Frequently Asked Questions (FAQ)
Is my meter compatible with Coronis radio modules?

To be sure if your electric, gas or water meter is compatible with Wavenis radio modules, there is a validation phase. However, you can begin by checking the following:

  • The contact type (dry or electric)
  • The pulse duration (close contact) must be 32ms minimum
  • The pulse form: during less than 100µs, the voltage must be 2,7V
  • The impedance must be 100ohms with the close contact and higher than 20Mohms with the open contact

What is RSSI?

RSSI stands for Received Signal Strength Indicator, a measurement of the power present in a received radio signal. RSSI directly represents the quality of communications between two wireless modules.
The maximum value (RSSI_Max) depends on the vendor. In Wavenis technology, RSSI_Max = 32. We consider this value as 100% RSSI. In order to ensure the highest possible Quality of Service (QoS), this percentage is taken into account when building a network. For example, the minimum acceptable RSSI level in a crowded area is around 20%.

How do I change the configuration of my modules?

Every Coronis Wavenis wireless module contains internal parameters that you may modify. These parameters may be set identically for all your modules or specifically for individual modules. Parameters are accessible and configurable wirelessly.
Customers generally connected to end-modules using one of the Waveport (USB or RS-232) modems, either via a PC or handheld computer. Parameters include:

    Coronis services
  • Data logging mode selection and activation
  • Input selection
  • Pulse weight
  • Communication mode
  • Alarm management
  • Index management
  • Wake-up management
  • Time and date
  • Leakage thresholds

Please refer to each product's user guide for more details on these parameters.

How do I change the batteries in my Waveflow?

In most cases, Coronis products are delivered with a IP68 protection level. They are therefore "potted" with silicon gel to support continuous immersion in water, water-tightness and impermeability against dust. You may not change the battery in a potted module.

How long do batteries last in Coronis' Wavenis products?

Battery life in any wireless product depends on your usage. Wavenis was specifically designed to provide long-range and ultra-low-power wireless connectivity to enable customers to deploy products in the field and leave them unattended without having to worry about the cost or hassle of changing batteries on a frequent basis.
Energy efficiency depends on module activity.
This includes "expected" module access, such as for transmitting sensor readings, as well as network configuration and topology. In fact, by optimizing your wireless mesh network topology, you can significantly improve the battery life in individual modules. For example, with Wavenis you can reduce the effect of "over-hearing", which causes modules to exit their battery-saving sleep mode unnecessarily. Battery life also depends on how frequently you query end-point modules or how frequently they transmit their data automatically.
Generally speaking if you respect the following conditions, you modules can perform reliably on a single battery for 10 or more years

  • Relatively few transmissions a month (the opposite of a broadband Internet connection!)
  • Small amounts data (which is the case in most M2M applications)
  • Follow Coronis' network advice

How does Datalogging work?

Data logging refers to when a wireless end-point, such as the Coronis Waveflow or Wavesense products, records some type of measurement from a sensor device or utility meter. These devices are generally wired to the wireless end-point or platform, either by integrated circuit or cable. Some sensors transmit electronic pulses that can be counted by the end-point, while others transmit actual index values. This information is then stored in memory on the wireless end-point module, and transmitted to mobile readers or over a fixed heterogeneous network.
For example, index data logging in Coronis Wavenis-based products is programmable, with the following frequencies:

  • Time steps
  • Once a week
  • Once a month

You can save battery power by storing sensor data (up to 24 index readings on a standard module) and transmitting it in a single operation. This reduces network communication and extends battery life both in the module and throughout the network.

Can I use your Wavenet Manager software with Wavetherm devices?

Yes, Wavenet Manager can be used for telemetry applications (Wavetherm, Wavelog, Wavesense) as well as smart utility metering. You must specify the intended application when ordering Wavenet Manager.

Note: when using Wavenet Manager to read mixed networks contains both telemetry and metering end-points, you must run separate read operations on each type of device.
