Update on the sunpowered server

Update 2023: I no longer hosts those dashboards anymore and the server no longer runs in the form described. You could argue I still run sunpowered servers, as my new house has solar PV ;) Some, rather long, time ago I’ve added a custom python data acquisition and graphing to my sunpowered RaspberryPi installation on the balcony. Since then I’ve upgraded it to Raspi2 and ported the data thingy to influxdb + grafana. [Read More]

Adding voltage and current measurements to the sunpowered Pi

Remember my sunpowered Pi installation on the balcony ? The only indication I had, since recently, on how well the system is doing was an LED blinking red when battery was low. Not really helpful in making predictions or making measurements over the time. I’ve searched for simple ADC solution to hook up into Pi and allow for some voltage and power measurements. I’ve decided on ADC Pi, as it seemed very straightforward in its design and also comes with example python code. [Read More]

Sunpowered server setup

Remember my NAS ? It turned out great ! Very reliable storage, I had a disk failure once and haven’t noticed for some time because all the files were just there.

Only caveat ? Power consumption. This setup just eats Watts. About 50W constant power usage is not something you want to have turned on 24h/day. [Read More]
