Additional icons

[pl-komuch]

It is great to see the list of icons available for assignment to devices expanding. If possible, I would like to request the addition of the following icons in the next batch:

• air conditioner
• boiler or heating unit
• single-board computer (RPi, etc.)

[gnacho]

Landed on main: air conditioner, boiler/heating and single-board computer now classify to their own types with dedicated icons (AirVent, Heater, CircuitBoard). Purely additive - devices already classified keep their current type and icon. Ships with the next release.
