In-wall connector for blinds

[Steve Caster]

Hi all,

I am trying to migrate my manual up/down sensor for my blinds with a mysensors solution. I would use this PCB (solder off the USB/connectors :http://www.benl.ebay.be/itm/1PCS-DIY-Kit-5V-800mA-Regulated-Power-Supply-AC-DC-220V-to-5V-Power-Convert-/331476522266?hash=item4d2d8a551a ) with an Arduino nano , nrf and the following relay:

Does anybody see an issue with this? Safety? Programming etc?

Kind regards

Steve
