Twitters new Toxic Rules – Goodbye Twitter!

If you think Elons Ego couldn’t hit a new low, think again…

Twitter just enforced new Rules:

I believe in free speech, a connected and open community, and the right to choose a platform of liking without being “punished” for it. Therefore, I can not and definitely will not accept the new terms of Twitter and will therefore terminate my Account effective immediately! But don’t worry – my main contact point was always here and not on Twitter πŸ˜‰ You can also:

Follow me on Mastodon: |
Follow me on LinkedIn:
Follow me on YouTube:
Follow me in the J-Forum: JChris929 (former CHS-929)
Send me a Mail: chs [at] ip4 {dot} de

What does this mean? Will you delete your profile on twitter?
Not at this time – My Twitter Account will be used as an archive for interested folks but will no longer post any updates or any news.

My new DayOne GREEN Book is out :)

If you love your garden-power-plant you shouldn’t look at my new DayOneGreen Book πŸ˜€
I had some free time and used it to write a teaser for my new book, which will hopefully be published in 2023 πŸ™‚

It is extremely important to me to pass on knowledge – that has always been my attitude.

In three examples I will show you how you can save a lot of money by virtualizing your lab environment and at the same time reduce your CO2 footprint – even more with the Juniper vLabs – even in small environments.

Incidentally, at #Axians we are constantly developing new ideas together with #JuniperNetworks to make networks even more efficient and “simpler”. At the end of the day, solutions must also be manageable for small teams – that’s a challenge we accept πŸ˜‰

Feel free to contact me if you have any questions.

Slides from Webcast: Creating a Juniper lab with EVE NG

Hi all, here you find (as promised) the slides from my last talk πŸ™‚
If you have any questions or encounter problems feel free to reach out to me πŸ™‚

For a quick “Juniper only” Lab you can also use the vLabs functionality to get started with JunOS and use your EVE-NG Server for your bigger, more customized Labs:

Juniper TechFest 2022 (virtual)

Next week, starting on Oct 17, TechFest2022 is happening πŸ™‚ Unfortunately still virtual – hopefully we will have local TechFests in-person next year. Nevertheless, this TechFest is packed with lots and lots of great Sessions (on-demand sessions). And this one is very special for me because for the very first time I’m not “just” a partner/visitor, but also a speaker – yup – little Christian is finally wearing a bigger pair of pants πŸ˜‰ Seeing my name next to my idols is somehow terrifying but also exciting at the same time πŸ™‚ I really hope you all enjoy the talk that I had with Ola and the mighty Steve Puluka about automation. Let me know in the comments what sessions you are interested in the most πŸ™‚

IoT-Nerd on PacketPushers

Hooray! The latest Episode of PacketPushers might be something that some of you have been waiting for: I had the honor to talk with Christopher Young and Ethan Banks about “Home IoT at scale”. It’s always fun to talk with like-minded professionals about implementations, limitations, security aspects, and basically how to push the limit of sensors more and more!

IoT will be a critical part of our everyday life – IoT is already happening if you like it or not – there’s no running away from it. This brings new challenges like IPv6-Security (and yeah – for this, you finally get to learn IPv6 – GREAT, right?), Wireless Security, Sensor Security, and Software / Patch management – something that the average User never had to deal with. But without it, he/she’s basically giving away the house key to the front door. Vendors are constantly working to bridge the gap between security and comfort for the user – curious to see what the future brings πŸ™‚

Building a Juniper EVE-NG Lab-Environment for daily usage – Part 3/3 – Slides

Wow – what a way to end our 3-part-series – a live presentation from one of the EVE-NG gods himself: the mighty Uldis πŸ™‚ If you missed this – you missed something!

As promised – here are the Slides from the last part of our series:

And of course the Video on YouTube (don’t forget to subscribe if you like the video – it helps a lot):

Huge shoutouts go to Uldis – the Insights and the help have been amazing – I cannot thank you enough πŸ™‚
And of course the best host in the universe: Christine – I really enjoyed the sessions.

Hopefully, I was able to embrace your interest in EVE-NG – especially if you want to start labbing with Juniper starting at 0€/USD (well except the server / Laptop you need lol).

Building a Juniper EVE-NG Lab-Environment for daily usage – Part 2/3 – Slides

Thank you all so much for attending the 2nd of our 3-Part-Series Session πŸ™‚
As mentioned I would love if you share your Labs in our Elevate Community:


And as always on my YouTube Channel (Remember to subscribe – cause subscribing makes you feel good) πŸ˜‰

Building a Juniper EVE-NG Lab-Environment for daily usage – Part 1-3 – Slides

Hi all,
thank you SO MUCH for an awesome first Session πŸ™‚

As Promised, here are the Slides from the Session:

The Video can be found on YouTube:

Looking forward to seeing you next week for Session 2 and the week after for Session 3 – if you have any questions (EVE, getting certified, general Juniper question), feel free to reach out to me anytime!

Shelly Failrates – Statistics from my SmartHome

Some of you also share the enthusiasm with me regarding Shelly – the others cannot be helped πŸ˜‰
Here are some stats that I created – hope this helps some folks. If you need more specific info just reach out to me πŸ™‚

The Plus-Series is not Part of the statistic since Allterco has to fix the Software first (Feature Parity with 1 PM, less power as promised, MQTT like the old shelly, because currently, they violate every best practice on the planet) before I install them – currently, the Plus Series is a (security) nightmare and I would strongly recommend installing the 1 PM instead of the 1 Plus PM. Hopefully, this will change in 2022 but in 2021 all possibilities to contact the dev team (mail, forums, tweets) did not work – either they really refuse to help outside of Facebook (which would be horrible for many reasons) or they refuse feedback and help at all…

Shelly 1 PM:
Installed Sensors until 12/2020: 217
Defective Sensors until 12/2021: 7
+ Device not responding anymore at all, 3 (2 of them after a power outage in our town)
+ Device is unable to save any settings, is in AP mode forever, 4 (1 of them after a power outage in our town )
Failrate: 3,23%

It just works and with just 7 Sensors to be replaced a year it’s perfectly fine for me. Now that the building phase in our town ended, I do not expect more outages and I also installed some UPS in the house πŸ˜‰

Shelly 2.5 (Roller-Shutter-Mode):
Installed Sensors until 12/2020: 11
Defective Sensors until 12/2021: 5
+ Device not responding anymore at all, 1
+ Device is unable to save any settings, is in AP mode forever, 2
+ Device likes to randomly “play” with the shutter, making me shit my pants every time, 2
Failrate: 45,45%

The Shelly 2.5 is the worst Shelly of them all – janky, not really reliable, and hopefully soon replaced by the Pro Series – I cannot say anything positive currently – they are just a pain to work with, and once they finally run you better never touch them again πŸ˜›

Shelly H&T:
Installed Sensors (Battery) until 12/2020: 17
Installed Sensors (USB powered) until 12/2020: 3
Defective Sensors until 12/2021: 0
Battery drains 10% every 2 Months
Failrate: 0%

Is there anything more to say than Failrate 0%? I guess not πŸ™‚ Excellent for statistics, reliable (even outdoors), and just fun to work with any gather statistics about Temp/Humidity everywhere.

Shelly Plug-S:
Installed Sensors until 12/2020: 15
Defective Sensors until 12/2021: 1
+ Device sounds like its working and switching the load, but does not (dead)
Failrate: 6,67%

Honestly: not bad. Wherever a 1 PM is not installed, you can quickly automate with the Plug-S.
Also just works and with 1 Device failing after 6 Months I’m fine with it.

Shelly RGBW2:
Installed Sensors until 12/2020: 3
Defective Sensors until 12/2021: 0
Failrate: 0%

Automating LED-Strips was never more fun πŸ™‚
Let’s hope that Allterco releases a Device in 2022 that can handle single-addressed-LED-Stripes πŸ™‚

Shelly Dimmer:
Installed Sensors until 12/2020: 2
Defective Sensors until 12/2021: 0
Failrate: 0%

Well – now that they don’t flicker anymore (patched Software Bug) they work really good πŸ™‚

Shelly Door/Window 2:
Installed Sensors until 12/2020: 7
Defective Sensors until 12/2021: 1
Battery drains 25% per Month (Vibration and Tilt activated)
Failrate: 14,28%

The only drawback is the battery lifetime. Some suggested disabling tilt or vibration – but hey – why? I want this device for this very reason. So either create one with a bigger battery, optimize the code, or don’t release it at all – just my 2ct πŸ˜‰

Overall, the Devices work very well, and besides some usual software hiccups that every Vendor has to deal with, I’m more than happy πŸ™‚ Looking forward to getting my hands on the i4 and the PRO Series in 2022 (already pre-ordered) πŸ˜€
