How does it work?

  • There is the Hub, AKA Router or Bridge, it manages the sensors within a certain range. The Hub connects to the Internet with WIFI/Ethernet.

  • The sensor connects to Hub via Wireless Mesh Network (ZigBee), which is more private and consumes much less power.

  • When the environmental conditions change, the Hub will receive the sensor data and upload it to the cloud.

  • Our devices are available under the most network environments globally.


How to pair the sensor with the hub?

  • For the sensors in the kit: Since the sensors in the kit were paired to the hub before shipping out from the factory. After the hub was bound to your MOCREO account, use a pin clip to poke the pin-hole for 1 sec, then release, then the sensor will wake up to pair with the hub.

  • For separately purchased sensors: You need to go through the adding process of the sensor via the App.

    • On the App, click the ‘+’ icon on the upper right.

    • Choose the corresponding image of the sensor, then go through the adding process.

  • Note: If the sensor is unbound from the hub, it also needs to perform the process of adding the sensor via the app.

What Should I do if the Hub Is Not Online?

  • Take the Hub closer to the router.

  • Check whether the router has a firewall policy to block ports 123, 80, 443 and 8883.

  • Unplug the power to restart the Hub.

  • Upgrade Hub firmware to the latest version, in Mocreo Sensor APP: [HOME]> [Hubs]> [Hub Settings]> [Check for Update].

  • Or Connect with a network cable.

  • If the hub still can’t be connected above method, please contact MOCREO Support (contact@mocreo.com).

What should I do if the sensor is offline or temp data not updated?

  • Check whether the Hub light is a purple breathing light. If it is not a purple breathing light, the Hub is not online. How to deal with if the Hub is not online? Please read What should I do if the Hub is not online.

  • use a pin clip pokes the pin-hole for one second, then release. Then blue indicator of the sensor will flash once, check whether there is a data update in the Mocereo APP; if there is no update, please contact MOCREO Support (contact@mocreo.com).

  • use a pin clip pokes the pin-hole for one second, then release. If the indicator light keeps flashing, please re-add this sensor in MOCREO App.

  • If the sensor data is still not updated through the above method, please contact MOCREO Support (contact@mocreo.com).

  • If the indicator light does not light up, the sensor is out of power. Please power the sensor first:

    • When charging, there will be a red indicator light on, and the red indicator light will go out after fully charged. Try the above steps again after the sensor is powered.

    • If the indicator light does not light up while charging, please contact MOCREO Support (contact@mocreo.com).

  • When you find that the sensor and hub are very close, the data is still often not updated, and the reason may be that the current hub environment has a large interference with the current hub channel (the default is channel 26). You can change the hub channel (Preferably channel 11) and re-pair the sensor to improve. The following is the guide on how to change the channel and pair the sensor:

How do I know which sensor card is the corresponding sensor?

  • Poke the pin hole of the sensor with the pin clip for 1 second, and then release it. After about 10 seconds, the background color of the coordinate sensor card on the app will flash once and change the color.

What should I do if the sensor temperature and humidity data are abnormal?

  • Check whether the sensor of abnormal data has been calibrated,[Home]>[Data detail]>[Sensor Setting]>[Callbration].

  • Put multiple sensors that have not been calibrated in the same environment to check whether the data is consistent. (The error does not exceed ±0.54°F (±0.3℃) and ±0.3%RH).

  • If the data is still different abnormally, please contact MOCREO Support (contact@mocreo.com).

What are the distances of the communication?

  • The distance between Hub and Sensor: For the indoor line-of-sight distance, it’s about 150ft (50m). In outdoor free space, it’s about 300ft (100m).

What is the maximum number of sensors each Hub could support?

  • One Hub only supports 16 devices, due to the memory constraints. And better to work with less than 16 connects to it directly. If there’s Zigbee router in between, that would be more stable.

How to switch the wifi connected to Hub?

You could go through the adding process of the hub again via the App to change the wifi that you want to connect to:
  • On the App, click the ‘+’ icon on the upper right

  • Choose hub, then go through the adding process:

    • Select ‘Connect to Wi-Fi’, select the new SSID that you want to connect to in Wi-Fi List, then input the wifi password.

After that, the hub will be connected to the new wifi.

Can multiple users monitor at the same time?

  • Yes. One MOCREO account can be accessed by multiple devices (phones, tablets) at the same time (Supports up 3 devices)

  • You can use a different phone to log into the same account, and all the sensors will be displayed on that device, which means multiple people can monitor Temperature and humidity on the same hub simultaneously.

Can push alert be set for multiple email addresses when Temp/Humidity is exceeded?

At present, the MOCREO Sensor App only supports entering one email address to receive alerts, but you can automatically forward emails from a specific subject or from to others by setting mail forwarding rules, so that multiple users’ mailboxes can receive alerts email from MOCREO<noreply@mocreo.com> at the same time.

Can the Unit be placed on a spot out of wifi range?

  • The unit is not suitable to work properly under such conditions. Here is why:

    • The sensor itself doesn’t have the ability to cache the data, but the hub does.

    • After the hub was taken to a place where there is no wifi, as long as the hub was in power, the hub can cache the data, when the hub was connected back to the wifi, then the cache data will be uploaded to the cloud altogether, here is a crucial point: once the hub was powered off, then the cache data will be cleared.

    • Once the hub was disconnected from wifi, the hub will reboot, and the cache will be cleared.

    • Hence it is suggested to place the hub under the wifi.

Does the hub need a a/c or d/c power supply? or is it powered by the ethernet connection?

  • We have provided Hub with a 5V / 1A power adapter and charging cable for free, which can fully meet your American power specifications.

  • In addition, our products are also suitable for POE power supply, but POE adapters need to be purchased separately.

How to maintain effective signal transmission between sensor and Hub?

  • In general, when there are obstacles indoors, we recommend the distance between sensor and hub 10M-15M [39.8ft-49.2ft] (different obstacles have different effects on the strength of the signal, users need to test a reasonable distance)

  • In addition, you should pay attention to: hub and sensor keep away from metal objects and surfaces; install the hub as high as possible; keep the antenna of the hub upright.

  • These practices are conducive to improving the signal transmission distance and stability between sensors and hubs.

How to verify the effective communication distance?

  • At the expected installation location(of the sensor), insert the Pin Clip into the pin-hole and press once shortly (less than 1second, then release).

  • You may see the corresponding card ( of the sensor) blinks on the MOCREO App, indicating that the connection between the sensor and the hub is good.

Why is it necessary to keep Bluetooth on when the hub connect WiFi?

  • The function of turning on the Bluetooth on the mobile phone is to help the hub to search the nearby WiFi hotspot list and select the WiFi hotspot you want to link.

  • When you successfully connect the hub to WiFi, you can turn off Bluetooth without keeping Bluetooth on.

  • In other words, you only need to turn on Bluetooth when you are performing a hub connection WiFi operation.

What’s the MAC and IP address of my IoT Hub?

  • Hub MAC address

    • You may find out on your router’s device information page.

    • Or, please find the S/N on the bottom of the device.

    • The MAC address for WiFi is the same as the SN, the MAC address for Ethernet is the SN + 3.

    • for example, C44F33383271, then, the MAC Address for WiFi is: C4:4F:33:38:32:71; The MAC Address for Ethernet: c4:4f:33:38:32:74.

  • Hub IP address

    • Hub’s IP address can be seen in the left navigation bar of app -> Hubs-> Hub Settings

What might be the possible reasons if the sensor failed to be added to the hub?

  • Please make sure that the hub firmware is the latest version.

  • Incorrect adding process. Please re-add the device according to the instruction on the App.

  • The distance is too far away from the hub. Please reduce the distance between the hub and sensor. Then try to add the sensor again.

  • There are too many sensors under this hub. (16 utmost).

What might be the reasons if the climate sensor often goes offline?

  • The distance is too far away from the hub. Please reduce the distance between the hub and sensor.

  • Running out of battery. Please replace it with a new battery.

  • The sensor is installed on a metal surface, and the signal was interfered. Please move the sensor to another place.

What might be the reasons if the hub failed to be set up to the WiFi?

  • Check if the WiFi password is entered correctly.

  • Check if the router has connected to the Internet.

  • Check whether the WiFi signal of the router is weak. Please move the hub closer to the router and try again.

  • Check whether the WiFi chosen is 5GHz WiFi. Please switch to 2.4GHz WiFi and try again. (since the MOCREO hub cannot support 5GHz WiFi)

  • If the troubleshooting above does work, please try to set the hub up through the Ethernet cable:

  • Connect the hub to your router through an Ethernet cable

  • Power up the hub

  • After the Hub is powered on and flashes the breathing light, press and hold the button on the top of the hub until the blue breathing light flashes to enter the “Setup Mode,” then click the “Continue” button on the App

  • Select the hub and click the “Connect” button to complete the configuration

    • Then log into Hub Web Portal.

    • Link Hub with an Account.

Precautions about the sensor when is placed inside a freezer

  • Avoid placing near the condenser. The water vapor of the freezer entering the internal circuit board of the sensor will affect the measurement accuracy of the sensor.

  • Avoid the adhesive from being frozen.


How to upgrade Hub firmware in LAN?

  • Background

    • Hub needs to download new firmware from SyncSign’s OTA server and update it. However, individual users may encounter network freezes during the update process and cause the update to fail. This method provides instructions for establishing an OTA server in LAN and then performing firmware upgrades.

  • Specific Action Steps

  1. Install a small Web server

  • Choose a PC running Windows OS in the same LAN as the Hub;

  • Download and install the HTTP File Server (HFS) software on the PC; The method of downloading the HFS software:

Visit the link: https://sourceforge.net/projects/hfs/files/latest/download (After jumping to this link, the link will automatically download the installation package).

  1. Run the OTA server in the LAN

  • Run the HFS software on PC
    • Confirm that the Web service is running on the same network segment IP address as the Hub: [Menu] -> [IP address]-> Select IP

(Assume the current IP address of the Hub is, thus please select
  • Import the latest OTA firmware of the Hub into HFS: [Menu] -> [Add files] -> latest.bin

  • Confirm that the URL of the firmware can be accessed in LAN, for example: may enter the URL on another PC or smart phone in LAN via browser to confirm)

  1. Perform the upgrade

  • Provide the MOCREO Support (contact@mocreo.com) with: A) Hub’s SN; B) The available firmware URL(Verified in the steps above).

  • Finally, the MOCREO Support will try to upgrade the Hub (Note: the PC where HFS is installed needs to be turned on and running the server, the Hub needs to be kept online).


Does the sensor charge or replace the battery?

  • The sensor is rechargeable.

  • 1 Year Standby.

How do I know if the battery is used up?

  • You can find the battery level on the sensor card on the app.

Data & Cloud

What is the method to store data? Is it sending data through your server in China?

  • The web service is hosted on AWS (US).

How often will the App refresh the data collected by the sensor?

  • The sensor measures temperature and humidity every 3 seconds. If the temperature change between two adjacent measurements exceeds 0.5 ° C or the Humidity change exceeds 6%, so long as one of these conditions is met, the current temperature and humidity data will be uploaded to the MOCREO cloud immediately and refresh on the App.

  • If the temperature and humidity do not exceed the ranges specified in #1, data will be uploaded to the MOCREO cloud every 10 minutes.

Zigbee Protocol

Is this an 802.11 device or an 802.15.4 device, or both? If it’s 802.15.4, which protocol are you using?

  • The Hub is using both 802.11 and 802.15.4.


Do the push and email notifications require any ports to be opened on the local network firewall?

  • The hub must be able to access the Internet. The firewall should allow outbound to visit targeting ports 123, 80, 443, and 8883.

  • No inbound ports or NAT reversals are necessary to setup.

  • Open http://test.anypi.com:8883 on any browser, if you see a “OK”, then there is no problem with the firewall’s 8883 port.
