HOME AUTOMATION: Teptron move control from Linux

UPDATE: this method does not appear to work with the latest Teptron Move firmware. The developer of csrmesh is looking in to the problem but there is no current solution for controlling the Teptron Move from anything other than the app.

My biggest pain point with the Teptron Move automated blinds device at the moment is the lack of app updates and any functionality other than just simply commanding the blinds from my phone. Because of this I have basically removed the devices from my blinds. You can read more about my issues with the device in an old post.

I recently started to think about how I could potentially expose the CSR bluetooth mesh that the Move uses to my wireless network. This would allow me to get the automation I'm looking for out of my OpenHAB controller. I came across a project on GitHub claiming to have reverse engineered the CSRMesh protocol for the Teptron Move and decided to give it a shot.

I did a little more digging and found some posts on the domoticz forums talking about how to integrate the linux script with the domoticz home automation solution to automated the Move units, so I decided to investigate the possibility of integrating the devices with my OpenHAB system.

Installing The Script

Git is not installed on the Ubuntu image for the Pine64. Install with the following commands:
 apt-get install git  

If it's the first time using git on your machine you need to:
  • Generate an rsa key 
  • Follow the Github instructions to add the rsa key to you github account
I also found this article useful to debug my problem.

If you don't follow these steps you will get the error:
 Permission denied (publickey).  
 fatal: Could not read from remote repository.  

Now create a new directory clone the csrmesh repository into that directory:
 mkdir Downloads  
 cd Downloads  
 git clone  

Build and install the project:
 python build  
 sudo python install  

The script also needs the bluez software installed:
 sudo apt-get installed bluez  

If you are trouble getting your bluetooth running on an Raspberry Pi 3 with OpenHABian I have explained how I did it in an older post.

Bluetooth Setup

If your device doesn't support Bluetooth natively you will need to do some work with a USB Bluetooth adapter to get connected  to the Move units.

Insert the USB adapter in to the Pine64 and run the following command to check the device was recognised:

 If the device was recognised by the linux kernel you should see an output something like this
 [449253.083342] input: Logitech Logitech BT Mini-Receiver as /devices/soc.0/1c1b000.ohci1-controller/usb4/4-1/4-1.2/4-1.2:1.0/input/input5

 [470193.118153] sunxi-bt bt.28: block state already is 0  

We can now run one of the bluez commands to check if the bluetooth adapter was recognised and is available for us:
 hcitool dev  

If everything is in order with your setup you should see an output like the one below and you can continue on to the next section:
 ubuntu@pine64:~$ hcitool dev  
     hci0  00:1F:20:51:CC:AA  

If you don't see any devices listed then you will have to do some work to enable the Bluetooth adapter. You should have a utility installed called rfkill that is used to enable and disable wireless devices. If it's not installed you can install it with the command:
 sudo apt-get install rfkill  

Run the following command to see your connection status:
 ubuntu@pine64:~$ rfkill list  
 0: sunxi-bt: Bluetooth  
     Soft blocked: Yes  
     Hard blocked: no  
 1: phy0: Wireless LAN  
     Soft blocked: no  
     Hard blocked: no  
 2: phy1: Wireless LAN  
     Soft blocked: no  
     Hard blocked: no  
 3: hci0: Bluetooth  
     Soft blocked: Yes  
     Hard blocked: no  

The following command will remove the soft block on the Bluetooth adapter:
 sudo rfkill unblock bluetooth  

Now run the "rfkill list" command again and you should see the soft block has been removed.

Success! The Bluetooth output has been enabled and we should be able to see available Bluetooth devices if we run the hcitool dev command again. We can confirm the device is working by scanning for available Bluetooth devices:
 hcitool scan  

The above command will scan for regular Bluetooth devices but will not be able to to see Low Energy (BLE) devices. In order to scan the available BLE devices we need to run the command:
 sudo hcitool lescan

Testing The Script

Typically we would do a hcitool scan to get a devices MAC address, but the csrmesh network doesn't allow us to do this (at least in my setup). I've connected to the CSRMesh network from my Windows laptop and used that connection to gather the device address to include in the script.
The address I grabbed from my PC was: BTHLE\Dev_43c55b040006

The Github documentation tells us to format the command in the following way:
 ./bin/csrmesh-cli move --pin 8888 --dest 43:c5:5b:04:00:06 --objid 1 --position 255  

You need to make sure you are running this command from within the csrmesh folder that was cloned earlier. If everything worked you should see your Move unit move to the set position and the output:
 Running: gatttool -b 43:c5:5b:04:00:06 --char-write-req -a 0x0021 -n 0fe2bd00809bb9d83b76b48585673a77b747ff  
 Characteristic value was written successfully  

Note: The only gotcha here is the pin for the Move units. Here you will need to remember the password you set to the CSRMesh network when you first set up your move unit. If like me you have forgotten this, perform a factory reset on the unit by removing the battery, hold down the stop key then re-insert the battery. The notification light on the bottom of the device should be on solid. Keep holding the stop key for at least 5 seconds at which point the device should be reset. In my experience you don't get any feedback that it has performed the reset. With the device having been factory reset you can restart the Android app and enter a new password.

The next step here is to now enable the device for use with OpenHAB.

I've written a post on how to get this script working with openHAB here


  1. I recently bought a number of Teptron Move and it has been one of the worst purchase for its price per unit. I am frankly fed up with it within a week of installing it. Like you mentioned the developers over promised on the functionality of the app, its only provides basic open and close functionality and from the other comments on the app site its been this way for a while with seemingly no updates as to when the other promised functionality will be available.

    The next two issue I have with it are that it can never seem to open or close to the calibrated positions. The next big issue is that it lost its bluetooth functionality after a week. It doesn't connect anymore to my phone, no number of reset, power cycle, factory reset, change of batteries, using usb power resolved this issue.

    All I have now is a device that doesn't do what it was sold to do, no control from phone with bluetooth. Its basically a pie of garbage.

  2. To git clone, surely just do:-

    git clone

    and don't worry about git accounts and ssh keys...

    1. Yeah most of the time this would work for me, but on the Pine64 I kept getting the "Permission denied (publickey)" error and the only way I could resolve was the set up the account and SSH keys properly. Never had this issue on the raspberry pi

  3. Is there any user-friendly way to determine MAC of the device?

    1. UPD: "hcitool lescan" works, you only need to kill the stock app on the phone (and maybe even turn BT off)

    2. Not that I know of, I was only ever doing this from the command line.

      I never had any issues with my phone's Bluetooth, what kind of issues were you seeing?

    3. что делать если move не работает. телефон его не видит. на самом устройстве горит красный индикатор а зеленый большой частотой мигает. пробывал сбрасывать настройки как указано на сайте производителя. все бесполезно

  4. что делать если устройство не работает. горит только красный индикатор и с большой чистотой мигает зеленый
