HOBO TidbiT MX External Temp Data Logger
I did some packet sniffing and found that the temp comes from the last 16-17 and 18-19 bytes
I don’t know what the 20th byte is, maybe it’s the battery
float sensor_temp = raw1 / 93.2f - 46.8f;
float transmitter_temp = raw2 / 93.2f - 46.8f;
bait 16-17 = temp1 raw (little-endian)
bait 18-19 = temp2 raw (little-endian)
bait 20 = staatus / checksum / battery
| Pakett | Raw1 | Raw2 | Sensor temp1 °C | Transmitter temp2 °C |
