

Had a look at the manual & it mentions a USB device for wifi, which means that it should have a USB port.
If you’re going to buy 5, I’m sure the supplier will be happy to confirm whether it has a USB port for you before purchase.
Yeahhh good point. I’m checking and I see with ESP32 integration you don’t have all parameters. I would like to control moder (dry, heat, cool), read humidity, fan speed, read temperature to use on automations, etc
Is there any integratios that have access to all these parameters?
It operates all the functions your ac have. At least my does.
