Arduino : Monitor Solar Panels Production (Part 4)

Image
Background We did a lot of very interesting work so far and we already have a nice working product. However, I have the feeling it is lacking in few aspects. Especially the visibility of its own status and something showing it is working and reporting the data correctly.

ChatGPT : The Future is Now

Image
Background Yes, I did not resist to share an article on the most discussed topic of the last month ... ChatGPT, the new all terrain tool that address any questions. Instead of writing about something you already know, I let ChatGPT to create this blog post. I asked  questions and I merged the answers below. This is mind blowing ! Let me know in comments what you think about ChatGPT and the generated content. Please Keep in mind that I only layout the text, the entire content is AI-generated.

Wallbox : API Episode 3

Image
Background I've received some very positive messages related to my posts about the Wallbox API. This is very rewarding and I would like to thank all the people who are reaching out 🙏🏻. In the comments, I've see people asking for API to restart the unit remotely. Since API only limit is the sky, let's see what can be done.

Rubrik : How to run a script with 2FA enabled

Image
Background Recently, Rubrik is enforcing the 2FA authentication (Multi Factor Authentication). This is a great security feature that minimizes the risk of unauthorized access to your environment. But how does it work within a script ? There is no way to enter a 2FA code when running a script every day at 2 am for example. The 2FA is enforced starting at CDM v 8.0.2 with a 3 month grace period to allow the customers to adjust their security.

Domoticz : Monitor Solar Panels Production (Part 3)

Image
Background Since the lovely box is now created , let's see how we can improve the reporting. ThingSpeak and MATLAB cannot provide me with the relevant reporting - simply because I need time to learn how it works and honestly, I have something else in mind. I have a home automation platform at home called Domoticz, may be I can get something out of it !

3D Printing : Monitor Solar Panels Production (Part 2)

Image
Background Now that we have created a device to measure our solar production , it is the perfect timing to improve it. In the previous post, all the electronic components are exposed to the dust and anyone can potentially disconnect the components - intentionally or not. It would be nice to secure everything in a custom made enclosure !

Arduino : Monitor Solar Panels Production (Part 1)

Image
Background With this article, I'm actually starting a new section on my blog : some electronic builds. I have solar panels on my roof since 2009 and this is a real benefit. I mean, not only the environment is happy, my wallet as well. Price of electricity these days are crazy and this is a relief to count on this extra "free" production. The problem is : my inverter is old and provides no means to see how my production looks like during the day. I can only check the production since they have been in production (I have a so called green meter). Plan is to create a cheap mean to measure and log the production.

Rubrik : Active Directory Recovery

Image
Background Have you ever tried to restore a Microsoft Active Directory object ? Painful mmh ? I tried as well and did not found any suitable tool that can definitely nailed it correctly without having a massive corruption after couple of days. Then, I heard Rubrik was able to deal with that. This is about the right time to give it a try !

Nutanix : CVM stuck into Phoenix

Image
Background Last night, I was in my monthly upgrades process for my clusters. I was about to catch up with all the versions. I was about to start the last run of patches, so I ran the LCM inventory for the last time. Of course I was doing something else in parallel - LCM is so time consuming, you'd better parallel tasking. When I came back to the LCM inventory screen, I saw 6 pre-checks errors : Cassandra down, network down, connection timeout, .... Most scary : node removed from Metadata Ring.

Wallbox : API Episode 2

Image
Background In the previous episode about "using API and Wallbox", we have seen some interesting ways to interact with the charger. In this episode, the goal is to add some more practical examples. Indeed, if you are following my GitHub repo on this topic, I have added some functions for pausing, resuming the charging session as well as locking and unlocking the charger. Also, I can set the charging power to a certain number of Amps. Let's see this in action !
