I need some help with my mqtt cover setup for my venetian blind.
I have shelly 2.5 with custom Tasmota (because of if else function). I have configured two shutters, one for opening and closing, the second one for tilting. I use simple rule, that setcloseposition for tilting, when main shutter closing (running down). The next rule setopenposition for tilting when main shutter opening (running up). The main problem is when i use button to open shutter, tilting does not update in home assistant, but it works in tasmota.
I have tried mqtt discovery which added automatically tasmotized shelly to HA, but when tils resets by tasmota, slider does not update.
I have tried also mqtt template for cover and is has the same problem.
Can you please post your Tasmota configuration?
I am faced with this challenge too.
My use case is venetian blinds in a fully open position or fully closed position or closed position with a specific angle to let in light but block direct sunshine.
i don’t have access to my computer during this weekend, but i can help give you some hints what you have to set. I know that tasmota brings better venetian blind support, but i am using my solution for about six months without issue.
you must compile your own tasmota build where you allow “if else functions” (Rules - Tasmota).
prepare two shutters (Shutters and Blinds - Tasmota) and do Shutter calibration. First shutter will be set with fully open and fully closed times. On second shutter set times for tilt (it could something around 1-2 seconds)
you have to prepare rules:
here are rules which i use:
My venetian blind act like this: when it goes up (fully opening) the tilt is opened, but when it goes down (closing) the tilt is closed. So this rule is used to change shutter2 (tilt) to close or open position every time when shutter1 is moving.
on Shutter2#Position DO mem1 %value% ENDON
on Shutter1#Position DO var2 %value% ENDON
on Shutter1#Direction!=0 DO var1 %value% ENDON
on Shutter1#Direction=0 DO IF (var1==1) ShutterSetOpen2 ENDIF ENDON
on Shutter1#Direction=0 DO IF (var1==1) var1 0; ShutterSetOpen2; publish stat/shelly25/SHUTTER2 ENDIF ENDON
on Shutter1#Direction=0 DO IF (var1==-1) var1 0; ShutterSetClose2; publish stat/shelly25/SHUTTER2 ENDIF ENDON
The second rule I use for control of venetian blinds with 2 buttons - Single (tilt fully), Double (tilt for 30%) and Hold (fully open or close blinds). Double click is not very accurate and i don’t use that much. Instead of that i fully control blinds with Home Assistant automations.
on button1#state=3 do power1 toggle endon
on button2#state=3 do power2 toggle endon
on button1#state=10 do ShutterOpen2 endon
on button2#state=10 do ShutterClose2 endon
on button1#state=11 do var3=%mem1%+30 endon
on button1#state=11 do if(var3>=100) shutterposition2 100 else shutterposition2 %var3% endif endon
on button2#state=11 do var3=%mem1%-30 endon
on button2#state=11 do if(var3<=0) shutterposition2 0 else shutterposition2 %var3% endif endon
Thanks for the repsonse. It might take me a while to report on any progress I make.
I have the same continental European venetian blinds outside all my windows. But with a Swiss style button. UP and DOWN with mechanical interlock. A soft push for momentary and a hard push to make the button stay pressed which will pop the other button out. The blinds have built in end stops which stops the motor when fully open or closed position is reached.
My research so far:
Shelly 2.5 Stock firmware is useless. The relays are really fast 50ms but the firmware in Blinds mode(realay Interlock) gives very poor control over the relays when using the buttons. Feels like random delays of up to 200ms to start the relay and some random delays of up to 300 ms when you release the button. Useless for people who have fast motors. Useably for me as a tilt from closed to horizontal takes 1700ms. But far from ideal.
Compling Tasmota won’t be a problem.
Shelly 2.5 with ESPHome April 2020
I need to learn YAML. Several hard coded values that need substitution and individual tweaking for my blinds. Love the power monitoring to determine that the blind has reached the endstop and then it turns off the relay.
Shelly 2.5 with stock firmware and MQTT August 2021
Have not looked properly at this yet. Not sure if it will work with tasmotized Shelly 2.5
Sonoff 4 Relay switch with Homebrew MQTT firmware March 2020
This compiles only with older libraries from expressif for ESP in Arduino. Which means that it is vulnerable to WiFi Frag Attacks. Also the author metioned several times if he where to do it again he would do it all in ESPHome.
My nearly final solution is ESPHome using the cuurent based cover from Oct 2021 with some tilt presets and some lovelace custom goodness. Love Tasmota and the new tight integrations for it, but ESPHome rocks with HA.
I will link to my final solution here as it will be posted in a separate thread.
Code below. It can be improved, but it works great and I don’t have the time to make it nicer.
# To do:
# add an variable for the time it takes for the relay to close and the motor to start moving - relay_motor_reaction_time
# this time is used in all tilt operations
# then the tilt angle can be passed with the GUI as a 0-90 slider or presets
# the calcuation for the tilt_motor_time is (TiltAngle/90) * (tilt_to_horizontal_duration - relay_motor_reaction_time)
# the tilt is then acheived by activating the realy with relay_motor_reaction_time + tilt_motor_time

# Chris notes
# This is based off the Shelly 2.5 example in the current_based cover
# https://esphome.io/components/cover/current_based.html
# https://esphome.io/components/sensor/ade7953.html?highlight=ade7953
# The obstacle detection amperage is not set in the example
# Shelly 2.5 current measurement with ade7953 has Relay 2 on Channel A and 1 on B - the example is incorrect
# The samnple code has the open and close realys reversed which is incorrect
# The operation of the cover:
# GUI - The time in open_duration and close_duration is used for the slider
# GUI - When a hardware end stop (current_a or current_b below threshold) is reached the slider will jump to 0 or 100, self calibrating itself
# Hardware switch - A long (>2000ms) momentary push will activate the realy until an end stop is reached. A momentary Up or Down push will stop the relay
# Hardware switch - the Feller Storen switches can be set to momentary only. This is the reccomended way for OCD people like me who don't like pushed in switches
# Getting some Tilt functionality
# Option 1 - Tilt % preset buttons in the GUI using Down relay for 1700ms followed by up Realy for x ms. Not sure how to do this best. Exposing relays OR sending Down 1700ms Up x ms in Lovelace with automation or something
# Option 2 - use template cover with modified github.com/InToSSH Tilt Code
# Option 3 - Build presets into the ESPHome YAML and expose them somehow as buttons in Lovelace Use Switch Template for this for virtual switches.
# cover.on_open and cover.on_closed trigger when endstops are reached use with text sensor to show status
