    up and running in 5 minutes with my Alexa

    I attached a 24VDC supply to this thing, downloaded the WeLink app on iOS, and was able start toggling the relays from the cloud and my Alexa within 5 minutes. I don’t quite understand why the WeLink app wants access to your phone’s location (GPS). I guess you could set up your account and device somewhere not at home if you were super concerned about that being a privacy issue.

    Inching mode works great for trigging a momentary switch press. Being able to customize it in 500ms increments seems really handy too. I tested this and it works with no issues with triggering the Craftsman garage door opener at my home. Using this instead of buying a garage keypad or additional programmable wireless remotes would be most cost effective. That said, if your wifi or internet isn’t consistent, or the thought of someone figuring out your account and remotely opening your garage is a solid fear of yours… maybe this isn’t a good solution for that.

    Nope sorry

    These can not control a DC circuit. They can control AC but not DC. My use for it went out the window because of this. It shows you can work a DC voltage but you can’t. It works off DC voltage but it does not control it. Shame would have been put to good use.
