Hey, I got a V2 device which has the BL0939 chipset for powermetering and isn't showing the zero cross detection. Is someone further or can we investigate the reason to find a solution?
Hi, I found that the Zero Cross Detection template is also available for Sonoff DUAL R3. But I ask myself, is it useful if DUAL R3 only supports power metering and relay switching? It does not support dimming etc. Is not this setting just a waste of resources and energy? I don't know, IRQs etc. 🤔
