Decoding ELSYS ERS Sensor

Hello community,
I am operating an ELSYS ERS sensor on a Chirpstack server. The raw data supplied by the sensor looks like this:
01010d02400400000500070e61
If you decode this data (for tools see Elsys Payload – en
)
this data set comes out:
{
“temperature”: 26.9,
“humidity”: 64,
“light”: 0,
“motion”: 0,
“vdd”: 3681
}
Unfortunately, I have not yet found the right JavaScript for this sensor.
Can any of you help?
Which tool do you use to check if your javascript decodes the raw data of the sensor correctly?
Thank you very much
