Technical specifications

Description: M Climate Wireless Thermostat is a stand-alone thermostat entirely by solar energy using an organic solar panel. The device features a 2.9″ e-ink screen, sensor for movement (PIR), temperature and humidity sensor, LUX sensor and 3 buttons. The user can change the target temperature and see current indoor conditions. The device sends an uplink after any event as well as periodically. The data from the Wireless Thermostat can be used in any Lora WAN-compatible system, incl. Building Management Systems to control different appliances in the building. Created by M Climate™

Placement guidelines

Do not place the device in direct sunlight, as this will result in gradual worsening of the performance of the solar panel. A few hours a day in direct sunlight wouldn’t be an issue.

Display’s content

The image below has all visible elements of the display activated.

The 2.9” e-ink display supports fast partial refresh. Full refresh is performed every 12 hours (period can be adjusted via a downlink) to avoid the e-ink phenomena “image sticking” and steer clear of permanent damage to the display

Behavior

Start-up behavior
The device starts when you expose it to light or press the Reset button on the back. At startup, the device measures the voltage of the supercapacitor, which is storing the energy harvested by the solar panel. If the voltage is within the working range of the device, the device will initiate a Lora WAN

Collecting and storing energy

The energy harvested by the Organic Solar Panel is stored in a supercapacitor. If the supercapacitor is discharged for some reason, the device will wake-up again when it has harvested enough power so that the voltage of the supercapacitor is within the working voltage of the device.

Example reasons for preliminary discharge can be:

Device installed, but not provisioned in a Lora WAN Network Server.
Gateway not present.
The device has been stored in packaging for too long.

If you want to get started quickly, you can use the USB-C port to charge the capacitor from a 5VDC power supply, which takes approx 20 minutes.

The time it takes to recharge will depend on the lighting conditions, but in a brightly lit office with 1000 lux, it should take around 12 hours.

Using multiple energy

The Wireless Thermostat has three options for power supply:

Organic Solar Panel
USB-C
2 or 4 AA Batteries (1.5VDC each)

You can use both solar and USB-C or AA batteries at the same time. If you use USB-C or AA batteries, the super capacitor will be charged and the solar harvesting will always be with highest priority.

Data transmissions

Once joined, the device will execute two types of transmissions:

Periodic, as configured
Immediate, when something changed – e.g. target temperature changed or movement detected in the room.

All transmissions are subject to complying with the duty-cycle limitations of LoRaWAN end-devices.

Installation

We recommend installing the device in an open environment (e.g. not in a recess) at 1.5m height. Do not install the device near big metal items as it will worsen the RF performance. Use double-sided tape to attach it to the surface or screws and dowels to attach the anti-theft bracket in a more permanent manner.

Once you’ve attached the anti-theft bracket, place the device on top so the two mounting points on the bracket correspond with the device’s plastic. Slide down and secure with the security bolt on the bottom.

If you decide to insert AA 1.5VDC batteries into the device, you can use either 2 or 4 batteries.
We recommend using Energizer Ultimate Lithium AA L91. You can insert 4 batteries as shown on the device’s plastic or 2 batteries as shown in the picture below.

When using 2 or 4 AA batteries, please make sure that all batteries are new. If one of the batteries has lower voltage, it’s not possible to use the full energy capacitance. That challenge is valid for all devices operated by multiple battery cells, e.g. your TV remote.
Installation

Commissioning

Before you install the device, we highly recommend that you first commission it on your LNS. Once the device is restarted or exposed to light, it’ll initiate a Lora WAN Join Procedure using SF9. Please, make sure you enable ADR in your LNS and/or mark the device as static. The lower the spreading factor, the better the performance of the energy storage will be.
