My new DayOne GREEN Book is out :)

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

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 😉

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 🙂
If you have any questions or encounter problems feel free to reach out to me 🙂

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: https://jlabs.juniper.net/vlabs/

Juniper TechFest 2022 (virtual)

Next week, starting on Oct 17, TechFest2022 is happening 🙂 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 😉 Seeing my name next to my idols is somehow terrifying but also exciting at the same time 🙂 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 🙂

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 🙂

Shelly Failrates – Statistics from my SmartHome

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

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 😉

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 😛

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 🙂 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 🙂
Let’s hope that Allterco releases a Device in 2022 that can handle single-addressed-LED-Stripes 🙂

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 🙂

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 😉

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

2022 Goals

      1 Comment on 2022 Goals

What are your goals for 2022? This year I’m a bit early with my planning but the early bird catches the JNCIE-ENT, right? 😉 Looking forward to hearing about your goals for next year – let’s motivate each other!

The JNCIE-ENT will be my primary goal in 2022 – no doubt about it. I’m really looking forward to this one because the topics cover 99% of my day job (+1 for ditching Multicast and putting EVPN in instead) and therefore the training also has a huge impact on my job as well. As you all know the JNCIE-Certification is the highest one you can achieve for a specific Track (SEC, ENT, DC, SP, and Cloud) and the exam is extremely close to real-world scenarios if not spot on! The exam is (unlike many competitor exams at this level) not there to ask you scenarios that would never happen just for the sake of asking them – the JNCIE checks if you can do a daily job (from design to implementation) and being able to troubleshoot issues. You have 6 hours (I still miss the 8h exam…) to complete it in front of a proctor – that makes this exam so special – you can feel the pressure. But that also makes it fun. But the best thing is the way towards the JNCIE: Interacting with others, countless lab nights, reading a gazillion of books and whitepapers – I just love it 🙂

The JNCIP-SP and JNCIP-Cloud are the remaining 2 professional certifications needed for me to get the “All-A, All-S, and All-P” status – meaning having ALL Associate, Specialist, and Professional certifications that Juniper currently has to offer 🙂 I would bet any sum, that we will also see a JNCIP-MistAI (and possibly even a JNCIE-MistAI) at some point – but I guess not before 2023 so I guess I’m “safe”. If not, Marvis took over the planet and created the exams itself 😀

With the AATP I have full access to all Courses, making the learning of new Topics WAY easier because I can simply sit in a course with the topic of my interest and get training from the best proctors out there without having to worry about increasing additional cost. You can find more Infos here: https://learningportal.juniper.net/juniper/user_activity_info.aspx?id=ALL-ACCESS-TRAINING-PASS-HOME

But I’m curious: What are your 2022 goals? Any specific Tracks? Any new Technologies?
Let me know in the comments or on Twitter and share your goals with the world 🙂
