On this site, I’m blogging about all kinds of exciting and/or tricky topics. Mostly just to write them down for myself. See a few of my latest blog articles below:
- How to fix disconnected Sonoff Zigbee sensors in Home Assistant?This article explains how to fix and reconnect Sonoff Zigbee sensors in Home Assistant, after they have mystically disconnected themselves. The neatness of this solution is that while the eWelink app will assign your sensors a new device id any time you have to re-register them, this approach lets you use the same entity id you had for them before you had to reconfigure them. They don’t unfortunately retain their…Continue reading How to fix disconnected Sonoff Zigbee sensors in Home Assistant?
- How to fix all UWP/WinUI apps being laggy in Windows 10/11?This article explains one way to fix horribly laggy desktop user experience in Windows 10 (and probably 11) when your laptop is beefy enough it should not lag, and even has a dedicated NVIDIA Graphics card. At least applying this fix is going to be quite straightforward – but let me explains first what the issue I experienced actually was like.

- How to export the SSL/TLS certificate from a website using PowerShell?Every now and then, you run into a situation where you might need a SSL/TLS certificate. You could always generate a self-signed one – but that won’t be trusted by anyone, so that’s no bueno. You could also order one online, even for free – but that’s kind of cumbersome, and might come with some weird verification steps. Sounds quite bothersome. Most of the time, it’s the easiest to just…Continue reading How to export the SSL/TLS certificate from a website using PowerShell?
What’s koskila.net about?
The tagline for my blogging efforts has been Solutions are worthless unless shared for quite a while already. That’s to say, since I’ve gotten a lot of help from the community whenever I’ve had issues getting something to work, I like to give something back. This blog is my way of doing that.
Blogging has been a great, lightweight way to sort my thoughts and document weird fixes and findings along the way. And boy, has there been a lot of them! Microsoft’s stack always keeps surprising me – mostly in a positive way, but there’s an occasional bump on the way too.
These are some of the topics I often write about: Azure Active Directory errors, Azure PowerShell errors, terrifying examples about how to open a modal dialog in SharePoint using JavaScript, all kinds of weird new Microsoft Azure -related tidbits of information, a bunch of Visual Studio -related (and other) tips and tricks, and of course the blog’s namesake – SharePoint Problems.
A lot of people seem to struggle with the same issues, as the blog nowadays has around 70 000 visitors monthly. May you find my thoughtful workarounds as useful as I have!
In addition to more technical posts, sometimes I might post about my sessions at different community events, or experiences as an expat living in a foreign country (in 2017, that country was the USA, in 2018 & 2019 Canada). Right before the pandemic, I moved back to Finland to live in the middle of a forest. Quite literally, as I need to somewhat regularly scare moose away or they’ll eat our apples. Our pests are large.
Speaking Gigs
Back in the olden days, when the world was not on fire, I used to travel to different events. Now it’s all digital, which is… Not quite the same.
You can also see a list of all my sessions and session materials.

No upcoming engagements. I’ve cut down traveling due to the pandemic.
