Did anyone already wrote a decoder function for the format of the RisingHF RHF1S001 sensor node?

If not, I’m willing to write one and share it, but I have some troubles to get started writing the custom decoder function.

This is the payload which arrives at TTN: 010C6E740F008224C4. The documentation says: ![](https://www.thethingsnetwork.org/forum/uploads/default/original/2X/e/e47f3a020b1ee30e8f57bbddddffc656ec0ef108.png) ![](https://www.thethingsnetwork.org/forum/uploads/default/original/2X/e/e41938c8eb2423fee5983ae88ccb7f87169a77c4.png) ![](https://www.thethingsnetwork.org/forum/uploads/default/original/2X/0/0f1e1b52c7800df7288c9ac47009fb0aded34878.png)

Try this?

```
function Decoder(bytes, port) {
var obj = new Object();

//temp
var tempEncoded=(bytes[2]<<8)|(bytes[1]);
var tempDecoded=(tempEncoded*175.72/65536)-46.85;
obj.temp=tempDecoded.toFixed(2);

//humidity
var humEncoded=(bytes[3]);
var humDecoded=(humEncoded*125/256)-6;
obj.hum=humDecoded.toFixed(2);

//period
var periodEncoded=(bytes[5]<<8)|(bytes[4]);
var periodDecoded=(periodEncoded*2);
obj.period=periodDecoded+" sec";

//battery
var batteryEncoded=(bytes[8]);
var batteryDecoded=(batteryEncoded+150)*0.01;
obj.battery=batteryDecoded.toFixed(2);

return obj;
}
```

Thanks a lot! Works like a charm…
