Low power wireless remote via arduino Answered

Hey all - I’m in the middle of a mental blank.

I have a project I am working on, that majority of the hardware is based around an arduino micro (sensor, couple of switches, Bluetooth for app interaction and all the relevant code) which will be mains powered. As an off shoot, I also want to include a battery powered wireless device to effectively trigger a latching relay for a simple on/off of a basic circuit, with a range of about 4 to 6 meters max https://www.applock.ooo/. Being a ‘safety warning’ type device, it’s not something that will be triggered often, but really need maximum standby time on the wireless receiver and to also play nicely with the arduino. So if anyone has any suggestions on an arduino friendly, simple wireless tx/rx pair, that has extremely low power draw on the rx side - I’d greatly appreciate the help. /https://scrabblewordfinder.vip/

Not hard to find informations, so I picked one from the top:
Digikey
Check the part about ANT....
There is other options as well of course especially in the area of sensors for weather stations and similar - they sometimes come with seperate modules so you could misuse the sending and receiving parts and the protocoals used for them are documented.
Even for ANT you wouldn't need an Arduino on the receiver side as you can use passive electronics on the output side of the module.
And the sender can be activated by the stationary Arduino.
I won't ask why for just 6 meters using wires is no option ;)
