A-OK AM43 Blinds motor

[roblom]

Recently I bought a A-OK AM43 Blinds motor which has arrived. I installed it and works great.
I found this script

Now with this python script you can send bluetooth commands to control it. Some theory behind the script, it's using the following curl command

Code: Select all

curl -i http://localhost:5000/AM43BlindsAction/"Action"

The "Action" options are
number 0-100 --> Set blinds to position wanted
Open --> Opening blinds
Close --> Closing blinds
CheckStatus --> Get battery status, current position and light in %

I'm able to control it using my Raspberry Pi. Of course now I also want to integrate it in Domoticz. For a noob I came quite far already, if I say myself. I have the battery and light (sensor) percentage already in a virtual sensor.
The device has also physical buttons for up and down (and theoretical also the app that can control it) so there is a "position" parameter (number 0-100) that can be read out to indicate the current position.

So my question is, what's the best approach to let the position of the virtual device in domoticz keep in sync with the real position? Because when someone uses the physical buttons on the motor Domoticz should also update. I think this only can be done by using a time script that updates with a certain frequency but can this same virtual device then be used to control the blinds too?

Second question; is there a possibility to combine this data all together in one virtual device? So a position slider, open, stop, close button and a battery status?

The script I have currently (work in progress).

Code: Select all

The response to "CheckStatus" is

{
    "Blinds1": [
        {
            "battery": 79,
            "light": 0,
            "macaddr": "02:BE:3A:9E:6E:0E",
            "position": 0
        }
    ],
    "status": "OK"
}

	--		local ResultData	= item.data

				dz.log('HTTPResponse status is ok',dz.LOG_DEBUG)
				local BlindsStatus	= item.json.Blinds1[1]			
				if BlindsDeviceBattery		then BlindsDeviceBattery.updatePercentage(BlindsStatus.battery)		end
				if BlindsDeviceLight		then BlindsDeviceLight.updatePercentage(BlindsStatus.light)			end
				if BlindsDevicePosition		then BlindsDevicePosition.updatePercentage(BlindsStatus.position)	end

In theory yes but it is quite challenging to keep the virtual blind aligned with the physical blind if you need to ensure it will stil work if the two modes of operation can be (almost) simultaneously.

Second question; is there a possibility to combine this data all together in one virtual device? So a position slider, open, stop, close button and a battery status?

A blind percentage could do that with the exception of battery status
