You may wish to note that there is a US version of the Chroma 74 which runs in the 900MHz band. These units will have "FCC ID: VC7120-0157" on the back label.

Specifically they run at 902.5 to 927.5 MHz per FCC documents

It seems the C1101 transmitter recommended will work with this as well. I ordered a few, but haven't tested them yet.

Hey, the Displays can do both 868 and 915mhz,

they will listen on a set activation channel.

the 915mhz is also supported with the ESP32 firmware.

That is great news! All the talk about 868MHz made me think there might be a regional version. Excited to try them out.

Thanks for the reply and all of the details!
