Review: Shelly 3EM + EcoFlow PowerStream - Whilst this is a 3 phase meter, it is equally happy on a single phase system - just link all 3 inputs together. It's very easy to install, but does require a 240Vac supply - easily found if it's being installed into a consumer unit. Wi-fi connection is simple enough but will require a smartphone/tablet/laptop etc to get it set up. The Shelly app works well and keeps a log of energy usage for its own graphs. The meter also understands the concept of feeding energy back into the grid (PV etc). This model can also be integrated into the EcoFlow system to control the output of their PowerStream micro-inverters to maximise the usage of "home grown" energy before taking expensive units from the grid. It works well in that respect.
Review: Ecoflow and HASSIO compatable - If you have a powerstream the shelly will allow you to get the true grid pulled watts and you can get rid of all the powerstream plugs ,allows automations with powerstream . this is a must .

If you have a powerstream the shelly will allow you to get the true grid pulled watts and you can get rid of all the powerstream plugs ,allows automations with powerstream . this is a must .

### ⭐⭐⭐⭐⭐ Get one if you use a Ecoflow Powerstream!
*by U***S on 7 November 2024*

Monitors energy consumption brilliantly, I bough this as it is now compatible with the EcoFlow Powerstream, no more need for smart plugs, this device monitors whole house consumption and lets the PowerStream micro inverter know what to feed in to the house.
