Smart Stackable Power Meter (4-Relay)

I have purchased this for my tank room to control my pressure pump and heat pump, both draw approximately 10 to 12 amps each, however the relay cannot handle when there is a surge in the amp requirement from the pump. Example when the tap is on this triggers the pressure pump to on, the relay shut off automatically and show error light, as a alternative work around, I have connect the pressure and heat pump via Contactor. Due to this setup, I will loose on the tracking of the built in power metering.

I haven't been able to use these yet. The problem is they are too big to fit in my electrical enclosure. Ended up using the smaller relays driving the existing contactors instead. Lost the power metering function but can''t be helped.

The product works pretty ok. The only problem is my water pump that when it starts it produces a current peak and triggers the OPS... Do not know how to handle that yet. Hope Support can contact me to check it.

I have been able to use this on my project. It provides what I need to control and monitor the device consumption connected to this product using the API.

I purchased 2 stack 4 relay module and 1 main unit for test purposes. It’s simple and reliable.
I do miss in software, that the physical buttons on the module can’t be disabled. It would be a cool feature.
Also a 32A version would be nice too.

But except those, just awesome! I will purchase a few more in the future.

This was a great option for us to maximize capability and provide full automation control over our electrical. The additional rate & power management and switching features are excellent.

Having installed in my shed out the back of my house I find it's fantastic to turn the shed on and keep track of power consumtion of tools on charge and simply turn off the shed when chargers are completed.
