I’m using an iPad to control my RS150B, I always have to go to standby mode because if I power off when I go back to turn it on the unit won’t show up on my app. I have to manually turn the unit on and then re-pare the unit to the app.
Also the remote has never been able to communicate with the unit.
If you completely power off the RS150b, the WiFi transmission and reception will stop, so when you power it back on, you will need to search for the RS150b on your iPad again.
I will send you a video about connecting the remote control.
