FAQs

Hello, how can we help?

    • How many amps can a HotDrop measure?

      Our standard HotDrop can measure up to 300 amps. We have additional offerings with our HotDropXL which can measure up to 5000 amps in various window sizes.

    • What is LoRaWAN?

      The LoRaWAN® specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.

    • What data does the HotDrop measure?

      The HotDrop captures three sine wave cycles of AC electricity –both 50 Hz and 60 Hz—sampling the waveform at a rate of 3.3 kHz. It then performs a root mean square (RMS) calculation to determine the magnitude of the current.

    • How close do the HotDrops need to be to the gateway?

      While LoRaWAN can transmit exceptionally far and penetrate through multiple layers of building materials LoRaWAN does have its limits. We have put together a table below showing different building materials and the db (link budget) or amount of energy it takes to penetrate through a typical building material. A typical LoRaWAN radio has a budget of about 150 db. For example, it takes about 2.8 db to penetrate through 3 inches of wood or about 27 db (~10x more energy) to penetrate through 3.5 inches of reinforced concrete. Radio signals have the most difficulty penetrating through metal. One of the items that impact the range HotDrop is the metal gauge of the service panel. The thicker the metal the smaller the HotDrop’s transmission range.

      Because every installation is different the type of building material between the HotDrop varies we try to be conservative in our range estimates. We typical see ranges of 1,000 ft feet in box retail store settings between the HotDrop and gateway. In a seismically reinforced hospital in California, we see a range of about 4 floors between the HotDrops and the gateway when the HotDrop is located 4 floors directly above the gateway. Also a rule of thumb, we recommend a gateway per building because building facades of often contain metal mesh or metal that limit radio transmissions.

    • Does it matter what direction I install the HotDrop?

      No, it doesn’t matter what direction you install the HotDrop. The HotDrop is self-polarizing. As long as you can close the latch on the HotDrop or the HotDropXL, you’re good to go.

    • What certification does the HotDrop maintain?
      • FCC Class B Part 15 compliance: FCC ID: 2APCG-VUHDC1
      • UL Certified (US & Canada): 508, 94, 746·        IEC – International Electrotechnical Commission
      • IEC 60695-11-10, -20 – Flammability Rating of enclosure plastics
      • NEC – United States National Electrical Code (NFPA 70-2017)
      • NEC 450.3B Compliant – Primary Side Protection
      • Canadian Electric Code: Part 1 Compliant
      • CE – Conformité Européenne: Declaration of Conformity
      • CE RED – Radio Equipment Directive
      • RoHS – Restriction of Hazardous Substances: Compliant – RoHS 2, verifying RoHS
      • WEEE – Waste from Electrical and Electronic Equip: Compliant – Category 9 Product

    • What security features does Vutility offer?

      The LoRaWAN protocol includes 128-bit AES encryption in the transport layer (from the device to the gateway). In addition to LoRaWAN’s transport layer encryption, Vutility encrypts all data at the device with a dual-cipher AES encryption. This becomes 128 to the 128th power of encryption – an extreme level. That is then encrypted in the LoRaWAN transport layer a 3rd time, resulting in an unprecedented encryption stance for IoT device. The dual-cipher encryption can only be decrypted by the Vutility servers. Vutility does not share the encryption keys at any time for any reason.

    • Is my data secure?

      Yes, the HotDrop uses a dual-cipher encryption to protect your data. The LoRaWAN protocol includes 128-bit AES encryption in the transport layer (from the device to the gateway). In addition to LoRaWAN’s transport layer encryption, Vutility encrypts all data at the device with a dual-cipher AES encryption. This becomes 128 to the 128th power of encryption – an extreme level. That is then encrypted in the LoRaWAN transport layer a 3rd time, resulting in an unprecedented encryption stance for IoT device.
