    Hello,
    Is it possible to bridge the relay in the Tuya KWS 302 WF meter?
    Would this not interfere with the operation of the meter?
    I am being forced to do this by the unstable connectivity of the meter with the Smart Life app, resulting in the relay disconnecting and therefore the FV inverter.

    I have not seen this particular device, but it seems to me that bridging the relay should not affect the measurement. The measurement is done on the shunt next to it rather than on the relay itself :D .
    The only question is whether the firmware does not have some kind of "when the relay is open, give a value of 0" dependency, but this would have to be checked. On the other hand, you are unlikely to mess up the device with this - just specify the relay pins and put a jumper there, keeping the safety rules of course...,
    Helpful post? Buy me a coffee.

    I think so too
    The problem is probably solved.
    The cause of the shutdown was not a communication error,but exceeding the max voltage.
    I have now noticed that the voltage is set to 250V max.
    The meter overestimates the voltage by approx.4V.,i.e. the voltage from the inverter 246-7V,plus the overestimation exceeded the max.
    I raised the allowable voltage to 270V and it works.
    I close the topic
