Tasmota blind integration with slider wanted

iz3man · April 26, 2020, 10:57am

I have the wonderful irhvac (based on tasmota_ir) software installed on one of my WemosD1 modules. And there are some digital IOs unused, so I thought why not use them, and connected a blind’s remote which has three buttons. One for up, one for down, and one for stop. Those are non latching switches. They trigger the signal, and you need to press stop at the desired position of the blind or it will completely open/close it.

The hardware is quite simple. GND connected to GND, and D[6-8] connected to UP/STOP/DOWN. Then Tasmota has assigned RelayInversed to each of them and PulseTime of 0.2s. Works nice with 3 separate switches.

But I’d like to add a slider to it like of of these for my Shelly Shutter module:

Is there some custom component that does what I want? Measure/input the time it needs for a complete full open/close and then calculate the open/close time to get to the desired percentage?

After typing the long post I guess this is already integrated in Tasmota. Damn, I should google more before I type … We’ll see, maybe I still need your help

Ok. I think it doesn’t work with my setup. First of all I guess tasmota_ir doesn’t have shutter support included, and I really don’t want to control the motor itself but only it’s remote control. No direct attached motor drivers modules or anything like that. And the logic is different as well. I do enable the motor with a press of a button, but it’s only a pulse, and the motor won’t stop when i release the button. It will need to press a second button.
Any ideas?

@Vaclav_Chaloupka made this script to control his blinds. Here is the code, might be usful for you:

/*
 Sonoff 4ch (ESP8285) MQTT sensor for shutters
 Generic 8285 module
 (or 8266 module,  FlashMode DOUT!!!!!)
 1M (no SPIFFS)
 Reset method: ck
 
 RX <-> RX !!!
 TX <-> TX !!!
Functionality:
 Push button for <1s - cover will go till the end. If I hold it longer, shutter will stop when I release the button.
 When I push the button during movement, it will stop
 
Roller shutters with horizontal vents:
 When I press button once, it will stop leaving the vents open. When I press it it again (or if the cover is past the open vents position), it will go till the end (both up and down)
 When I sent the cover to position 1, will will leave vents open
Tilt
 For blids, there is a separate function to control tilt. When I stop the movement, it will automatically tilt to the tilt tilt before it started moving
 For blinds with tilt, the behaviour pushing button for <1s and > 1s works differently than for roller shuuers (<1s pushes are meant for tilting)
The position is based on measuring the time for the shuuer to go fully up and down (and to the open vent position and for tilting blades)
