Yes, works fine and problem free for almost 5 years.
Upgraded to Domoticz Stable 4.10717 a while ago and now that I look at it,
it's reported as Fakro ZWS12 Chain actuator 12VDC (???), unprotected and no polling.

Kre10, some remarks: - Nested IF is not allowed (remove the outer IF) - Use the IF with the blue star when ELSE is involved (correct for your inner IF) - use a Dummy Switch Device and let it switch ON at 6 and switch OFF at 22hr (with the Timer of the device) - combine this Dummy Switch in the IF ...

I am using a DC12V - 200mA charger

I think 200 mA is to weak.
Look for 500ma.

Build it like this:
Check via the blue button "Show current states" if On/Off is correct (or Open/Closed?)

Spoiler: show

(Remote control = On)

So many words and no picture ...

Take a good look at the many examples here: https://www.domoticz.com/wiki/Blockly

Create the combinations like
(Nacht slot = Off) and (Remote control = On).

Start with "and" block
Add a left block: (Nacht slot = Off)
Add a right block: (Remote control = On)
Do the same for the Else if

Try %20 instead of the space?

It sounds like Z-Wave association, that is a direct connection between Z-Wave members. Normally this is arranged in the table on the right-hand side here: https://www.domoticz.com/wiki/images/d/d0/ZWaveNetworkInfo.jpg from here: https://www.domoticz.com/wiki/Zwave_network_and_group_info Check this ...

Start with the AND block

I think Sunset and Sunrise is a time moment and not a time period. Start with a simple dummy switch: IS_DARK. IF (Time >= Sunset OR Time <= Sunrise) AND IS_DARK=Off Do IS_DARK=On IF (Time < Sunset OR Time > Sunrise) AND IS_DARK=On Do IS_DARK=Off If this works .. You can use IS_DARK in other Blokly's ...

Make it
(....) AND ( (Camilla Telefoon=ON) OR (Mario Telefoon = ON) )

Start from fresh. Your If block is ok. take an "and" Blockly Then there is on the left space for a "=" blockly and on the right side for a "=" blockly Add on the left topolino and On Add on the right minnie and On Study the wiki http://www.domoticz.com/wiki/Blockly and look careful for the ...

First pick the "and" block.
Put a condition to the left and one to the right.
Left: topolino=On
Right:minnie=On
Make this:
(topolino=On) AND (minnie=On)

And NOT as yours:
topolino=(On AND (minnie=On)

timer rules

Tested with stable version 3.8153 on Win7:
the timer function of the Setpoint dummy works correct

This command: adapts a dummy setpoint with IDX=80 to temperature=22.
Tested with stable version 3.8153 on Win7.

I assume you can use this command within a Blockly to set a temperature.

user variable to the dashboard so it can be modified, for example a "required temperature" variable

Use Dummy hardware.
Create Virtual Sensor
Select Thermostat Setpoint

This Setpoint can be used in Blockly to compare with a temperature sensor and take action.

First pick the "and" block.
Put a condition to the left and one to the right.
Left: topolino=On
Right:minnie=On
