Fantastic, providing their is sun when you want to open/close blind and their is no snow obscuring the solar panel.


What happens when you want to shut the blind to avoid being woken by strong sunlight in the morning once their is no more sun ?
The control unit contains a battery silly.

Do you know how a Tesla car works? The charging station charges the battery and the battery powers the motor.

In this case, the solar charges the battery and the battery powers the motor.

600 operations are possible without any sun, according to Velux which should be adequate even for a Zurich fog-filled Autumn.

Don't worry, I do it too.

Sometimes I forget how old some of the stuff is in our place - I had to replace a component in the board a control unit for a "non-velux" roof blind the other day and the part gone obsolete ten years ago.

Still, I took the opportunity whilst I had the lid off to to add a ESP8266 (wifi/microcontroller) so I can now control it using Alexa or in a multitude of other ways. (no stick needed!)

Yes, I like to replace the proprietary controllers with ESPs to have more flexibility.

I tend to just wire the modules up to the existing control switches and keep everything else as is. It also means I can control the unit from the existing panel.

The ESP8266 can quite easily switch a 5V i/p but this case though I needed to change the PSU as the existing 5V supply wasn't enough when the wifi was transmitting. (But the supply was defective anyway so needed replacing).

I've been using WEMOS D1 mini boards as they have a small footprint, come with 3V3 regulation on board and can be programmed and/or powered from a standard micro-USB connector rather than fiddling around with serial port level converters etc

(And you can get 5 boards for 12CHF !)

Sorry, I'm digressing...

For some, I replace the whole thing e.g. garage door controller as the stock ones are typically not secure.
