Sorry if this has already been suggested but I would like to see some more device icons please. I am building an aquarium monitoring/control app that can display water/room temperatures as well as control relays for switching the lights on/off (via a schedule) and turn the heaters and filters (or pumps if you like) on and off using buttons for each relay. Therefore, can we please have device icons for heaters and pumps/filters.
Another thought - would it be possible to be able to build macros so that a single button could toggle one or more Raspberry Pi GPIO pins. I have one aquarium that has two filters and it would be cool if I could switch off both with a single button and do a similar thing with the lights on my two tanks.
