As previously mentioned in the home monitoring re-write number four post, I have a number of Arduinos around the house that collect data and send the data using an HTTP POST to the home monitoring application. During the upgrade of the home monitoring stack, I decided to introduce Nginx to …
This year I upgraded the home monitoring suite in my house from a Wattson to a Splunk dashboard running on a tablet in the kitchen. The primary reason for doing this was that after getting the Tesla Powerwall, Wattson no longer was able to correctly state how much power was …
I’ve been using Keepass to store my passwords for years but it was only this year that I realised (yes, how could I not know?!) that the Auto-Type functionality can be customised to handle obscure login forms. Below are a list of some of the Auto-Types that I’ve created to …
Since getting the Tesla Powerwall installed, our trusted Wattson has not been able to display correct figures as it can’t tell if we are importing or exporting until the Powerwall is full. The Wattson displays a relatively static value of +150W indicating that we’re importing, yet the data from the …
In January I bought a Chromecast so that friends and family could cast videos onto the main living room TV. It’s a handy little device and when idle it displays lovely background images of nature, space and various other things. I don’t know why, but I never considered where it …
Last year I cancelled my ADSL connection and went 4G only on my EE 64GB contract. It’s been an interesting three months, so I thought I’d post this info in case anyone else was considering going 4G only. Background to why I went 4G only In August 2017, I noticed …
As you probably know from my blog, I have a number of Arduino’s around the house for monitoring household and weather metrics and I’m always looking for ways to add more devices and data sets. My dad happened to find a map one summer on blitzortung.org to view live lightning …
A few weeks back I received a request to add in the ability to select half days in the Retirement Countdown Clock app (https://blog.v-s-f.co.uk/2016/02/retirement-countdown-clock-app/) and I decided that this was a quick change that wouldn’t take too long, so why not 🙂 Well I made a complete mess up of …
I used to have a Microsoft Lumia 550 phone, which although basic just worked and really well. Unfortunately I’m a little clumsey and managed to drop it around a dozen times when getting out of the car at work (yeah, you’d think I’d learn). It managed to survive those drops, …
As mentioned in my previous post (see https://blog.v-s-f.co.uk/2017/04/home-monitoring-upgrade/), the first task I have is to migrate from HSQLDB to MySQL. Because the system logs data every minute while I have power in the house and I want to minimise downtime when I actually have a fully working upgrade, I’ve experimented …
I’ve been monitoring stats from my meter, weather and hotwater tank for over two years now (see https://blog.v-s-f.co.uk/2015/04/home-monitoring-home-made-reborn/) and the application now needs an upgrade. I now want to log more data from the weather station (temperature and humidity). This should be as simple as adding two new columns to …
This is the final part of setting up Elasticsearch, Logstash and Kibana using the official Docker Hub images. If you haven’t already read Part 1 Logstash or Part 2 Elasticsearch, it might be good to read them first. So far I have a running Logstash sending messages to Elasticsearch both …
It’s worth reading Part 1 Logstash first. So, today I had a chance to try out Elasticsearch on docker and it was semi easy to get it to work… the trickiest part was linking the Logstash and Kibana instances with the Elasticsearch instance. The trick is to name everything! So …
When I set up my new server back in May, I decided to try out Elasticsearch, Logstash and Kibana (E.L.K.) on it against the Aggregator (my PVOutput aggregating and uploading application) logs. It took me most of a day to get it installed, but because I followed a guide somewhere …
After a couple of years of reading about Spring Boot and never having actually tried it out, I thought now was the time to build a little example to find out how easy it is and also because I need a simple app for my E.L.K. project (more on that …
