Kauj Ruam 4: Tswj Koj Tus Menyuam Los Ntawm Lub Vev Xaib

Tam sim no, qhov no yog kauj ruam kawg rau peb txoj haujlwm.

1. tam sim no qhib koj VNC chaw taws teeb duab sib txuas ntawm raspberry pi los ntawm kev nkag mus rau tus IP chaw rau koj Pi
2. tam sim no qhib lub davhlau ya nyob twg thiab pib ntaus cov lus txib hauv qab no
3. ntawm no coj yog lub ntsiab lus thiab "0" yog them nyiaj
4. hloov tus IP chaw nyob hauv kev hais kom ua nrog koj Rpi IP chaw nyob
5. Thiab es tsis txhob "0" sau "1" uas yuav qhib rau koj txuas ntawm lub sonoff wifi hloov.

mosquitto_pub -h 192.168.0.104 -t coj -m "0"

Cov lus qhia saum toj no yuav tua koj lub relay.

mosquitto_pub -h 192.168.0.104 -t coj -m "1"

Cov lus qhia no yuav tig rau koj qhov txuas.

Tam sim no koj tau ua tiav nrog kev tswj hwm koj li sonoff los ntawm Rpi davhlau ya nyob twg.

koj tuaj yeem tshawb xyuas los ntawm kev txuas lub sonoff wifi hloov mus rau lwm lub network wifi sib txawv thiab raspberry pi mus rau kev sib txuas wifi sib txawv. Koj yuav tsum muaj peev xwm tswj hwm kev xa tawm los ntawm txhua qhov chaw hauv ntiaj teb.

Tam sim no txawm tias ntxiv koj xav sim ON/OFF ntawm koj sonoff txiav kuv tau sau ib tsab ntawv nab nab

uas xa "1" ua ntej thiab tom qab 6 vib nas this nws xa "0" thiab cov txheej txheem no rov ua dua hauv lub voj.

ntshuam paho.mqtt.publish li luam tawm lub sijhawm

Thaum Muaj Tseeb:

print ("Xa 1 …") luam tawm.single ("ledStatus", "1", hostname = "Koj tus broker IP") time.sleep (6) print ("Sending 0 …") publish.single ("ledStatus", "0", hostname = "Koj tus broker IP") time.sleep (3)

Cov cai saum toj no yooj yim tig rau thiab tawm ntawm qhov txuas ntawm lub sonoff wifi relay hloov.

tsis txhob hnov qab hloov koj li RaspberryPi tus IP chaw nyob hauv tus nab npawb nab npawb saum toj no. tam sim no khiav cov ntawv no los ntawm txhaj rau qhov xaiv khiav module thiab koj yuav tsum pom ntawm lub plhaub

xa "1"..

xa "0"..

xa "1".. tej yam zoo li no.

Nov yog nws rau Cov Lus Qhia no. ntsib koj tom ntej nrog tus tshiab.

Nyob zoo !!!!

thiab tsis txhob hnov qab ua raws thiab qhia cov lus qhia no thiab sim nws ntawm koj tus kheej!
