na raspberry zrobiłem monitor pieca. Super sprawa.Na Raspberry zrobiłem stronkę php pobierającą dane z Sqlite z raspberry. Potem parsuję stronkę w lua, aby otrzymać dane dla Fibaro i pokazaj je w VD.
Jak można przez lua pobrać bezpośrednio dane z Sqlite z raspberry?
To musiało by być odpowiednikiem:
<?php
class MyDB extends SQLite3
{
function __construct()
{
$this->open('/home/pi/HT3/sw/var/databases/HT3_db.sqlite');
}
}
$db = new MyDB();
$Device_id = 2000;
include 'config.inc.php';
print "<html><body>";
if(!$db){
print $db->lastErrorMsg();
} else {
$sql_table = 'heizgeraet';
print "$sql_table <br/>";
if (isset($sql_table))
{
// make a select
try {
$sql = "SELECT * FROM ".$sql_table." order by local_date_time DESC limit 1";
$results = $db->query($sql);
// retry is databse is locked
if (!$results) {
sleep(5);
$results = $db->query($sql);
}
// print results
if ($results )
{
$row =$results->fetchArray(SQLITE3_ASSOC);
if ($row)
{
foreach ($row as $key => $val)
{
++$Device_id;
if($Device_id == 2001)
{
print "$key = $Device_id = $val <br>\n";
}
