@tomkxy I'm using this one: http://hu.farnell.com/multicomp/mcvz1206m050agt/varistor-multilayer-4vac-0402/dp/2462756

Good job!

@barduino Thx, good job!

Use V_LEVEL

MyMessage msgSmoke(CHILD_ID_SMOKE, V_LEVEL); 

Good job. I found a bug. I can't select the link in the BOM list. Google Chrome v47

Hi,

I now received PCBs from DirtyPCB. I'm searching components (but not from China sellers).
Can I use this varistor on the AC side?: http://uk.farnell.com/multicomp/mcsr391k10ds/varistor-60j-250vrms/dp/1856880
And on the DC side?: http://uk.farnell.com/multicomp/mcvz1206m050agt/varistor-multilayer-4vac-0402/dp/2462756

Thanks in advance!

@scalz: thank you for you calculation. It's interesting. I will measure it if I receive the MCP16251.

@the-cosmic-gate Nothing special. I made a big sketch, which contains 7-8 sensors (DHT, Si7021, MQ-2/9, PIR, Door magnet, Light, battery) reading code because I would like to upload the same sketch to all nodes and configurate it on controller side, which sensors is on the node and need to read.
But currently I reached the limit with I2C includes, so I need to think over this solution.

@ericvdb Sorry, I read somethingh wrong
