Here is my Quick app for turning off synology nas with the hc3, and using wol (wake on lan for waking it up again)
First you have to enable wol on your synology nas
What it does:
It uses code user agents for optaining the servers sid for logging into the server and power down.
After installing the quickapp, put in your varibles in the varibles window for your nas server in the varible window ,except mac adress, then save.
In this first version you have to put you mac adress as hex int the code window, then save.
that will be fixed in next version.
See screen shot what text to search for and replace for putting in your mac address.
test and enjoy.
