hello , sorry, if answer basic or in wrong forum.
programmer, knowledge of linux shell, virtually no experience soldering (i have access solderer).
put temperature sensor (like 1 - "ds18b20", doesn't matter much, need whole number (integer) precision) in rooms in house, near ceiling , connect them pi (raspberry pi 3 b), can read value of sensors python script. found tutorials, have questions:
a) remote room measure 30m of cable away rpi. problem, if use "tree smaller wires in one" wire, connect sensor , proceed in tutorial?
(wire =https://images.duckduckgo.com/iu/?u=htt ... 05.jpg&f=1)
b) tutorials multiple sensors show, example, 3 sensors @ 1 time. like, ideally, as 10 sensors (i need 4, if it's , issue, don't need more that). this, however, possible?
moment can read sensor value shell (from filesystem) i'm okay, need part. thank reading

if go onewire sensors can put quite few of them on single line. here great writeup on long distance onewire networks , sensors:

if find far away, might consider emonth (https://openenergymonitor.org/emon/modules/emonth) low cost wireless transmitter can couple emoncms tracking , monitoring. can write of data mysql can query python.
