CV Report
CV Report (G-Q-R)
Extended filtered report with data from two temperature sensors (OW0 and OW1). Ideal for cold chain applications, refrigerated transport, or environmental monitoring.
Temperature sensors use the 1-Wire (Dallas) protocol. To configure sensors, see Temperature Commands.

Temperature fields
Temperature OW0
| Field | Description |
|---|---|
| T | Temperature sign: + (positive) or - (negative) |
| UUUU | Value in hundredths of degree Celsius (eg: 2350 = 23.50C) |
| VV | Seconds elapsed since last valid reading |
Temperature OW1
| Field | Description |
|---|---|
| X | Temperature sign: + (positive) or - (negative) |
| YYYY | Value in hundredths of degree Celsius (eg: -0520 = -5.20C) |
| ZZ | Seconds elapsed since last valid reading |
If the age field (VV or ZZ) shows a high value, it indicates that the sensor may be disconnected or having communication problems.
GSM registration status (R)
| Value | Description |
|---|---|
| 0 | Not registered, not searching |
| 1 | Registered, home network |
| 2 | Not registered, searching |
| 3 | Registration denied |
| 4 | Unknown |
| 5 | Registered, roaming |
CSQ signal level (SS)
| Value | Description |
|---|---|
| 99 | No signal / Open |
| 0-30 | Signal level (higher = better) |
