There are many examples of Aqara door/windows (MCCGQ01LM or MCCGQ11LM) sensors to make rain sensor, or wireless button or lock sensor.
Sometimes at night I happen to open windows or doors when the alarm system is activated and this causes the siren to sound.
I would like to build a wireless status LED to be glued to doors or windows to see if the alarm is armed.
To do this I would need to replace the LED with a larger and more visible one and be able to control the LED from the home assistant when the alarm system is activated and turn it off when the alarm system is deactivated.
Some suggestion?
