Xbee Carrier was enough for me. I don’t need sd card or rtc.
Only the sensors I need to read are sended by wifi to a computer and just need 2 sensors on each node.
Why wifi ? Because it dont need extra usb stuff (Bee, RF, etc…) connected to the computer.
And usefull to made nodes talking together.
It’s not only temp/hum, but wished to add pressure.
and some other nodes with soil, etc…
So why not sell a bigger solar panel, considering that you already know the other is not enough ?
I’m trusted your kit, your are professional.
1- It take me some time to have the necessary money, and with this bad choice, it’s like i’ve loose my money.
2- It’s now the only solution.
3 -I’dont want to add/buy extra power, I trusted you kit and your work.
Thank you for this short and expensive experience.
BR, Pascal
