Teltonika FMC650 vs Rinho Smart IoT: Professional Trackers 2026
👉 Who this article is for: Integrators and heavy-duty fleet managers who need professional trackers with multiple I/O, advanced CAN Bus, and automation capabilities for complex operations.
⚠️ Disclaimer: This analysis reflects our perspective as Rinho manufacturers, but with a commitment to technical honesty. There's no perfect tracker for all cases — each project has different needs. Our philosophy is to help you choose the best for your specific case, even if that means recommending another brand.
The professional tracker segment for heavy vehicles has two interesting contenders: Teltonika FMC650 (successor to the popular FMC640) and Rinho Smart IoT. Both target fleets that need CAN Bus, multiple I/O, and advanced capabilities. But they have very different approaches.
Complete Comparison Table
| Feature | Teltonika FMC650 | Rinho Smart IoT | Advantage |
|---|---|---|---|
| Cellular connectivity | LTE Cat 1 + 2G | LTE Cat 1 + 2G | Tie |
| WiFi | ❌ Not available | ✅ Integrated | Smart |
| BLE for sensors | BLE 5.0 | BLE 5.0 | Tie |
| GPIO | 4 In + 4 Out + 4 Analog | 9 DIN + 7 AIN + 3 Out | Smart |
| CAN Bus | 2x J1939 + J1708 + K-Line | CAN (J1939, OBDII, IESCAN) | See note* |
| Event engine | 12 fixed scenarios | 196 programmable rules | Smart |
| Serial port | 2 (RS232) | 1 (TTL 3V3) | FMC650 |
| 1-Wire | 1 | 2 | Smart |
| Dual SIM | ✅ Yes | ✅ Yes | Tie |
| Backup battery | 550 mAh (Ni-MH) | 1300 mAh (Li-Ion) | Smart |
| Power supply | 8-32V DC | 8-38V DC | Smart |
| IP protection | IP54 | IP30 (indoor installation) | FMC650 |
Note on GPIO: The FMC650 has more dedicated I/O (4+4+4). The Smart has 9 digital inputs + 7 analog inputs + 3 outputs, offering significantly more total I/O capacity.
CAN Bus: More interfaces vs More flexibility
Note on CAN: The FMC650 has more physical interfaces (2x CAN + J1708 + K-Line). This is useful for:
- Old American vehicles using J1708
- European vehicles with K-Line
However, Teltonika has the advantage of years of reverse engineering with extensive databases of profiles by make/model/year. If your fleet is homogeneous with supported brands, initial setup is faster.
Rinho Smart covers the main standards: OBDII, J1939, and IESCAN (Mercedes-Benz trucks). For proprietary parameters or vehicles without pre-configured profiles, CXECU allows defining custom CAN readings — flexibility that Teltonika doesn't offer.
CAN Summary: FMC650 wins in number of interfaces and pre-configured profiles. Smart wins in flexibility for custom configurations and unofficially supported vehicles.
WiFi: The constant differentiator
Like the entire Rinho line, Smart includes integrated WiFi. The FMC650 doesn't.
In heavy vehicle fleets, this is especially relevant for:
- Trucks in rural areas (Argentine pampas, Brazilian cerrado) where Starlink is the only viable connectivity
- Data download without consuming mobile data at depots
- Integrated captive portal: Smart can serve a configurable web page where drivers perform check-in, pre-operational inspection, or confirm deliveries — all connected to the 196 rules engine
BLE Ecosystem: Wireless sensors for complex operations
Smart IoT includes factory BLE 5.0 with 4 fixed positions for sensors with detailed data, plus a BSW wildcard system that allows expanding monitoring to dozens of sensors through smart grouping. Compatible with Mokosmart, Escort, and iBeacon/Eddystone — ideal for heavy transport operations with multiple monitoring points.
Combined with the Smart's 9 digital inputs and 9 analog inputs, you have a sensing capacity that no competitor matches in this segment.
| Mokosmart Sensor | Heavy transport application |
|---|---|
| Rinho Condition (L02S) | Multiple temperature zones in refrigerated, virtual trailer coupling, door opening |
| Rinho ID Band (W6) | Driver identification, start control, SOS button, fall detection during loading/unloading |
Success case: Virtual trailer coupling
Without cables or perforations in the fifth wheel, the system automatically detects which trailer is coupled to each tractor. Useful for fleets where one tractor can pull multiple trailers in a day. Read more about virtual coupling with Mokosmart.
Multi-zone cold chain monitoring
With 3-4 L02S sensors distributed in the refrigerated container, you can monitor main chamber temperature, antechamber, and product, all integrated with the 196 rules engine for smart alerts:
IF temperature_zone1 > 8°C OR temperature_zone2 > 8°C
AND compressor = ACTIVE (via CAN)
AND condition_time > 10 minutes
THEN → CRITICAL Alert + SMS + emergency profile

Event engine: 12 vs 196
Same story as other Teltonika models. The FMC650 has 12 predefined scenarios. The Smart has 196 programmable rules with complex logic.
Example: Comprehensive refrigerated truck monitoring
IF chamber_temperature > 8°C
AND compressor = OFF (via CAN J1939)
AND rear_door = CLOSED
AND vehicle_moving = YES
AND condition_time > 10 minutes
THEN
→ Activate cabin buzzer (DOUT1)
→ Generate CRITICAL priority event
→ SMS to logistics supervisor
→ SMS to operations manager
→ Switch to "Emergency" profile (report every 30 sec)
In FMC650: Impossible. There's no way to combine 5 conditions from different sources with 5 different actions.
In Smart IoT: One rule with direct configuration. The event engine was designed for these cases.
Protection and robustness
| Feature | FMC650 | Smart IoT |
|---|---|---|
| IP protection | IP54 (splashes) | IP30 (indoor) |
| Backup battery | 550 mAh (Ni-MH) | 1300 mAh (Li-Ion) |
The FMC650 has IP54 protection, designed for chassis installations. The Smart IoT with IP30 is oriented for protected installations inside the cabin, common in vehicles where tampering protection is a priority.
In backup battery, the Smart has a significant advantage (1300 mAh Li-Ion vs 550 mAh Ni-MH), offering ~2.4x more capacity.
When NOT to choose Rinho Smart
For transparency, here are cases where Teltonika may be a better option:
| Situation | Why choose FMC650 |
|---|---|
| Need J1708 or K-Line | Interfaces Smart doesn't have |
| Very exposed installation | FMC650 is IP54, Smart is IP30 |
| More RS232 ports | FMC650 has 2 vs 1 TTL |
| Already have Teltonika ecosystem | Maintaining operational consistency |
| Fleet 100% with Teltonika CAN profiles | Faster setup |
When to choose each one?
Choose Teltonika FMC650 if:
- You need J1708 or K-Line interfaces for old vehicles
- Your fleet is homogeneous with CAN profiles already available in Teltonika
- You need more RS232 ports (2 vs 1)
- You already have infrastructure and knowledge of the Teltonika ecosystem
Choose Rinho Smart IoT if:
- You need more I/O (9 DIN + 7 AIN + 3 Out)
- WiFi is critical for your operation (Starlink, data download)
- You want to integrate wireless BLE sensors (virtual coupling, temperature, drivers)
- You want complex automations (196 programmable rules)
- You have mixed fleets or vehicles without pre-configured CAN profiles
- You value technical support in Spanish and the same timezone
Conclusion
FMC650 is a solid professional tracker with good variety of CAN interfaces. Smart IoT offers:
- ✅ More I/O (9 DIN + 7 AIN + 3 outputs)
- ✅ Integrated WiFi
- ✅ Complete BLE ecosystem for wireless sensors
- ✅ Much superior event engine (196 vs 12)
- ✅ ~2.4x larger battery (1300 vs 550 mAh)
- ✅ TTL serial port for additional integrations
If your fleet is simple and homogeneous, the FMC650 works well. If you need flexibility, automation, and advanced connectivity, the Smart is the most complete option.
