    Does anyone know of a Tuya switch with triacs instead of relays? Should have 6 channels (or more).
    I only found this 3 channel model here: Link

    I think that either no-neutral devices or dimmers are using triacs. Why do you need a device that uses triacs, specifically?

    My 8-channel relay card (this: Link) is consuming too much power, when all (or most of the) relays are active. Also, I can hear the relays switching at night.

    Maybe I should throw out the mechanical relays and use MOSFET-relays like this instead: small MOSFET relay or these ones Omron G3VM line. The floor heating valve actuators that I am switching with the above mentioned card only have 2 watts power consumption anyway.

    I finally decided for the Omron G3VM-601EY model. They have 600 volts peak and a dielectric isolation strength of 5000 V (just to be on the safe side). Only thing to add is a resistor on the LED side. To tell from the specs something between 330 and 1000 Ohm should work with the 5V for the mechanical relays. Max. current on the power side is 100mA, far more than what I would need. They also have a model (G3VM-601CR/FR) with 600mA, which would allow to switch a 140 Watts load, in case anyone needs higher output power.
    Will add photo of the pimped relay card on the above mentioned page.

    Sure, please consider making a full teardown/test if they were not shown on our forum before.
