Hi all !
I have a project that I would like to test and realize using mydevices. Please, I would like to know if you can help me by selecting the most simple / cost effective hardware to make the following set-up.
The project consist of the installation of:
- one main station connected to internet with main power supply 220Vac
- several devices powered with batteries with on each device: 1 x relay output and 1 x input for counting pulse from reedswitch
The main station should be connected to a simple database. The main station has also several DI (at minimum 8 and should be expendable). The following function will be used:
- When DI n°1 is activated => close relay of device n°1
- When pulse are counted on a Lora devices => send the amount of pulse back to the station and record them in the database with time stamps
Therefore, If anyone of you can help me just to select which equipment we should buy to make the first prototype ?
For the mainstation, I was thinking of a RPI with a piface but what abouth the lora on the RPI ?
Many thanks to all for your help
Keep up the good work !
