I am also pretty happy with the range of the flipper remote.
But there are two limiting factors, we need to keep in mind:
- The timing. Some Remotes needs to send in a very specific timing. The Flipper is not very good at perfect timings.
- The lighting around. In some environments the range will decrease, because of the used light source. Some lightbulbs are very disturbing for the IR signal, maybe based on point 1, the flipper IR is worse than the original remote.
I’ve experienced this light bulb issue once. To understand this issue, I’ve had ‘Settings - System - Debug: on’, so I was able to see in ‘Infrared - Debug’ a lot of ‘noise’ (means the flipper saw a lot of signals, that seems to be codes, even if it was garbage).
Some boring theory: Taking over TVs with Flipper Zero Infrared Port
The Video in “Why Frequency Modulation” explained how it should be avoided in general. But not what happens, when the bulb (or similar) itself ‘generating’ ir pulses/bursts.
