Let's play with technology

The Atari ST/STE/Mega ST/STE computers had dedicated monitors to support the graphics modes that were implemented by the engineers who left Commodore with Jack Tramiel in 1984:

  • mono – black and white – 640×400 resolution, 35KHz horizontal frequency, 71Hz vertical frequency – which is available o...

RGBtoHDMI for Atari ST/STE is a great project to add modern video to an old home computer. How old? Atari ST is almost 40 years old (today: 37), based on a 16 /32 bit MC68000 processor with 8MHz clock and a maximum of whole 4MB RAM. Nowadays, almost every new micro-controller is much faster and more capable, but this is not what makes it iteresting – that would be the nostalgia. Thanks to this “noSTalgia”, new versions of games are still created today – i.e., Lotus Turbo Challenge

My Raspberry Pi 1B+ has been opening garage and letting me know of the conditions for work nearly 4 years. Recently I’ve decided to replace this 2014 small board computer (SBC) with newer version. I’ve also looked at better (the principle Keep it Small and Simple – KISS) solutions that became available – i.e. ESP Easy on ESP8266 (controlling the relay and reading the contact switch is not too much for this platform, even with addition of environmental sensors), but after some thinking – the option of leaving the Raspberry Pi in place won because of one additional perk that I wanted to handle – a classic water meter. Yes, such an old analogue water meter. Fun!

Grafana is the answer to the nagging question we’be been asking ourselves over the years – how to quickly and nicely present our data gathered from devices. InfluxDB on the other hand is the database that is as easy and simple to use, thus making it an ideal candidate for this job.
Let me show you how to quickly and easily put our data from domoticz and other devices to InfluxDB and then using Grafana – display in much more useful way than default domoticz graphs do.

Update: 2019-07-10: PhantomJS i Grafana 5/6.x na ARM

The new Raspberry Pi 4 is a very interesting change in the direction of the original project. Why? I will summarize what we already know, right after the premiere:

Tauron Polska Energia as one of several operators - provides its customers with remote readings of received energy from newly installed electricity meters with a wireless module - most often labeled AMI, Smart or 3G. Currently, in the first half of 2019, residents of Wroclaw and surrounding areas (AMI Plus program) can use such meters.

UPDATE: April 2020 - Tauron has changed the data format - it is now CSV. Please update (Github - clone)
