Good day, We make use of POW devices to monitor voltage and power consumption on our campsite. We would like to suggest some improvements for the APP: - Add the Rate function to the POW Elite devices, as is available for the POW R3. - Create Voltage Graphs for all POW devices, to allow users to view if-and-when voltage drops or spikes occur. I believe this would add value to the APP and allow for better diagnosis of power supply issues, as is common with Eskom in our country. ---

Agree but please also add the ability to switch off power based on voltage, same way you can for amps and power. ---

Yes I agree too, by adding such feature would be a very usefull function for many people out there. ---

And depending on the voltage, turn the payload on and off. Very relevant for solar backup systems. ---

Hi guys, I have installed a POW (ring) CT device and surprised to see it does not have Unit Rate as an input in the firmware. Any plans to include this in the future? ---

Is there any way to see minus sign in Current on POW CT in ewelink app or ihost, in fact to see producution of solar cells because current on POW CT is minus: ![image](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/6/6d77094c98cc28ae78246211d8fccde9d0622d56.png)
