In March I posted about my search to monitor the ink fill levels of my new printer.
Having a dashboard with the absolute ink levels is nice. Done that.
I still wanted to understand the usage over time. Due to my lazy programming I have been sending the data to influxdb since March without even noticing, since this is done with all useful data automatically. I just had to look for the data and display it in grafana.
The black ink is displayed in grey. The magenta ink is exactly the same as the yellow one, therefore hidden behind the yellow line. Looking at the data spanning half a year, I will need to buy new black ink in about a year or so. The printer (Epson ET-2750) is probably going to die sooner than the coloured ink runs out.
