There is also a discussion on the various 433MHz radio formats at: > [@Emon Tx V4 and 433MHz Radio Formats](https://community.openenergymonitor.org/t/emon-tx-v4-and-433mhz-radio-formats/22085): > > I was wondering how many RF data formats there are at the moment? I have some questions, and as I am a bit confused, | would be grateful for any help! As far as I can tell, there are three named versions: Jeelab (called classic or legacy) rfm69n (used when running emonLibCM on the original emonPI, with compatible versions available for other units) see [The emonPiCM](https://community.openenergymonitor.org/t/the-emonpicm/18173) LowPowerLabs RFM69 (available in the emonTx V4 and the current emonBase) Is this correct? Are any of them compatibl… which may be useful … Also: [https://docs.openenergymonitor.org/emontx4/technical.html](https://docs.openenergymonitor.org/emontx4/technical.html) The various Arduino RF libraries are available in the repositories at > **[OpenEnergyMonitor](https://github.com/openenergymonitor)** > > Open-source energy monitoring tools to help us relate to our use of energy, our energy systems and the challenge of sustainable energy. - OpenEnergyMonitor --- _[View the full topic](https://community.openenergymonitor.org/t/help-with-versions-of-code-on-the-rfm69pi/24169)._
