Accessing Data and Controlling Relays on TPDIN-Monitor-WEB2 via HTTP

  • You can access the real time readings and control relays on the TPDIN-Monitor-WEB2 via HTTP.
    To access the real time readings:
    The xml result will look like this:
    <ctrt>07/26/2017 07:05:31</ctrt>
    <uptime>0 days 00:02:27</uptime>
    ct10: relay 1 state
    ct11: relay 2 state
    ct12: relay 3 state
    ct13: relay 4 state
    pot0: I1 current
    pot1: I2 current
    pot2: I3 current
    pot3: I4 current
    pot4: V1 voltage
    pot5: V2 voltage
    pot6: V3 voltage
    pot7: V4 voltage
    pot8: external temperature
    pot9: internal temperature
    ctrt: device time
    uptime: device uptime
    To Control Relays:
    ctl=0: cycle relay 1
    ctl=1: cycle relay 2
    ctl=2: cycle relay 3
    ctl=3: cycle relay 4
    ctl=4: toggle relay 1
    ctl=5: toggle relay 2
    ctl=6: toggle relay 3
    ctl=7: toggle relay 4
    Example: HTTP://controls.cgi?ctl=0   To cycle Relay 1

I was updating the firmware on the TPDIN-Monitor-WEB2 and now I can't access the unit?

  • A communications problem during upgrade may have caused corruption in the flash memory or the "Upgrade and Reboot" button was double clicked or pressed twice. Follow these steps to recover:
    1. Press and hold the reset button while powering up the unit.
    2. Release button as soon as you see a green Link LED on the RJ45 connector.
    3. Access the unit via the Discovery Tool or on it's previous IP address and immediately go to Upgrade and re-load the firmware. Be careful not to double click the "Upgrade and Reboot" button.

My real time clock isn't updating on my TPDIN

  • 1. Make sure the unit is connected to the internet
    2. If set for static IP check to make sure on Network Page:
        Default Gateway address = address of your router
        DNS Address = valid DNS address. Use Google DNS address if you don't have alternate DNS.

I cannot send email from my TPDIN series product. Non-SSL?


The TPDIN™ series of products may not support encrypted email (non-SSL / TLS). Most mail servers like GMAIL require encrypted email (SSL/TLS).


In order to send email alerts with the TPDIN™ series of products that don't support SSL/TLS you will need to be able to send non encrypted email via SMTP port 25. 

You can sign up for a free account at TurboSMTP orJangoSMTP or GMX Mail. These free email servers allow non encrypted sending of emails.


Another option is using Google's non encrypted SMTP server on port 25. The SMTP server address is:

This SMTP server will only allow sending to a gmail address. When using this service leave the user name and password fields blank. Make sure to check the box that says "Use user name as from field".

How can I reset my TPDIN product to factory defaults?

  • TPDIN-Monitor-WEB: Hold down the reset button while powering up the TPDIN-Monitor-WEB and hold for 15seconds. Release reset button.
    The unit should be back to factory defaults. Note: Resetting to factory defaults doesn't affect the IP address settings.

    TPDIN-Monitor-WEB2: Power up unit. Wait at least 20 seconds. Press reset button and hold for 10 seconds to reset to factory defaults. If reset button is held for longer than 30 seconds, the unit will roll back to the last stable factory firmware. Only use this if the unit has an unrecoverable error.

    TPDIN-SC48-20: There is a button on the top of the controller labeled FACTORY DEFAULT. Pressing and holding this button for over 5 seconds will reset to factory defaults.

Saving Power via Time of Day and Periodic Power Cycle Control – TPDIN-Monitor-WEB

  • Problem: Sometimes your remote power system doesn’t have enough power to keep your equipment alive for 24hrs per day and you really don’t need, for example a camera, to be powered on at night. Other times you want to be able to reduce your investment in solar panels and batteries because your equipment only needs to be powered up during certain times of the day. 
    Solution: With the TPDIN Monitor you can program Relay 1 (CH1) and Relay 2 (CH2) to operate only during certain times of the day. To set the unit to power up equipment only during certain hours connect one side of the power going to the equipment through Relay 1 (CH1) or Relay 2 (CH2).



    Then set the Time Control for an ON time and an OFF time. The equipment will turn on at the ON Time and turn off at the OFF time. 


    This will reduce the daily power consumption by only turning on the equipment during the hours that it is needed. In the example on the right, the Relay 1 will turn the equipment on at 6AM and off at 9PM.

    You can also combine both time of day control and periodic control by using both the Ping Control and Time Control. For instance I may want to power up my camera and wireless only once every 30 minutes during the daylight hours for 3 minutes to transmit an image and then shut them down to conserve power. This can be accomplished by using the Ping Control and Time Control together. 1. Set the Time Control for the desired ON time and OFF time. In this case it’s ON at 6AM and OFF at 9PM 2. Set the Ping control to ping a non-existent IP address. 3. Set the Every(secs) to 180. This defines the ON Time for the relay. In this case we are setting to 180secs or 3 minutes. 4. Set the Fails = 1 and Wait(secs) = 0.

    5. On the System Configuration page set the Cycle Delay to 1800 this defines how long the Relay will be Off. In this case it’s 1800 secs or 30 minutes
