    Running emoncms in a Linux container

    When I was renovating the house I currently live in, I picked up an EmonTx v3 and some clip-on current sensors from OpenEnergyMonitor.org so that I could monitor the house power consumption more accurately than just getting a bill every 2 months from my energy supplier (even with a smart meter installed, they only provide […]

The current VPS runs NGINX for web hosting (it was Apache until earlier this year), Postfix for SMTP, Courier for IMAP, and OpenVPN for VPN. Everything runs on one […]
