Checksum is incorrect - Githubissues

sa1ntik commented 1 year ago

Hi, Artem!

I’ve faced with some checksum error. The log says:

{"level":"error","input":{"Command":106,"Payload":"FLucRpm5EV2o+VxYVGBZjg==","Mac":"ec0bae0c170a"},"time":"2023-04-24T17:21:24Z","caller":"/go/src/broadlinkac/app/app/service/service.go:332","message":"Checksum is incorrect"}
{"level":"error","error":"ErrorInvalidResultPacket","device":"ec0bae0c170a","time":"2023-04-24T17:21:24Z","caller":"/go/src/broadlinkac/app/app/service/service.go:1130","message":"Failed to get AC States"}

Any guess? Thanks!

Have you encountered this problem in a similar project? If not, then it looks like I'll have to check the checksum verification function.

Not this checksum problem. In Arbuzov addon, I had other problem:

https://github.com/Arbuzov/hass-broadlink-ac-mqtt/issues/9

I get this log when I started addon:

Starting Monitor... Authentication Failed to AC init() should return None, not 'bool' Stopping Starting Monitor... Authentication Failed to AC init() should return None, not 'bool' Stopping

But now, your addon seems to communicate with AC well , but I don’t know why checksum fail.

May be this error is related to the code that the AC Freedom app ask me to introduce just after install? Did you have to introduce a code? What is your code?

I don’t remember the code but then I will send you the code that is printed in my user manual. In Arbuzov addon, some users told me that the solution was remove device from app acfreedom, and add again but only until step of connect to wifi. I didn't tested this solution because I don't want to lose AC Freedom app functionality.

You can use the device here and there. The AC Freedom app only helps you connect your device to Wi-Fi. I used another application to connect it, since AC Freedom didn't want to work for me. Moreover, these air conditioners have serious security problems, since anyone who has access to your Wi-Fi network can essentially control the air conditioner. It is enough to know only the Mac and IP of the air conditioner to connect to it via Wi-Fi

I think that this could be the problem, may be the last versions of ac freedom uses a password to communícate with ac. If you make a beta with detailed log I Will send you this log to analize the problem.

I builded it without the checsum function. You can try. https://github.com/ArtemVladimirov/broadlinkac2mqtt/releases/tag/v1.4.1-beta Or hassio beta branch https://github.com/ArtemVladimirov/broadlinkac2mqtt

If this does not help, then most likely the device uses a different message format that is not supported by this application.

And i leave here one more "input" what I found on HA forums... maybe this make all things more clear

" bad news is that none of the current methods work with the new Aircons. It appears that only one TCP port is active; the previous UDP methods are no longer available. Maybe someone can figure out what the communication is or what this port is used for in order to obtain some statistics."

nmap -p 12416 10.10.1.100

Host is up (0.071s latency).

@marcoahp @ArtemVladimirov JFYI - I have 4 air conditioners at home, all produced by AUX (the two that can't connect are 1-1.5 years younger than my other two that can be connected via Artem integration

above i put info from HA forums about closed ports in "new broadlink based devices" and based on that I checked and this is what i got from my devices (these are the two that can't connect) :

Starting Nmap 7.80 ( https://nmap.org ) at 2023-08-31 15:57 CEST Nmap scan report for x.x.x.x Host is up (0.048s latency).

and second one

I've observed that my mac and one laborek's mac, single01 mac and arunas-g mac starts with "a043". How your mac starts, Artem?

Good news Artem, now your integration works like a charm in my three AC devices!!! Even better than other two Midea AC devices because AUX AC send temperature values with more precission. I had to delete devices from AC Freedom app, and then add again, but only until they connect to wifi, then cancel. The problem is that I've lost AC Freedom connection, and now I can't change some configurations of AUX AC, like Anti Fungus and Health functions. Is possible add theese functions? For example led switch works fine.

ArtemVladimirov commented 11 months ago

It is possible, please, create separate issue for this function. I will think how to add this. The main difficulty is that not all devices support this functionality. I'll have to think about optionally setting this parameter.

Hey, what's the situation with this issue? I updated to the latest 1.5.5, but I'm still getting: {"time":"2024-04-12T12:36:52.230029896Z","level":"ERROR","source":{"function":"github.com/ArtemVladimirov/broadlinkac2mqtt/app/service.(*service).GetDeviceAmbientTemperature","file":"/app/broadlinkac2mqtt/app/service/service.go","line":228},"msg":"Checksum is incorrect","input":{"Command":106,"Payload":"Fs0Rbe/ji/q6hXD8QcD7vg==","Mac":"24dfa7f61a98"}} Are there any plans to fix that issue? Thanks!

Just want to confirm that, if there is a problem with checksum you have to remove the device from ac freedom app, reset wifi and after the wifi is connected once again (in the ac freedom app) just cancel and you will get connection. If it's still not working, just take a look at a hardware approach https://github.com/GrKoR/esphome_aux_ac_component/blob/06388ebb2c2792098e93dd844c3c812440a06288/README-EN.md#esphome-aux-air-conditioner-custom-component-aux_ac
