Describe the feature you want
Sorry bad English. I think that is cool to implement a function like HOTEND_IDLE_TIMEOUT, but for Hot Bed. Actually, this only verify the temperature hotend. It could be better, (for security too), if have a option for Hot Bed, avoid that a hot bed stay warming up forever. Suppose, for example, that I manually set 110º ONLY for the Hot BED, and not for hot end, and forget that I did that, it will stay there heating up, since the function HOTEND_IDLE_TIMEOUT will not be activated.
If this already exists, could you show me where and how? Thank you.

Bed should get turned off at same time hotend idle timeout
look at void HotendIdleProtection::timed_out()
Marlin\src\feature\hotend_idle.cpp
void HotendIdleProtection::check() {
const millis_t ms = millis(); // Shared millis
check_hotends(ms); // Any hotends need protection?
check_e_motion(ms); // Motion will protect them
// Hot and not moving for too long...
if (next_protect_ms && ELAPSED(ms, next_protect_ms))
timed_out();
}
// Lower (but don't raise) hotend / bed temperatures
void HotendIdleProtection::timed_out() {
next_protect_ms = 0;
SERIAL_ECHOLNPGM("Hotend Idle Timeout");
LCD_MESSAGE(MSG_HOTEND_IDLE_TIMEOUT);
HOTEND_LOOP() {
if (cfg.nozzle_target < thermalManager.degTargetHotend(e))
thermalManager.setTargetHotend(cfg.nozzle_target, e);
}
#if HAS_HEATED_BED
if (cfg.bed_target < thermalManager.degTargetBed())
thermalManager.setTargetBed(cfg.bed_target);
#endif
}
Bed should get turned off at same time hotend idle timeout
Yes, but it relies on HOTEND_IDLE_TIMEOUT
being enabled and above the set point. There’s no “BED_IDLE_TIMEOUT
”-like feature where there’s a timeout if only the bed is heated.

Exactly.
