until now I used Mango to control just one "solar tracker" with a lot of dataPoint (more than 100) and problems concerning database growing too much.
Now I need to control 10 "solar tracker" from just one Mango gui, to achieve this I would like to use 2 Raspberry Pi 3 and a remote server, so on RPI_1 there's a Mango_1 controlling plant 1 to 5 instead on RPI_2 there's a Mango_2 controlling plant 6 to 10, I would like also to have a Mango_0 on remote server to collect data from Mango_1 and Mango_2 and to produce reports concerning all the plant of 10 "solar trackers" . I think that the main problem is how Mango_0 can collect data from Mango_1 and from Mango_2.
What do you think about this architecture? There's a way to improve it? Is it achievable?
