@berkseo nice! What did you use for the capacitive sensor? MPR121?

@lange60 you need a gateway that the Vera connects to. I use the Ethernet gateway with NRF radios. So, Vera connects via IP/Ethernet and the gateway connects to the sensors wirelessly via NRF radios. Most of my devices (including the gateway) use Arduino Pro Minis.

@Kai-Bepperling I have been wanting to make something like this for years. I keep getting sidetracked so I have never completed anything. I am excited to try this method at some point. I have a few rooms where this would work much better than the motion sensors I have now. Thank you for posting this.

Maybe you need to update the bootloader and/or fuses? Maybe it has a brownout setting of 4.3V?

@vladimir Yes, you could probably use an optocoupler to read the LEDs without taking too much power from them.

@vladimir I have very little time these days so I won't be able to help in detail but if you want to use my method you will need to open your kettle and see what type of buttons they are. They will be connected to ground or power. When you know that you can choose the correct mosfet and start testing. Take a look at my wiring diagram to see what I've done.

@mortenvinding cool! I looked at a couple of code "sniffers" when I did this but none of them worked. Good to hear progress has been made on that. Should save quite a bit of time.

@lis610 Awesome! Congratulations and great job for not giving up. That was a lot to tackle for a first project! Nice enclosure to house everything. Looks way cleaner than mine

@lis610 It should work at 8MHz. Have you double checked the wiring? Did you try with the default sketch in the DHT library? What are the debug messages saying?

@lis610 Great news! I echo what @hard-shovel said. I try to supply my 5v sensors with 5v power from a regulator (with the appropriate capacitors) instead of my Arduino.
