NodOn STPH-4-1-00: Zigbee Temperature and Humidity Sensor with Solar Panel

Having a smart home with Zigbee technology and no battery maintenance is starting to become a reality with NodOn’s STPH-4-1-00 temperature and humidity sensor, powered by a solar panel.

Why does NodOn STPH-4-1-00 have this price?

NodOn is committed to designing quality devices and STPH-4-1-00 is an innovative sensor as it incorporates Zigbee technology and works with a solar panel, making it unique in the market.

Advantages and Disadvantages of the STPH-4-1-00 sensor

NodOn STPH-4-1-00 sensor usage tutorial

Let’s discover the details of this NodOn STPH-4-1-00 sensor.

Technical features of NodOn STPH-4-1-00

If we open the packaging, we can see that the instructions are directly indicated on it.

And of course, we have this temperature and humidity sensor from NodOn that works with a photovoltaic cell that recovers energy from ambient light.

It is the method called Energy Harvesting, i.e. to recover ambient energy and NodOn already had this philosophy of not using batteries with products using EnOcean technology and now they are pioneering to offer devices with ambient energy recovery with Zigbee technology.

According to the French company NodOn, once this device has a recharged battery, it can operate in total darkness for 5 days.

And if you have it in dark conditions for a long period of time, in this case, you can also use a CR2032 battery backup which is not included, being another practical detail for this sensor to continue measuring temperatures and humidity levels in these contexts and the manufacturer indicates a battery life of up to 3 years.

This sensor communicates its information thanks to Zigbee technology, which is an excellent compromise for a unified smart home, with low power consumption and secure communications.

In addition, the maximum direct range of this device is 30 m to communicate with the home automation hub.

And another advantage of Zigbee technology is that it automatically creates a mesh network between devices if you have some of them connected to the power supply, such as sockets, light bulbs, modules and more.

So the range of this sensor can be improved in your home if you use additional Zigbee devices connected to the power supply.

This device measures temperatures from -5°C to +45°C with a resolution of 0.5°C.

And it should be noted that it must be used indoors as it has an IP20 protection rating and a temperature of use from 0 to +40°C.

Regarding humidity, it measures levels from 0 to 100% RH.

It weighs 30 grams and its dimensions of 85x34x15 mm are larger than other temperature and humidity sensors, but this is justified by the size of the solar panel which is necessary for the proper functioning of the device.

And although its price is much higher than Zigbee temperature and humidity sensors from other brands, in this case, we will not need battery maintenance.

It should be noted that NodOn designs quality products and companies such as Leroy Merlin and Schneider Electric have adopted some of these white label products to offer them in their catalogues.

How to link the NodOn sensor STPH-4-1-00

As a Zigbee device, you will need a compatible Zigbee hub.

The interesting thing about NodOn is that it shows its interest in making its devices perfectly compatible with different popular home automation solutions on the market and this sensor is compatible with Jeedom, Home Assistant with ZHA and Zigbee2Mqtt.

NodOn also indicates compatibilities with Alexa, Tuya, Domoticz, Edalso, Energeasy Connect and SmartThings although in some cases, due to manufacturer limitations, it is possible that only the temperature will be reported so I recommend that you check these compatibilities in detail before your purchase.

In the user’s case, he has the Jeedom Luna home automation hub and the Zigbee2Mqtt platform, which you can also use with Home Assistant.

You must activate the inclusion mode of your home automation hub.

You have to open the back cover with a screwdriver by pressing on one side and pushing the cover upwards.

Now, you must turn ON your sensor from its physical button inside.

And you must press the physical association button once.

At this point, the sensor should appear in the interface of your home automation hub.

So now, you will be able to read the temperature and humidity measurements from the sensor from the interface of your home automation hub.

How to install the temperature and humidity sensor STPH-4-1-00

To install this NodOn sensor, simply choose a strategic area in your home where you want to monitor the temperature and humidity level and fix it with a double-sided adhesive tape that is included or with 2 screws that are NOT included.

Of course, you should not install it near a window.

Or a radiator.

Nor should you expose it to direct light to avoid false measurements.

You can simply install it on a wall or on a piece of furniture where there is good exposure to light and it is recommended to place it 1.2 m above the floor to have representative temperature measurements.

In addition, we can enjoy OTA updates, Over-The-Air, so that our device has the latest improvements over time.

Detailed functions of NodOn STPH-4-1-00

In Zigbee2mqtt, we can see different information about this device. “Battery” is the battery status in percentage from 0 to 100%.

“Temperature” is the temperature measured in real time.

And of course, you can also have a temperature history over time.

“Humidity” is the humidity level measured in real time.

And you will also be able to follow this level with a track record.

This sensor will send temperature and humidity measurements every 100 seconds whenever there is a variation of 0.5°C or a variation of +/- 2% humidity.

It will also send automatic reports every hour or according to your personal settings, even if there is no change in temperature and humidity, to indicate that the device is still working.

And “Link Quality” is the quality of the Zigbee link, i.e. the quality of the communications between your Zigbee sensor and your home automation hub, and we have seen in other content how to analyse and improve this Zigbee range.

Automations with this Zigbee temperature and humidity sensor

If temperature and humidity sensors are so popular in smart home projects, it is because of benefits such as being able to adjust heating according to temperature measurements in areas of your home.

But there are also other use cases such as being alerted if measurements are too low or too high in areas such as warehouses.

And the humidity level can also be of interest, both to receive alerts in case of low or high humidity and to adjust the ventilation.

One last very interesting example is at a professional level, having this type of sensors in buildings and any other environment avoids battery maintenance every X months, so it represents a time saving.

In the case of the user who already has a Jeedom Luna home automation hub with Zigbee2Mqtt, he uses this temperature and humidity sensor in an area where food and beverages are stored.

In short, having devices with solar panels and Zigbee technology is a very interesting proposition and we hope to have more and more different product profiles with this combination.
