Thanks for sharing. I see you've even filled the topic field of the template, nice! Of course you can sync LED to the relay - just set the same channels for LED pin as you've set for the Bridge. The channels are used to group together things like buttons, LEDs, relays, etc. You can do this in this view: Did you attempt to run PowerSave 1 on your device? It should reduce heating and prolong power supply life.

>>21446984 Hi! Thanks for the swift reply. I still didn't deploy it, just testing it out. I'm gonna see about grouping the LED. Thanks

Is BL0942 working? This device may require SPI mode of BL0942, which is also currently supported.

It's spitting out some numbers, but I haven't calibrated it or put a load on it yet. I'll have time to test it properly this weekend.

When I look at this device I would never trust it to disconnect/switch 63A !

It will be on all the time, just for power metering. I have proper electrical equipment installed by electricians, and my circuit breakers are rated below 63A. But you're right—I would never recommend working with just these types of devices. I just wanted a clean way to measure power. We'll see how it goes; I'm not entirely sure if I'm going to deploy these yet. I'm going to run some tests before wiring it up.

I'm new to openbeken (I'm more of a tasmota/esphome guy), is there a way to sincronize the LED to the state of the bridge relay?
AI: Could you describe the specific steps you've already tried to synchronize the LED with the bridge relay state?
I haven't tried anything yet.
AI: Have you encountered any error messages or unexpected behavior during your attempts to synchronize the LED? If so, could you provide details?
I haven't tried anything yet.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
