Smart Street Lighting: 25 Things You Need to to Know
No, for the following reasons:
- A luminaire is a fixed asset and it will never move during it useful lifetime. At installation, the geographical position of each luminaire is automatically set so there is no use for a GPS module afterward. Claims that it will help you keep track of any thefts are just misleading since the GPS will have lost its power to track and transmit and may not even be in RF range if ever reconnected…
- Claims about auto-commissioning should be re-evaluated, we believe that the correct installation method is to scan the node and perform a complet test set while up in the bucket truck and have the confirmation that everything is fully functional and that the installer won’t have to return to fix a miswired or defective installation.
- A GPS module is an extra cost for any project size (physical cost and energy consumption). It is also a component subject to failure
- Having to wait for the GPS to acquire its coordinates once powered up is time consuming.
- The GPS modules add continues power consumption to the module 24/7
Even after reading the above facts, if you still prefer to have a module with GPS, we offer the option – simply specify it when you place your order.
It depends on the selected radio technology. Some nodes communicate directly to a communication tower while others communicate to a local gateway.
For Data logging & scheduling, we use a secured protocol developed by Dimonoff and encrypted at 128 and 256-bits AES, above standard protocols (IEEE 802.15.4, radio frequency 2.4GHz or 900MHz). Back-end (Gateway to Server) communication can either be Ethernet or Cellular.
Yes, it is possible that the pole on which the gateway is installed will get hit by a truck.
This is the reason why the Dimonoff system has multiple levels of fail-safe and fallback functions that will keep your system operational while a crew goes on site and repairs or replaces the gateway. Also if desired, all nodes from an adjacent zone can be transferred to a neighbour gateway in a matter of seconds and returned once the issue is fixed.
Yes, our system universally works with any type of fixture from any manufacturer.
Please make sure to specify 0-10 V or DALI controllable drivers (for dimming purposes) and ANSI C136-41 or Zhaga Book 18 socket option from your fixture supplier(s) for RME modules twist-lock installation or RTM for inside fixture installation. Dimonoff has OEM agreements in place with most of the major fixture manufacturers.
The RME is also compatible with ANSI C136.41 5-pin and ANSI C136.10 3-pin standard receptacles with no light level control.
No, our relays (nodes) have everything included in a single module.
The MTBF was calculated according to Telcordia SR-332 to be:
TEMP = 25°C
- FR(90) = 201.88724 FITS
- MTBF = 4 953 260 HOURS (565 years)
- Durée de vie= 175 200 HOURS (20 years)
- Indisponibilité (Q) = 0.03988437 (chance of a failure within 20 years = 3.98%)
TEMP = 40°C
- FR(90) = 280.41113 FITS
- MTBF = 3 566 192 HOURS
- Lifetime = 175 200 HOURS
- Unavailability (Q) = 0.058319226 (chance of a failure within 20 years = 5.83%)
We offer several options depending on the radio network supplier that you prefer, such as Mesh, LoRa and cellular.
The mesh radio communication topology used is based on a principle where messages are repeated from one radio to the next until a certain time limit or a certain amount of repetition (also called hops) is reached. The mesh approach we use is called flooding, where each and every radio receives and re-transmits each communication until the time or repetitions limit are reached. This method was originally developed by DARPA for the US Army to ensure very high reliability. As a comparison, Zigbee use a routing type where a route needs to be established by a coordinator and each message follows a specific route with no redundancy.
The end-user has the options to host the main database of the system either on its own servers or on the cloud or elect for a SAAS type service.
Central Management Server runs the Dimonoff | SCMS software platform that is typically licensed to the client, and runs on the client’s server. It can also easily be hosted on the cloud, whether by the client renting CPU & disk space at an infrastructure service provider, or directly by Dimonoff. Software applications and database will be installed and will execute on the chosen server. Client access is provided using Dimonoff client software or through a web-based application. The Central Management Server is primarily used for data acquisition synchronized with gateways, configuration & modification, reporting, and as the Web server for Mobile Access and Control (smartphones, tablets, etc…).
Our integrated metering is utility grades (which means +/- 0.5% accuracy or better). Each device is individually calibrated in-plant, during QC process.
Yes, Dimonoff can also present the entire system by allowing access and in real time to a large-scale project that has been installed recently, this is an experience you don’t want to miss. Interviews with managers of already deployed projects can also be organized.
Industry standard 0-10V and DALI, both source and sink

- 10 programmable levels with delayed timing and advanced scheduling and trimming.
- Additional control parameters for Min-Max dimming
- Min. Lamp burn time before dimming (to respect the manufacturer warranty)
- Min. Dimming Level (%), Min Percent Level (%) and Max Percent Level (%)
- Low Power Mode (%) (Demand/Response)
- Turn Off below Min. Dimming Level options
- User-programmable transition time: from 0% to 100% in x sec. (max: 65535 sec.)
We offer both models in order to answer your requirements and fixtures specifications:
- Internal: The small footprint of our RTM module makes it easy to find a location inside the fixture enclosure, this is especially well suited for decorative style.
- External: RME, using a NEMA C136.41 standard 5 and 7 terminal twist-lock receptacle for both electrical and dimming control signal connectivity or the internal model may be installed in a NEMA 4X box and mounted remotely.
The external C136.41 module is 100% compatible with the old C136.10 3 prong photocell sockets, this means that the installation process is the same as when you had to replace a damaged photocell.
In addition, in order to geolocate the fixture, the node barcode needs to be scanned at installation time using user-friendly tools offered by Dimonoff.
All the above names are the same and follow the same purpose: in reference to IES TM-23-11: a device designed for interfacing between two communication networks that use different protocols, such as BACnet to DALI, or DMX512 to 0-10VDC.
A gateway may contain devices such as protocol translators, impedance matching devices, rate converters, fault isolators, or signal translators as necessary to provide system interoperability. For the purposes of this document, refers specifically to a device that (at a minimum) serves as the interface between one or more Field Devices and a Central Management System, typically translating from a wireless Field Device protocol to a standardized Wide Area Network (WAN) protocol, such as WiFi (i.e. IEEE 802.11xx), Ethernet (i.e. IEEE 802.3), or LTE Cellular (i.e. 3GPP Release 8)
All the above names are the same and follow the same purpose: according to IES TM-23-11: the device that originates a command to execute a lighting change.
Most commonly associated with a lighting control station or control console, a controller may also be a sensor or other automatic device operating without human interaction. For the purposes of this document, refers specifically to a device that physically monitors and controls Luminaires installed at Control Points, reacts and responds to logical and physical inputs, makes control decisions using internal algorithmic and logic functions, and communicates via a network protocol.

- All data transmitted over the air link is encrypted with various encryption methods.
- IEEE 802.15.4 Secured meshed-network (128-bit and 256-bit encryption). All user data transmitted over the air link is encrypted with various encryption methods.
- IP addresses (destination or source) are never transmitted “in the clear” (non-encrypted) over the air link, reducing the risk of attacks on both mobile and servers.
- TCP/IP packets are not transmitted as a whole.
- Last, Dimonoff uses its own command-set protocol, built with security in mind. Each node is uniquely serialized – Additional security dynamically builds itself when defining Groups & Scenarios.
It depends on the radio network selected.
As an example, for DIGI: 2.4Ghz and 900 Mhz, up to 1000 nodes. Dimonoff recommend an average Gateway ratio of 500 to ensure rapid data collection (of all nodes) and for future growth of the system.
Each node has built in “Demand Response” load-shedding functions with up to 10 levels of priority.
