With builtin WiFi and USB Host Features, it is easy to download data or update software whether your home has dedicated internet or no internet at all.
The display communicates with other GR4 modules over a network cable and can also draw power from the network to charge itself. The display can also power the bus in order to communicate with devices that do not have power. Data from external modules are gathered onto the logger itself and relayed to the internet of things via the display's WiFi.
Display features include:
- 3.5" Colour Touch LCD to display information about the system
- WiFi to communicate with the IoT (internet of things)
- Memory enough to store 6 months worth of data
- Micro logger with 6 inputs (4 Analog, 2 Digital)
- USB Host to export data in Excell format directly to FLASH Drive
- Battery enough to power the logger and display for 12 hours
The WiFi connection is safe to use on a mobile hot spot as it uses very little data.

We offer a standard in-line type 20Amp sensor for most projects, but other capacity sensors are also available. We use a generic 3.3Volt allegro hall effect sensor (ACS725LLCTR-30AB-T) commonly found inside Arduino modules. Efergy split core CT's are also available, although they are too large for most installations.
Sensors are probed continously and a true RMS value calculated and averaged over the 5min interval until the measurement is timestamed and saved onto FLASH memory.
The Logger can also take two pulse inputs, which can be connected to water or power meters that support pulse output. Most elster water meters and elster power meters give out pulses when a set unit of measure is counted (optional probes may be required from the meter manufacturer).
The Logger can also communicate with external devices over a High speed RS485 network to expand capabilities. The Logger can communicate with the GR4 Smart and the Inverter in this manner.
Data can be exported to Excell CVS files to visualize your data on any spreadsheet editor.
