@mikeones I apologize to get back to you so late. You might already have figured out a way but I wanted to let you know that after many days of testing my relay actuator with OpenHab, I'm very happy to tell you that it's working flawless. No issues with the stuffing inside the gand box whatsoever. I have not seen any other option to power the arduino thru 110V - 240V. Using a cellphone charger seems to be common.

Please let me know if you have any other solution, I would certainly give it a try.

Thanks!

Mate, I like what you have done!

I have a similar set up as you, with the only big difference being that I use Vera 3 and you use Openhab. I also use Autovoice and have that going all the time on a couple spare phones and tablets, and they are always listening. I have named my automation set up, so when I say its name and then a command, it goes and does it. I was using Ok Google, but I wanted to feel more futuristic lol so instead of asking google to do something for me, the 'person' in my home automation does it lol

Anyways, I actually have a question about your specific example here... I have the exact same relay, but I was never able to get it to work. I see that for this example you were only using one of the relays, which I admit I never tried, but can you share as to whether you have ever got both relays to work? I would love to know, because the stupid thing almost sent me crazy! I have two of them and could never get either of them to work.

Please let me know if you have any other solution, I would certainly give it a try.

Thanks!

Any other options for powering that node? Any safety issues with having a charge stuffed in a gang box and left inside the drywall?

Thanks in advance
