I’m wanting to implement a whole home power monitoring solution. I’m not interested in any of the DIY options others have used, as I’m not a electronics tinkerer. However, I can handle a plug-in-play solution like Shelly or Sense. I’m pretty sure the Sense offering is too pricey and unreliable with device discovery. Which pretty much only leaves a Shelly device.
I’ve done some research on their two options: Shelly EM and Shelly 3EM. And to be honest, it all sounds a bit confusing given not having an electrical background. Every time I look into these devices I walk away with a different understanding of their use/installation; which has lead me to writing this post.
HOME: I live in a typical single family home in the United States; more specifically Texas. I point this out as it answers the question of how many power phases I’m dealing with (single/split phase). Here is a shot of my breaker/main box.
That said, here are questions for those in the know:
- What Shelly device best serves my needs?
- If you know, please explain why you recommend said device?
- What information does HA integration provide on power use?
- What is the proper wiring procedures given the image above?
PS: I’d really like to hear from community members that have installed/used the devices.
