Frequently Asked Questions

  • 5. What extra features does iSocket 3G have?

    It can switch on/off or reboot any appliance with a plug remotely via a simple text message. It can do these operations by call as well – free of charge. This will also support precise temperature monitoring with an external temperature sensor, and it can work as a cellular thermostat. See some details in this article.
  • 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?

    iSocket 3G will only work on 3G (UMTS) and 2G (GSM) networks, but not on 4G (LTE) or 5G. We do not offer a 4G/5G model, because 1) right now the cost would be unreasonably high for the simple applications that iSocket 3G offers you - power outage and temperature monitoring; 2) traditional 4G networks are not tailored for such applications and 5G is not for them at all; 3) operators are not national-wide ready to deploy new standards, but they are good for marketing them, creating an illusion that you need to use these new standards. However, this doesn't mean that you can't use iSocket in your location. It is very unlikely that your area is only covered by the 4G network! In most cases if you have a 4G network, then you will also have 3G and maybe even 2G. That's why iSocket 3G will work in such locations. iSocket 3G also supports fallback to 2G networks. We believe that 3G networks will continue to exist for at least the next 7 years in most countries. Also remember, "G" stands for just "Generation" - it doesn't reflect the real standard behind. We will create a new iSocket model as soon as operators offer better technologies/standards that are specifically tailored for the Internet of Things (IoT) and Machine-to-Machine (M2M) applications - e.g. LTE CAT-M and NB1/NB2. But for 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.
