expect - programmed dialogue with interactive programs
Metoden vi fra en Ubuntu sender info til vores ZenseHome PC Boks (som har ID 32010 og sidder på IP 10.0.0.110) over det lokale net.
For Ubuntu 18.04, add a global repo:
sudo add-apt-repository universe

Expect Scripts
Grundscriptet
Dette er "grundscriptet, som søger for at logge ind, agere og logge ud - jeg er ikke 100% sikker på om sleeps faktisk er nødvendige....:
Husker man ikke at lave logout eller fejler scriptet inden, da man få output fra forrige run ved næste run, og i det hele taget lidt "underligheder" 
Jeg oplever engang imellem ved brug af API at min box bare "dør" - eller at det tager længe før den vil æde en kommando igen...
#!/usr/bin/expect spawn telnet 10.0.0.110 10001 expect "'^]'." send ">>Login 32010<<\r" expect ">>Login Ok<<" sleep .5; ...... ...... ...... sleep .5; send ">>Logout<<\r" expect ">>Logout Ok<<" exit
Brug:
exp_internal 1 i koden for at se hvad der egentlig sker hele velen igennem
log_user 0 for at supresse output
log_file <filename> for at logge til en fil
List alle forbrugsregistrende devices
#!/usr/bin/expect spawn telnet 10.0.0.110 10001 expect "'^]'." send ">>Login 32010<<\r" expect ">>Login Ok<<" sleep .5; send ">>Get Devices<<\r" sleep .5; send ">>Logout<<\r" expect ">>Logout Ok<<" exit

Tænd et Device
Her tænder vi for 10604 som er en loftslampe hos mig.
#!/usr/bin/expect spawn telnet 10.0.0.110 10001 expect "'^]'." send ">>Login 32010<<\r" expect ">>Login Ok<<" sleep .5; send ">>Set 10604 1<<" sleep .5; send ">>Logout<<\r" expect ">>Logout Ok<<" exit
Sluk et device
Her slukker vi for samme:
#!/usr/bin/expect spawn telnet 10.0.0.110 10001 expect "'^]'." send ">>Login 32010<<\r" expect ">>Login Ok<<" sleep .1; send ">>Set 10604 0<<" sleep .1; send ">>Logout<<\r" expect ">>Logout Ok<<" exit
Error handling
November 2018 - Dette er en update til ovenstående, efter at have arbejde med scriptet - dette script har error handling og passende output.
#!/usr/bin/expect
log_user 0
spawn telnet 10.0.0.110 10001
expect {
"'^]'" { send ">>Login 32010<<\r"; }
"refused" { catch {exp_close}; send_user "Connection refused\n";exp_wait; exit }
"No route" { catch {exp_close}; send_user "No Route to host\n";exp_wait; exit }
"eof" { catch {exp_close}; send_user "EOF\n";exp_wait; exit }
}
sleep .1;
send ">>Set 10604 1<<";
sleep .1;
send ">>Logout<<\r";
sleep .1;
close;
send_user "Success\n";
exit
December 2018 - Dette er en toogle metode - dvs. der læses og skiftes status
#!/usr/bin/expect
