Woke up and it was still 20.5C in the house. And next couple days will be up to 34. So it isn't cooling down enough during night. So I went out and bought a 12000BTU Danby window AC unit. Wanted a Midea one as they are listed as the most efficient on the Energy Star website. But it was the only window unit Costco had. $369+tax.
Get home set it up. It had wifi so I see if I can get it working with Home Assistant. And I find out its actually made by Midea. And sure enough it works on the Midea app that my dehumidier uses. A similar Midea unit sells for about $550 so saved a pretty decent amount for a similar unit.
