AC Contoller 69 questions

Hope everyone is having a wonderful day!
I’m considering getting an AC Infinity controller version 69. The one that runs wifi and 4 ports. I’m sure there’s a few growmies out there that have them. I’m curious about range. As in distance… How far can these things be from a hub and still lasso? I’m quite the distance from the house, and need to work out the technicals before taking the leap.
Any help or suggestions will be much appreciated!!

Use your Phone to test strength x distance or buy a repeater/extender or a shitty old router and hack it into a repeater. I forget the software I used until I get home, I have repeaters in the Garage, garden shed, basement etc. I’m 50 miles away at work and I can control my tent via wifi from here. 69Pro Wifi/BT model.

Remembered, Its DD-Wrt

Maybe @Newt ?

Mine is Bluetooth, which covers my entire house - but I have a small house.

I’ll clarify. The phone app connects to the Wifi in my office(50mi away), then connects me via the internet and ACI redirect/routing to my controller on my grow Wifi. Typical of all these gizmos, like the my Pulse Pro …but deserved a clarification note.

A repeater is definitely needed for this task
