Via my support kinnan.dk I have been told they introduced rate limitations Feb 5 2024 our of the blue. I have complained as I think that is unacceptable without any warning and time to get things adjusted.

Same here, no more home heating. Is there any change this plugin can be updated?

[ABnFbo]

Had no problem until I two days ago upgraded to 2024.2.1, from 2024.1.6. Then I lost all melcloud climate.* entities.
Restored my partial backup to 2024.1.6 same day, entities and functionality came back. Still working today.
So obviously not only a melcloud issue. There must be something changed in 2024.2.1 that creates problems with the melcloud integration.

I contacted Mitsubishi support and they answered that they have set a rule for how many questions can go thru from a third party software (homeasisstant for example), asked now how the rule is set requests/time..
Answer i got in Swedish:
Mitsubishi Electric har infört en trafikbegränsning för att få ner en allt ökande extern trafik till Melcoud systemet.
Denna trafik kommer från externa tredje parts appar som automatiskt loggar in och frågar om temperaturer och driftläge, ofta flera gånger per minut.
Det som händer är, att om någon användare försöker logga in onormalt många gånger per timme, kommer systemet att blockera inloggning i ett par timmar.
Sedan går det att logga in igen men om samma inloggningsmönster händer igen kommer kontot att blockeras igen.
För att återställa tillgängligheten till det normala måste antalet frågor/inloggningar som görs minskas.
Då kommer användaren tillåtas ansluta igen när den aktuella blockeringstiden går ut.

I use 2024.1.6 and got same problem.
I'm afraid to think about DIY controller for Mitsu :(

Update on my end, i missed the previous fix for HA. See: #109728
My MELCOUD was banned also,
Disabled the plugin, updated to the 2024.2.1 release.
And waited 2 hours for the ban to lift.
Its been working fine ever since, i did not lose any settings /devices on the upgrade.

> Its been working fine ever since
It works fine till the next restart HA

Unable to reproduce, after HA restart its still fine. Did you upgrade to 2024.2.1? You say you are still on 2024.1.6
And yes that version has the issue. (because MELCOUD changed their hammer limits)

I was still on 2024.1.6 and didn't have this issue. Updated directly to 2024.2.1 an hour ago and my climate control stopped working

Update: Reverted back to OS 11.4 and Core 2024.1.6. Climate control is working again

It can stop work after couple of restarts HA.
I make new entity and restarted HA 2024.1.6 2 times. MELCloud stoped work.

Workaround:
Use a 2'nd and a 3'rd or 4'th account installed via Melcloud-App.
So you're able to connect over the App to you Machine.

Hello, I am running into the same issue, but also the app is not connecting properly.
In the main window I see the unit, it says it is on and gives the current temp, but when I click on it, it says that it cannot connect to the MELCloud.
It seems that the user is blocked completely. I do not have other accounts.

EDIT: just got this message back from them: "We have detected excessive traffic from your account, your access to the service has been limited for a few hours."
