@achurak1 said in livolo Glass Panel Touch Light Wall Switch + arduino 433Mhz:
@Nca78, does that mean I can send high from arduino to this electrode thus imitating the touch? If so, would it be easier to do that or send the high/low directly to the HC238 (to A0 - A2)? It seems that in the first case I can also easily control the dimming function by keeping high for a few seconds. Is there a way to control dimming directly through HC238?
I think you can simulate the press by setting the pin to a high level, it will cheat the capacitance measurement and should generate a "click". But I take no responsibility for that :P
I don't think the dimmer is using an HC238, which is a decoder that takes 3 pins as input and sets one of it's outputs high, it's convenient for the relays they use but not suitable for a dimmer. They are probably using PWM for that. I have no dimmer switch here, I ordered one but I still need time to receive it...
So if you want to control a dimmer livolo switch at the moment, try to simulate touches on the buttons and the mcu on their sensor board will do the job for you.
And an unrelated question, will you be able to sell these replacement PCBs you're working on right now and when? I'm not sure I will have enough patience to solder arduinos/radios to dozens of the switches, so I'd rather buy your plug-n-play solution if the price is reasonable.
I will be able to sell them if they work fine on the long term, but that will need at least one month in the wall to be sure, then another month to order and get the fixed PCB (got some improvements to make already...).
I want to get the dimmer swith also to have a look and if possible make a PCB compatible with both normal switch and dimmer.
For the price I have no idea, either I get them done in China but I don't think there will be enough volume and it takes a lot of time to prepare (but that's an interesting process to learn ), or I make them myself which takes a lot of time and logistics to assemble, test, ship. BOM is already around 10 US$ so I don't think it could go below 20US$ for final board. That would make the final swith around 10$ more than the radio version of livolo switch, as with my pcb you can just buy the cheapest switches, without radios.
