core: Home Connect integration - 2 out of 3 devices not updating at all.

The problem

I had Home Connect integration in use for like 8 days or so, now “it stopped working” 3 days ago, flooding in the Logs something like 429 - Too many requests exceeded 1000 requests per day, waiting for 5353535 seconds or something, which I don’t have anywhere anymore and not getting this error anymore. Once the 24h time period was over, my integration still didn’t work, so I decided to reinstall it:

• deleted the integration
• removed the settings from config/configuration.yaml
• removed the Home Connect developer application I created
• reloaded the configs and restarted Raspberry Pi, just to be sure
• created a new Home Connect developer application, with new Client ID and Client Secret
• added the secrets in config/configuration.yaml
• reloaded the configs and restarted the Rasp to be sure
• added the Home Connect integration

Now my Home Assistant sees my Dishwasher and all of its entities gets updated, I can control it just the way it used to work before. But for my Washing Machine and Dryer, the entities are not being updated. Only entity that gets updated every now and then is the Door open/closed, but the power seems to be updated really randomly in HA (I haven’t found when or why they do update, but it’s really seldom) and any other entity never gets updated. I cannot control these two devices at all. Trying to power them on or off, doesn’t work. What’s funny is that I can control them in Home Connect mobile application just fine, I can see the statuses perfectly, etc.

I’m also getting bunch of errors, such as:

I’m running out of ideas what to do. I think it’s quite “random” that Dishwasher works perfectly, but Washing Machine and Dryer doesn’t work pretty much at all.

As seen in the images below, both devices are powered on, but Home Assistant shows “unavailable”.
