Frequently Asked Questions

  • 6. What's the difference between short and long temperature sensors?

    Long sensor is for the temperature measurement at some distance from the unit or in a harsh environment, such as salt water of fish tanks. The short one is just for the ambient temperature.
  • 7. I’m keen to know more about the temperature monitoring features of iSocket 3G

    Please check this post and user manual.
  • 8. We already have a 4G network and 5G is coming. Will iSocket work on these networks?

    Note, "G" stands for "Generation" - it doesn't tell about network standards. iSocket 3G will only work on UMTS (well, 3G) and GSM (2G) networks. Traditional LTE (4G) networks that you use for your phone are not tailored for such simple applications that iSocket offers you - power outage and temperature monitoring. Mobile operators (carriers) all over the world agreed to create new technologies for the Internet of Things (IoT) and Machine-to-Machine (M2M) applications, so for devices like iSocket. These standards called LTE CAT-M, NB1, NB2 and they belong to next *G*enerations. We will create a new iSocket model for these standards as soon as operators will be ready to deploy them national-wide in your country. At the moment, operators are only good on marketing, creating an illusion that they are ready and you need to use these new standards. It's not true. If you want 5G device now you have to pay $300+ for a very raw product and it will work in just few places in your country. Forget about 5G for now, let's see after 5 years. We believe that UMTS networks will continue exist for at least the next 6 years in most countries. If you have traditional LTE (4G) in your area it does NOT mean that you don't have UMTS. Right now, iSocket 3G is the best way to solve your power or temperature monitoring problems. See this article about the situation in the mobile world.
  • 9. Will iSocket text in the event of a power blink / flicker / glitch / surge, not necessarily an outage for several seconds / minutes?

    iSocket can detect flickers/glitches (by fact, outages) of at least 100ms duration when the setting PFAILDELAY is set to "0" (it is set to 1 second from the factory). Of course, different factors should be taken into consideration, such as capacitance, length of wires, etc. It is important to understand what exactly means the outage for iSocket. The outage is a drop of the mains power (input power provided to iSocket) below ~90 VAC for ~100ms, while your equipment will be, and most probably must be, connected to the mains separately from iSocket. When you consider using any external glitches detection device which is not a part of the monitored equipment itself, you should understand that regardless of parameters of glitches/flickers an outage for a one equipment not necessarily will be the same for another. Generally, no one external device can guarantee 100% correct detection of glitches for another device, because characteristics of two devices connected to the mains separately will be different. You will either have false alarms or no alarms from time to time. Only a built-in facility of the monitored equipment itself can be considered as 100% guarantee if your concern are glitches. The recommended option if your concern are power glitches will be to use a small UPS or even a surge protector for your equipment so that it can survive short outages and keep iSocket for notifications about longer outages as there will be no any external device that can help you to detect such short outages. Worth mentioning, if you don’t receive a power glitch alarm with the setting PFAILDELAY=0 then your equipment really needs some frontend protection first - a protection that allows you to delay the outage.
  • 10. Can I monitor -80C (cryostats) with my iSocket?

    You cannot go below -55C with iSocket temperature digital sensors, however you can monitor power interruptions to your cryostat and so you know that something bad happened. You do this outage monitoring by installing iSocket to any free wall socket that is on the same electrical circuit with your cryostat. For monitoring low temperatures inside cryostats you need PTC sensors and proper components cascade that can support such sensor, because such sensor is basically just a resistor. We use digital Maxim Dallas sensor and iSocket will only read that sensor directly. The lowest temperature of the sensors is -55C.
  • 11. Do I need to plug my appliance into iSocket in order to receive power outages alerts?

    In order to detect power failures to your appliances (like fridges, pumps, etc.) it is enough that you plug your iSocket to any free wall socket as long as this socket located on the same electrical circuit (powered from the same breaker) with your appliance. You do NOT need to plug your appliance into iSocket, because iSocket detects mains failure - power interruptions in your wall socket. If you do plug your appliance into iSocket you need to text message "ON" to energize your equipment connected to iSocket, because internal relay of iSocket is switched off by default.

    NOTE! Connecting your appliance to iSocket without real needs you create a so called extra point of failure. For example, occasionally you can text "OFF" and de-energize your appliance or you can forget to text "ON", or you can mess up with thermostat settings and the the relay turned off, or iSocket's internal relay will fail and your appliance will be de-energized. Note about relays: they are designed for resistive loads, not for inductive. Some fridges/freezers with pumps will have surges on power on/off events and there will be inductive load that may damage relays. It is not failure of your fridge, neither iSocket. This is how fridges/freezers designed and how relays are designed too. We do NOT recommend to plug fridges/freezers into iSocket directly without real needs.

    What is the "real needs" then? Well, say, you don't have any free wall socket for iSocket on the same electrical circuit that your appliance. If you are going to plug your fridge to iSocket keep in mind that reminder about relays. Another reason why you may want to plug your appliance to iSocket is because you want to switch it on/off/reboot remotely (say, you have a router). This is absolutely fine as these are features of iSocket: remote switch on, remote switch off, remote reboot. So the main reason when your appliance should be connected to iSocket is when you plan to use these features.
