Lilygo 915mhz support - New User


New user here, I have an existing 433mhz Lilygo device which I was able to get set up with OpenMQTT, and I loved it so much, I decided to buy the 900mhz version of the device for monitoring my municipal water usage which transmits via SCM Plus which I currently do with an SDR USB adapter plugged into a Raspberry Pi.

Firstly, it appears I need to change the frequency on the device as the recompiled version has 433.92mhz:
I did this via the console:

commands/MQTTtoRTL_433 {“mhz”:915}

Unfortunately, I don’t get any results at all, unlike my USB adapter.

Secondly, when I do a reboot on the device, it resets the device back to 433mhz.

So my two questions. 1) How to I make my device stick to the 900mhz frequency and 2) Am I doing this incorrect, or something else?

Thank you for your patience!
