SRFBHADiscovery module on mqtt topic SYStoMQTT - should RF work?

Hi, on theSonoff RF Bridge, with .bin flashed v 0.9, I get, every 2 min, on the topic
home/OpenMQTTGateway/SYStoMQTT , the following: {"uptime":360,"freeMem":45104,"rssi":-72,"SSID":"TheStorm","modules":"SRFBHADiscovery"}.

Should RF work with this module only?

What does the standard SONOFF_RFBRIDGE_OpenMQTTGateway_V09.ino.bin have uncommented in User_config.h, only #define ZgatewaySRFB "SRFB" ?

Problem is, I am sitting 4 old types of remotes, and I am getting no response back from RF, want to ensure the bridge is correct before buying other remotes to test.

Yes exactly

Did you put the internal switch to ON after flashing?

Yes. Let me go pick up another RFBridge, and test again.
