You can try adding cleanuperr to your *.arr stack. It will listen to your queues and if something gets stuck, like .arj files, it’ll remove them, blocklist them, and maybe re-search? I’m not sure.
You can also change your settings in sonarr to not do any rss sync searches with your public indexers. This stops sonarr from seaching those indexers automatically for the next release. I’ve notices most of that garbage pops up before the official release, then gets drowned out by the real stuff after the release. If you leave the auto/interactive search enabled, you can just click the auto search button for the episode the day after it comes out. You likely won’t pick up any garbage this way.
I wrote a script that spam reports these, and I run it when I’m feeling frustrated with a something, but nothing I’ve spam reported with the script has gotten taken down yet. So, that sucks too.
My guess is your heat pump doesn’t have a good dehumidify mode. The thermostat does, but it’s just turning on the A/C. A good dehumidify mode is a very slight A/C and moves a lot of air. So, if your compressor doesn’t handle enough steps down, you’re spending a lot of electricity for not much effect. A dehumidifier with a continuous drain might be a better solution for you.
