Helium

For the light hotspots, all the supplier is waiting for the new SDK released by HNT. As a result, you can’t find any supplier who could sell hotspots for you now. However, in the case of the same function, our price policy is to keep the same price for full and light. You can try our full hotspots first.

 

Rockchip’s 3328, performance is enough for HNT.

We don’t have a TTL interface, but we can provide SSH.

Our light hotspot device will be available in July. At present, there is no company on the market that has been certified by Helium.

At present, we do not modify the plan, we only focus on providing high-quality equipment.

Gateway

Yes, you can get the sdk from github (https://github.com/dusuniot/Dusun_Gateway_API). As for other documents for development, you can refer to www.dusuniot.com/developer-zone.

We had a BLE communication program and the use of Dusun Gateway API as samples on Github. Please refer to www.dusuniot.com/developer-zone for the further information.

Yes, you can use Tuya app or our own app called roombanker for testing.

You should offer relevant information on the general quantity and then we will communicate with TuYa about this requirement.

Yes, if you only need to use the Tuya devices.

Currently, we don’t have this kind of app. However, you can configure the gateway through our website.

 

We don’t make UBoot public generally to avoid potential issues and we modify it by ourselves in most cases.

Yes, the maximum RAM is 128MB and that for Flash is 16MB.

yes, we have developed firmware and own source code.

The stack is Linux Openwrt based.

HTTP/MQTT is basically supported. LWM2M or COAP can also be used. In fact, Eclipse open source Mosquitto(MQTT) and Wakaama(LWM2M) are tested on it.

The Hub can be programmed with C/C++/Python. Due to the limited hardware resources(RAM:128M ROM:64M), C/C++ is recommended.

ZigBee, Zwave and BLE are supported. We provide simple code samples to show how to communicate with IoT devices.

Yes. MQTT, COAP, and LWM2M protocols are tested on it. Eclipse open source Mosquitto(MQTT), Wakaama, and californium are tested on it. We use Mosquitto for our platform communication.

Yes, we provide samples for ZigBee/Z-Wave development and a BlueZ code sample for connecting BLE devices.

No, we do not support Lora now.

Yes, we will support NB in the future and have developed an NB lock.

We support many carriers. AT&T, China Mobile, Japan KDDI, Korea LGU+, and UK EE are tested.

The gateway is embedded hardware which is resource-constrained, So only C/C++/python are supported (C/C++ is recommended).

If that brand’s device supports standard Zigbee devices, we can establish stable communication.

Currently, we don’t have this kind of app, you can use the website version to configure the gateway.

We used standard ZigBee 3.0 protocol, that is to say, if they support it, we can communicate with their gateway.

By default, we have a sample that used the MQTT communication protocol to upload data to the server. As for the method to upload data to the cloud server, we have API for Azure now. If you want to communicate with another cloud, it requires further development of API.

Connect to Dusun gateway 0177 and flash the firmware.

Yes, you can send a JSON format command to the device to get the status. In general, the bulb would report its status by a certain time gap.

Yes, we had this function to reconnect to the router automatically.

Our gateway can establish up to 100 connections during our test.

You can pair it with the button directly as long as it is Zigbee 3.0 protocol.

As for cloud service, we’ve developed API for Azure. If you want to use the AWS, you could rent their cloud. At the same time, we can help do this with some fee for the integration.

 

You can configure it in the programon the gateway to store the data received for a certain time gap when the power supply is down.

You should develop your own cloud platform along with your own app to obtain the data from the ZigBee sensors.

 

It can be done by replacing our current Zigbee module with the 868Hz chipset.

We dock with Azure, Aliyun, and Tuya. However, we don’t offer cloud services, the customers should be able to integrate our gateways with their own platforms.

The Audible and Visual Alarm need a socket for the power supply. As for now, this alarm can just work as an endpoint device rather than a repeater.

Our gateway is programmable and you can login our gateway to develop your own application. We can release you to the program environment. The SDK, Toolchain, and API reference can be released to you by FTP after the NDA sign and sample order are placed. If you connect the gateway with a beacon, the gateway can send data to your own cloud or app. You can use your cloud or app to control the device, so as to have 2-way interaction.

If the quantity is big, the task can be inserted and the price is 10usd+.

Sorry, we don’t make audible alarm products or visual alarms. If you need, we can help you purchase those products in China when we establish the official cooperation.

We have both options for your selection: BG96(LTE Cat M1&Cat NB1&EGPRS module); EG91(LTE Cat1)

we have already integrated the blood pressure (SIG BLE profile) working with our gateway. Plus, we can release you MQTT API for quick integration with your server.

Our LTE gateway can be connected to worldwide carrier networks. Our customers in the USA have already used our gateway connecting to AT&T networks.

Please see this post for further information.

 

Yes, you can develop the application based on our gateway and use the python script. Please refer to this page.

then he will know how to develop the application base on our gateway

You need to replace the phone connecting to  gateway connecting. Normally we provide gateway SDK/Toolchain/device API program reference documents to customers, so they can integrate their own device into the Cloud/Service through our gateway. If your engineer can reprogram the gateway by C or C++ or Python, we would like to provide these documents. If you have nobody to do this, our engineer can do it for you with an NRE fee.

Yes, the gateway will come with a Luci configuration webpage where you can configure the gateway and beacons.

Yes, we can support MQTT over SSL, and MQTT to port 8883.

Yes, we support AP and client mode concurrently.

Gateway tech issue

The gateway’s app can be opened by pressing the button on it for 4-8s or pressing it one time. Then you can connect to this WiFi using pc with a password last 8 bits of the mac address of the gateway, then log in with 192.168.66.1

 

Sensor

Currently, we use the gateway to communicate with Amazon rather than the sensor itself. WiFi devices can do this, but most of our sensors use the ZigBee protocol.

Our gateway is based on the OpenWrt system, which uses Linux Kernel. We do not support Android on the hub.

Yes, it can communicate with the cloud server with any protocol you like, by default we use MQTT broker for communication. The ZigBee hub runs the OpenWrt system as well.

 

Yes, we have a water leak sensor, when the two pins of the sensor are connected, it will give an alarm.

Currently, we don’t have it, our sensor can detect from -5 to 65 degrees.

Once the water is enough for the two pins of the water detector to be connected, an alarm will be triggered.

We don’t have it now, but we can design it for you if you order more than 2000 pcs.

The bulb itself would report and upload information for a certain time gap. If you want to get the status of the sensor, you can call the function rbsdk_get_attr. There is no accomplished solution from the MQTT server currently.

You can send a certain command to the device and see what the report is.

As for the smart outlet, we’re sure it has the ability to monitor power consumption. You can view the uploaded data. The device should upload data other than switch status.

If you still have any doubts, please send us the message you received from the socket so we can point out which part of it is the power consumption.

Sure, the relay can be removed, and then you can’t switch on/off the meter remotely.

Lock

No, it is TTLOCK model.

It depends on the positioning distance and where you put the gateway. One app account can manage multiple gateways, and one gateway can manage 2-6 locks, but due to the Bluetooth communication distance (generally 10 meters), basically one gateway can also connect 2-4 locks. Customers can use the same account to bind gateways in different geographical locations, and bind the corresponding locks at the same time. If the gateway is placed indoors, it is basically the gateway lock, because the penetration power of Bluetooth is poor.
