Our Technology


Wireless Mesh™ radios are used by H2O Degree (and many others) to communicate building control and monitored data using an open published communications protocol. The word "Wireless Mesh™" actually refers to an open radio protocol documented in the IEEE Standard 802.15.4. As such, any product that uses the Wireless Mesh™ protocol to communicate can send its data over any Wireless Mesh™ network. That's why Wireless Mesh™ is actively supported by 175 companies, including Motorola, Johnson Controls, Trane, Mitsubishi, Honeywell, Samsung, IBM, Itron Eaton, Invensys, Cisco, Hitachi and Texas Instruments, just to name a few.

Why Choose Wireless Mesh?

The Fact that Wireless Mesh™ is an open protocol may be the most compelling reason to choose a Wireless Mesh™ based system - but there are many other reasons:

  • Reliable Data Delivery

    Wireless Mesh™ radios form a self healing two-way mesh network that delivers much higher data through-put reliability. If one node fails, another picks up the load. If messages are not acknowledged, they retry. If interference becomes an issue, the frequency of the network can be changed. Wireless Mesh™ systems can run on any of 16 channels.

  • Device Control

    Every Wireless Mesh™ radio can receive as well send, so every meter can accept control instructions. For example, you can curtail utility use if the apartment is unoccupied or if the bill is not paid. Wireless Mesh™ gives you control capabilities no other radio network has.

  • Other Applications

    Wireless Mesh™ will lower the cost to add new Wireless Mesh™ based systems as they become available from any supplier, like security monitoring, smart temperature control, electric load controls on peak, time of use electric metering, intercom, text messaging to a display in each apartment. The list of possibilities is exhaustive.

Why Choose H2O Degree's Wireless Mesh™ System?

  • Power Agility

    H2O Degree goes beyond the Wireless Mesh™ protocol, by allowing transmit power levels to vary between 1 milliwatt (.001 watt) and 100mW (0.1 watt). H2O Degree adds a layer of software that allows each H2O Degree radio to adjust its power level up and down as the radio environment changes. So as furniture moves, new interference sources pop up, trees grow, and weather happens, transmit power is adjusted automatically to assure that data get through.

  • Long Battery Life

    H2O Degree uses replaceable industrial lithium batteries with a 5 to 7 year life. Better still, any H2O Degree node can be line powered, eliminating the need for batteries in many applications.

  • Easy Low-Cost Installation

    Our systems self configure. Battery nodes attach to the nearest line powered nodes. All line powered nodes act as mesh transceivers that form a robust mesh of redundant pathways. You can use any meter as a mesh transceiver by simply plugging it in, or tying it to a 24 volt source. For example, all H2O Degree Green Thermostats also act as mesh transceivers, as do all H2O Degree electric sub-meters. Or you can choose to line power one water meter in each apartment so it will act as a mesh transceiver. Dedicated mesh transceivers can also be used, typically mounted in the kitchen cabinet just over the refrigerator, plugged into the spare outlet behind the refrigerator.
