I just recieved my small CNC mill (that will primarily be used for Laser engraving) and want to try milling some PCB. Anyone has a suggestion an a useful PCB that is single sided and can be used for something fun wihtin MySensors range (or not )

I don't know, but according to https://forum.mysensors.org/user/ceech last time online in this forum was September 2017.
His eBay shop is empty.
Not a good sign...
@orhanyor A piece of aluminium fixed my problem (Well 99% better). The sensors I have report in every 2 minutes and I get an error alert if they do not. Without the sheet in place it is just non stop communication errors. there is a thread I posted all about it.
@benhub do you have the code the links seem dead? Ive been trying to get 2 temp/hum sensors (DHT22) working in domoticz for quite a while now with no luck. The temp/hum data in domotcz keeps swapping around from one sensor to the other and i cant work out why.
@mirodin said in How to power my sensors in a rental?:
using normally closed reed switches
You can "convert" those by reverting the orientation of the magnet on your door, then adding another magnet (weaker or further away) inside the node enclosure to keep the reed switch closed when you open the door. When the door is closed the reversed magnet on the door will open the reed switch.
To do even better you can use :
reed switches with 3 leads that work as both normally opened and normally closed switches, and wire them to the 2 interrupt pins. I used that on my first nodes and managed to get reeeeaaaally long battery life on a simple CR2032. When door status changes the node is woken up then you set pin low and current could run only a very short time, you send the message with new status then you activate the other interrupt pin and go back to sleep https://www.aliexpress.com/item/33028519094.html
if you're not afraid with SMD there are some ultra low power hall switches, using less than 1uA of current like the DRV5032.
