      Great product, really useful.
      really poor packaging, the box arrived completely smashed.
      Thank god, it was not damaged.
      inappropriate package for something electronic with a screen, it could have been completely busted, be more careful.

      este produto veio usado, todo puido, cheio de manchas e o produto não vem com a bubina .
      não reparei se estava como usado na compra, acredito que não.

        Q: solar will it mesure power from solar cells back to the grid ?
        A:
        Solar cells give DC. After Your inverter to the grid AC might be measured. The transformer would measure current both direction, but care the connection scheme. This is intended to follow your consumption from grid.

        Q: Does the display stay on permanently or do you need to press the button every time to activate it?
        A:
        The display is always on and if there is a power failure it will carry on from where it left off once the power is restored. You will not loose the information.

        A:
        As said the device will function within the specifications as described. Not certain how the temp. measure sensor will be mounted. Suggest to mount the device direct on the frame to minimise vibration which could damage it .

        Q: what temperature does this read? does this read the heat of unit itself? ambient temperature? or does this need a thermocouple/temperature probe to read an external temperature?
        A:
        Thermocouple unit plugs into the unit with a small white 2 pin connecter. Temp reading will come from wherever you place it, inside DB Board or the end of the probe can stick out measuring the air temp.

        Q: Has anyone hooked this up to a Sonoff or eps8266/esp32/rPi etc?
        A:
        Interestingyou ask this, as I want to do exactly the same thing. There's no default, user facing, method. I've yet to take it to bits to look for some other interface - likely debug test points on the PCB. Might get lucky and there's a socket inside. You mention Rpi - as a worst case, I was going to use a pi with a elcheapo webcam runing a python script to visually read the display. Well, a bank of displays, I've more than one. When I get that far through my turbine build, I'll be back to divulge my learnings. If you get there first, pop back and let me know.

        Q: can this unit detect a spike in current say less than a second. For example when a compressor start? I need to know the max current draw. can it log max values
        A:
        The consumption value is refreshed approx. 3 times per second and it is difficult to figure out the maximum value. The maximum value is not saved.

        A:
        make sure the CT is around the hot lead only. if not it will report false measurements.

        A:
        I think according to the instructions it can measure kWh energy or power factor PF. I bought it but haven't installed it yet, and the instructions say that it is possible to choose.

        Q: Wired as per included diagram the screen lights up - with the probe connected, displays temperature - but I'm getting no readings through the CT. At all. Any clues? On a different note, anyone seen a device like this that speaks MQTT or is intended to couple to a microcontroller for logging etc?
        A:
        Pass the wire you want to measure on the CT through the ring current transformer. Then connect the power adapter in place.

        A:
        You can select when purchasing whether you want the 10amp or 100amp versions as well as a closed current transformer or one that can open and go around the wire instead of taking the wire out and feeding it through and connecting again

        A:
        CTs cannot measure DC, by laws of physics. You need a shunt with voltage sensing to calculate the current, or a hall effect sensor setup with de-gaussing etc.
