Lora weight data not stored

[antooni007]

Hi,

I'm trying to log sensor data over TTN to the lora_sensors api endpoint. While trying out the test payloads that are stated in the ttn-payload-decoder.js file, I noticed that all sensors are correctly logged on the beep app, except for the weight. It does not seem to store the weight data anywhere.

E.g., payload

1B0C4B0C44640A01012D2D040107D6

Stores the correct battery voltage (3.14V) and hive temperature (20.06 C), but the weight data is just ignored. To my understanding, a weight of 77.101 kg should be read from this payload. (The data is sent to port 3)

Is this a known issue or am I overlooking something? Thanks in advance for your response.

Kind regards,

@antooni007 Are you posting your weight values in the w_v field? If so, these values will displayed only after they have been converted to weight_kg which is normally done by the following Sensor Definition:

When using the BEEP Base hardware, the Bosche H40A load cell is calibrated with the BEEP Base App and this results in the "Offset" and "Multiplier" constants needed to calculate weight_kg values from the H40A's raw w_v values.

If you are using different scale hardware and you already know your calibrated weight values, simply post them to the weight_kg field, or create a new Sensor Definition on the app's Devices page that has input w_v and output weight_kg with offset = 0 and multiplier = 1.

Hi @ezja

I am indeed posting to the w_v field from my own scale hardware. But even when I create the sensor definition as you showed,

I don't get any weight data from the payload I sent it:
