I have added another project at https://github.com/GrahamCobb/TinyLab.
HumaxPower is a project to turn on my Humax PVR under command from another system. When it receives the command (a web access to
http://<arduino-IP>/poweron?humax=<humax-IP>) it transmits the Humax remote control POWER button infrared code. I plan to use this so that my Humax backups always work (even when it is turned off).
At the moment this is being prototyped on my TinyLab. But I hope to eventually move it to running directly on a standalone ESP8266-based board.
