iiinova — where your digital self keeps evolving

Last session at #cybersec Netherlands the "inactive" privacy officer Pieter is explaining about the DigiD debacle.

I just programmed my Kincony KC868-M16-V2. A 16-port CT clamp measuring device. I'm hoping this will allow me to measure current on 16 individual devices. #geek #nerd

Stephan van Rooij @svrooij.io · 24/08/2026

I'll be installing this Kincony M16 v2 board to measure realtime power usage of 16 different devices/rooms. And then get rid of all those power measurement devices around the house.

What did you get this time? Well I'm giving a talk on home automation with #dotnet, and I want to show how you can use a cheap wifi chip to mod a dump light to be wifi controllable. #esphome

What do you think is in this small box (screwdriver for reference), it is worth around €600 😯 and has to do with #security

Stephan van Rooij @svrooij.io · 15/04/2026

I'm stoked to tell all off you that I joined the organizing team for @dotnetzuid.nl #community meetup #dotnet www.dotnetzuid.nl

Stephan van Rooij @svrooij.io · 23/01/2026

I had the pleasure to speak a @dotnetzuid.nl and share my latest #security project. An introduction to IdentityProxy. Check out my key take aways svrooij.io/2026/01/23/i...

Tell me how old you are, without telling me your age? Let me start. I have this box in the attic with these things in it. (Which I bring to the @homecomputermuseum.computermuseum.social.ap.brid.gy next week)

@vandervalk.pro Is all ready for the last talk of the day at #netassemble "Dont let your access tokens be stolen" #security

Stephan van Rooij @svrooij.io · 02/10/2025

#netassemble first session by @wildermuth.com at #mstack "you can be bad everywhere" is the best quote from this talk so far. #community #dotnet

Maybe this image answers the question better: Really happy with these new sensors 🥇🚗 Using github.com/WJDDesigns/U...

Have a Volvo and using @home-assistant.io ? The Volvo On Call integration is broken. It has been replaced by a new integration that connects to the new api. I'm now creating the depreciation message.

Did you know #winget has almost 10.000 apps? Details on which packages got updated, and when? github.com/svrooij/wing...

Stephan van Rooij @svrooij.io · 19/08/2025

Trying to see if I can use #github #copilot to migrate #devproxy to use the new version of Unobtanium.Web.Proxy Ask it to do an inventory and migration instructions, before changing code. Good results so far! "Response modifying plugins should be migrated first" Living in the #future?

Road down memory lane, after 10 years I charged my #pebble Steel smartwatch again, and it still works! Getting the notifications from my phone! This is definitely one of the best smartwatches EVER 🤩✅⌚

Left to right Electric valve, regular shutoff valve, electric relay with zigbee.

Stephan van Rooij @svrooij.io · 30/05/2025

Automatically watering the garden with @home-assistant.io sure you can!! Ingredients electric valve, zigbee relay and some time. Check the picture to see the installation 👇

With this message from @jan-v.nl my training adventure started. I immediately decided that joining the Gymrace would be my goal for the next 10 weeks. Saturday I finished the incredible hard race in 1 hour 40 minutes. #health #fitness

Ever wanted to know what is going on in a scam website? Just check the source of the page. For easier hosting they won't be using any server side code. Just javascript

Crazy Amazon prime offer... If I pay extra they send one item later :D

Normally the #vattenfall chargers are pretty good, but today (when there seems to be plenty of solar power) they only produce 3.9 KW instead of 11 KW as advertised.... So instead of adding 27.5kWh I only got 8.9 kWh.... After 2h30m charging... #bummer #electric Car

Nice addition to security, when creating a new #Azure #Functions app in the portal, it suggests to use managed identities to access host storage and Application insights. Not supported for azure Files though (I know, NO CLICK OPS ALLOWED) #security #microsoft

010

Stephan van Rooij @svrooij.io · 18/04/2025

Trying to create a new Azure Functions App in #azure. Since it is dotnet-isolated I need to create a Linux app service. The portal then advises me to pick "Flex Consumption", great.... It is not available in the region I want.... Regular consumption it will be.

Stephan van Rooij @svrooij.io · 09/04/2025

Just checked the ratings of our #Microsoft Teams application "EducationHUB"... It allows access to digital learning materials through teams. Someone who does not like school "This app makes me do homework which I don't like." Great feedback I would say! And valid points 🫣

020

Stephan van Rooij @svrooij.io · 09/04/2025

Would you look at that #tado is switching to "device code flow" because it is more secure..... Yes it is more secure then resource owner flow, but why are they not going for authorization code with #PKCE? #fake #security support.tado.com/en/articles/...

Stephan van Rooij @svrooij.io · 09/04/2025

When creating a #Microsoft Teams app with sso authentication, you have to create an App ID URI in the format api://{the.actual.domain}/{appId} but did you know this is actually an array? Meaning you can have multiple versions of your teams app on different hosts 🤩💣 #developer #hack

Stephan van Rooij @svrooij.io · 08/04/2025

Finally #microsoft has changed this screen. To me it is better than the previous version. Better action description, better button text. #EntraID #intune What button should normal business users press? And what about consultants?

Automatically sign in to all desktop apps and websites on this device? Microsoft SSO, device management. Improved version

Super disappointed that we did not get true Seattle weather!! #mvpsummit Sunny and 22° Celcius! 😎

Stephan van Rooij @svrooij.io · 25/03/2025

I got this custom NFC tag, would you scan it if you saw me wearing it? All ready for day two of the #mvpsummit 2025 🤩

Stephan van Rooij @svrooij.io · 24/03/2025

Just arrived for my first day at #mvpsummit What questions do you want answered from what team? Let me know and I'll try to get your answers. #microsoft

Stephan van Rooij @svrooij.io · 20/03/2025

Random thought, use clippy to show web app notifications. Like the Azure portal notifications when a background thing is done. github.com/pi0/clippyjs This is totally happening #developer #joke #mvpsummit

Stephan van Rooij @svrooij.io · 17/03/2025

I need testers for my new #volvo integration for @home-assistant.io any takers? It does not ask for your password, but it redirects to volvo through the official authentication flow

Stephan van Rooij @svrooij.io · 15/03/2025

Running was never something I did for fun. Now I'm training for a hyrox event in May. Three weeks in and my interval training has a pace of +/- 6min/km when running and 9:30 for walking. Still no fun, but I'll manage reaching the finish of the Gymrace www.gymrace.com/en/the-race

000

Stephan van Rooij @svrooij.io · 12/03/2025

Working on a @home-assistant.io integration for #volvo. And thought, that device info car is a good place to put an image of the actual device. A car in this case or a product photo of the zigbee device? Nice idea?

Nothing more zen then a big party

Stephan van Rooij @svrooij.io · 07/03/2025

Is anybody at #microsoft aware of this? First one is with ipv6, second is without ipv6. That is the only change.... mcr.microsoft.com does not work over ipv6??? #sendhelp!!

000

Stephan van Rooij @svrooij.io · 07/03/2025

Microsoft container registry, it has a lot off containers that are used for development. But if you try to pull images when you have a working ipv6 address on your machine. Things break... Don't ask me how I found out 😉

Stephan van Rooij @svrooij.io · 07/03/2025

The best user interface ever. Three fields, firstname, Do not use, lastname With an instruction above it that we have to remove all spaces from our name and that we should not use the middle field for the lastname prefix we have in our country....

Stephan van Rooij @svrooij.io · 01/03/2025

How about "EACopy"? They had me interested by just the name 😜

Stephan van Rooij @svrooij.io · 27/02/2025

Agents? Build by ISV? Maybe why not!!

#devworld presentation by @laskewitz.io really looking forward to whether or not copilot studio is something for us. #conf
