Blind automation

[mcs51]

Attached a file with part of my Velbus installation. Blinds of module 07 are now manually controlled via buttons on the VMBGP4-20.

How to automate this based on time, light & temperature?

Something like:
a) from, let say 19:00 in the evening of day one and 08:00 in the morning of the next day, always open

b) when light intensity of the VMBPIRO-20 drops below 250 and outside temperature is above 20°C and inside temperature is above 23°C, close the blind

c) manual mode via buttons, but that is working fine

Being new to Velbus it’s unclear to me how to configure conditions a & b in combination with c.
Give me an Allen Bradley or Siemens PLC and the job is done in 2 minutes.
But with Velbus… …

Thanks a lot to add the necessary actions in the file for one blind so that I can learn from it and program all other blinds myself.

Regards
Alain

If virtual relays are needed, I also have 5 VMB4RYLD-10 modules and a second VMBGPO-20 in the installation.

Hi

I’m on a train right now, so can’t access Velbuslink

@mcs51

a) from, let say 19:00 in the evening of day one and 08:00 in the morning of the next day, always open

This is fairly easy

Create two virtual buttons on any panel

• One for Opening the blind.

• One for closing the blind.

Then go into the Program tab of the panel and set a time for each to be Virtually pressed (and released)

While you’re in the programme tab, check out the SunRise & Sunset options.

You can edit the table to suit your location.

Don’t forget to enable the Sunrise & Sunset feature, by “operating” the module (same context menu for accessing configuration)

b) when light intensity of the VMBPIRO-20 drops below 250 and outside temperature is above 20°C and inside temperature is above 23°C, close the blind

Now this is a little more complex and needs some thinking about.

I can’t remember if the VMBPIRO-20 has a combination trigger that you can configure. (I might be thinking of the VMBMETEO)

If it has, then create a trigger with the two conditions

Add an action to that trigger to Close the blind

Use the Advanced tab of an indoor device for the temperature threshold and configure an alarm channel to your 23°c set point, for “when above”.

Add an “inhibit when open” action between the Alarm channel and the combined channel of the VMBPIRO-20.

Give it a try and see if that’s what you want.

Good luck

Hello MDAR,

Closing of the blind based of ONLY outside temperature is ok using the “High alarm” output channel of the VMBPIRO-20.

To add the room temperature…
The Configuration Settings screen of the glass panel looks like attached file. No “alarm” or “when above” as you mention. Am I looking at the wrong place ??

Thanks for your assistance so far !

You’re so close…

Try looking in the Alarms tab…

You also need to activate the thermostat, as the error message states at the top.

Add an Address to the thermostat section to the panel you’re using, to expose the Alarm triggers.

(Right hand click on the Module name and choose “address”)

[mcs51]

Sorry but that address thing is unclear to me

the glass panel has an address: 0x07
the module controlling the blind has an address: 0x04

So who else does need an address ??

What should I understand by “thermostat” ?
I don’t use velbus to control room temperature, yet.

Indeed

But to use the features you require, the thermostat needs activating.

Please right hand click on the glass panel module, choose “address”

Hopefully the panel will be preselected

Look at the bottom and you’ll see there is a Thermostat tick box.

Apply the new address and magically, eight extra trigger channels will appear on the module.

You can’t do any harm, please feel free to explore and try things.

I appreciate your experience with other systems, so I need to reassure you that you really can’t do any harm by trying things in Velbus.

(I’m trying not to just “give you the answer on a silver platter” so that you get the pleasure of discovering the power and simplicity of Velbus for yourself. But I will continue to support your learning journey)

[MDAR]

Now that I’m at a computer and playing with your VLP file

It seems we can’t inhibit the High Alarm trigger of the VMBPIR-20 modules

You’ll have to use a Virtual Relay as a go-between

• Virtual Relay “follows” the High Alarm of the PIR

• Indoor “high temperature” alarm channel, inhibits the Virtual relay (when open)

• When all conditions are met, the virtual Relay will “close” the Scherm.

Does this help you?

If you need more complex functionality, your option might have to be a rule or logic argumnet in something like

• openHAB
• HomeAssistant
• Node-Red

NO

How to AND the “Alarm 1” from the glass panel with the “High alarm” from the PIRO so that the blind goes down when BOTH conditions are met ? Two actions 110. Down

I also configured virtual button 5 to drive the blind UP at given time, action 106. Up.

All actions on a specific “Subjects” are OR function, right?
How to get OR(AND(110.0 Down Alarm1; 110. Down High alarm);106.Up ZonW bak. Open)

Assistance is greatly appreciated!
