setHeating don't work

[Cadkey]

Hello,
I've been using the API for a long time.
I want to use the setHeating function.
When I call it, I get the warning: Warning: Array to string conversion in /volume1/script/class/comapAPI.php on line 324.
I don't understand the error on this line.

And nothing changes, whether it's setHeating(true), setHeating(true,0), setHeating(false) or setHeating(false,0).

Thanks for your help.

I think there's at least this error, missing ['id']:
$url = $this->_urlRoot.'/thermal/housings/'.$this->_houses[$houseId]['id'].'/thermal-control/heating-system-state';
but it still doesn't work.

I think I've found it. The Boolean value test doesn't seem to work.
I replaced these lines:

$state = var_export($state, true);
$availValues = ['false', 'true'];
if (!in_array($state, $availValues))
{
return array('result'=>null, 'error'=>'Got wrong value, should be in '.implode(', ', $availValues));
}
if ($state == true)
{
$post = '{"state":"on"}';
}
else
{
$post = '{"state":"off"}';
}
$url = $this->_urlRoot.'/thermal/housings/'.$this->_houses[$houseId].'/thermal-control/heating-system-state';

With:

if (!is_bool($state)) return array('result'=>null, 'error'=>'Got wrong value, should be in (true, false)');
$post = ($state === true) ? '{"state":"on"}' : '{"state":"off"}';
echo 'post: '.json_encode($post)."\n";
$url = $this->_urlRoot.'/thermal/housings/'.$this->_houses[$houseId]['id'].'/thermal-control/heating-system-state';
