Question

Is there a way to monitor incoming Supply Voltage and Current consumption on 955 or other Routers. This function is required for when the 955 is located in remote locations that are using Battery and Solar Power.

Answer 1

It is possible but you need a contoler that you need to hook up to the tectonics and it will send data over Modbus or MQTT.

Thanks Dako, yes of course with external device it is possible and I am aware of this option.my question is about "self monitoring" to avoid external hardware. Maybe Teltonika can add this as a feature request.

It's doable, but you'll need a controller that you connect to the tectonics and that sends data through MQTT or Modbus.

Hello,

Thanks for contacting TELTONIKA | Crowd-support forum.

Please find below RUT955 power consumption values in different states of operation:

https://wiki.teltonika-networks.com/view/RUT955_Power_Consumption

The router has a 4 pin power socket and can be powered by a 9-30 VDC power supply unit (PSU).

The device is designed to accept input voltage of up to 30 VDC peaks, high voltage power supplies can harm the device. If you want to use high voltage power supplies it is recommended to also use additional safety equipment to suppress voltage peaks from the power supply.

If you’re using Quectel, you can read ADC Value by typing the following command:

gsmctl -A 'AT+QADC=0'

If you’re using MEIG, you can read ADC Value by typing the following command:

gsmctl -A 'AT+ADCREAD=1'

Hello,

is it possible to forward the voltage cyclic to an local mqtt broker?

Thank you!

Hello,

@unox It would be possible to achieve this by utilizing a custom Modbus register. Then simply set up Data-to-Server as Data Source → Modbus, Protocol → MQTT and specify what you'd like to send.

For the custom register, the example provided in the article could be modified to the following (for Quectel modems):

#!/bin/ash while true do gsmctl -A 'AT+QADC=0' > /tmp/regfile  #where data will be stored sleep 5 done

Let me know if any more information is needed!

Best regards,
