Stop blind partway down?

[omegahm]

Hi @starkillerOG

This is more of a question than an issue.

When I use the app that followed with my blinds (Motionblinds) I am able to press DOWN on a blind, then press PAUSE, then press UP. This will let the blind first close, then stop, then open again. When I try to script it, the blind doesn't seem to listen to the Stop() command. Am I doing something wrong, or is the blind not capable of listening midway in this manner?

This is my testing script.

import datetime
import time
import logging
logging.basicConfig(level=logging.DEBUG)

from motionblinds import MotionGateway, MotionDiscovery

m = MotionGateway(ip = "XXXX", key = "XXXX")

m.GetDeviceList()
m.Update()

blind1 = list(m.device_list.values())[0]
blind1.Update()

print("Closing blind...")
blind1.Close()

print("Waiting for 2 seconds...")
time.sleep(2)

print("Stopping blind...")
blind1.Stop()

print("Waiting for 2 seconds...")
time.sleep(2)

print("Opening blind...")
blind1.Open()

For full context, I am trying to integrate my blinds with my Fibaro Home. This is using Lua for scripting and my QuickApp is set up like so:

function time()
  return os.date("%Y%m%d%H%M%S000", os.time())
end

function getData(token, macAddress, state)
  return json.encode({ 
    msgType = "WriteDevice", 
    mac = macAddress,
    deviceType = "10000000",
    AccessToken = token, 
    msgID = time(), 
    data = { operation = state } -- 0 is close, 1 is open, 2 is stop, 5 is status
  })
end

function QuickApp:operate(macAddress, state)
  self.socket = net.UDPSocket()  
  self.socket:sendTo(
    getData(self.accessToken, macAddress, state), 
    '238.0.0.18',
    32100
  )
end

Here I can then use operate(macAddress, 0) to close the blind and 1 to open. The blind doesn't respond again before it's closed completely.

Do you have any tips? Thanks!

I don't see anything wrong with the python script.
My blinds (motionblinds) respond just fine to the stop() command.
I also have not seen any complaints from the HomeAssistant users about the stop command/button.

There is not much special about the stop command.

Maybe your RF signal from the gateway to the blind is weak. While the motor is running and creating some electrical noise, it is not able to receive commands????? (Wild guess)

Have you tried placing the gateway/bridge closer to the blind?

We have 8 blinds in the house and the gateway sits about in the middle of them. I've tried with the mobile app now and it also only responds about half of the time to the stop command, which seems to verify your suspicion about bad RF signal?

I am not well versed in the UDP protocol. Is there a difference whether I multicast to 238.0.0.18 vs. the specific gateway IP?

Is there a difference in gateway bridge? The one I have is a Coulisse CM-20.
