Good product

Assembled, working.
By setting the power alarm the detachment is too fast, all it takes is a current peak that jumps immediately.
A delay should be inserted at the firmware level

Great product

Works excellent as described with power & rate monitoring and cuttoff features.

Works perfectly

I had it installed in the cavity behind the meter box, with a bypass just in case, and have it connected to a 16A hot water service. Works perfectly and saving me a fortune in electricity.

Product title

Hi...I need a smart power meter up to 40A AC220V...Is it possible..plz ...(As item power elite or power origin) for use households

Eccellente prodotto

Prodotto davvero fantastico, fa il suo dovere, unica pecca non poter vedere i consumi graficamente sia mensili che settimanali.

Great product!

Installed POWR3 to monitor and control our electric oven. Works great. We can now switch it off in case of emergency. Sometimes, we left home and forget that we have something cooking in the oven.

It would be great if there is a 35A relay (up to 7000W). We have an induction cooktop. We also would like to be able to monitor and switch off in case of emergency.

Powr3 winner

excellent reliable product.
possible improvements
---packaging, should be in circuit breaker style container to fit with power board formats.
---ewelinkweb not good enough, needs to be a "Responsive" app auto sizing and more display options.

Pow 3

Wanted this as a power monitor and not concerned about power switching capability. Interesting to see that the connection cabling provides a capability to provide a switched and a non switched output using the existing high power connectors; by repurposing one of the N connections, (I doubt this was intended by the designer!). For me perfect for just power monitoring but a bit disappointed in that the output has to be switched on before it will measure and report power. Must be a software limitation as there seems no logical reason from the circuit why the power monitoring part of the unit is not active all the time. Not yet checked the accuracy of the power monitoring.

The smart plug with the power I have been looking for

I have been looking for such a plug to control my oven which consume just under 4kw (about 16A). Obviously the previous iteration where not enough being limited to 16A.
With this one rated for 25A I had great hope.

So far it is behaving brilliantly. Even after a couple of hours of constant running the box is barely warm and nothing seems to overheat.

I will open it in a few days to check the inside and make sure nothing looks like it is melting. If it is as I expect it to be then I will probably buy a second one to control my other oven.

Having the power consumption is important to me as it allows me to know excatly how much my bakery is consuming.
