Rules Engine - increase/decrease numeric property by a fixed increment

[Arzachena]

1.I have a Hue bulb and a Hue on/off /dimmer switch. In the Rules screen I have 2 rules so that the on and off buttons control the bulb state. But when I try to set up rules for the “increase/decrease brightness” buttons (event 2 and event 3) the bulb thing only allows me to set the brightness to a certain fixed level. What I need is to be able to set it to its current level + a percentage.

This would be also very helpful for me! Are there already plans to implement this?

Additionally I'd like to be able to toggle binary states for a combined on/off button, e.g. what you can find on the Ikea Tradfri remote: https://www.ikea.com/gb/en/p/tradfri-remote-control-30443124/

Try using the "Followers" add-on. Then you can specify a range from one thing to be applied to a range on another thing. The ranges don't even need to match.

We're trying to keep the rules engine UI as simple as possible. I'd say that a reasonable goal for the rules engine UI is that 80% of rules can be set with the simple drag and drop UI, and the other 20% require a custom add-on to do something special. My gut feeling is this use case of increasing/decreasing the value of a property by a fixed increment falls into that 20%. But if anyone has ideas for how to incorporate this into the UI without adding too much complexity then I'd be happy to review designs.
