Hello, yes, I tried it, but the server is not responding: $fp = stream_socket_client("tcp://".$serverIp.":".$serverPort, $errno, $errstr, 30); $msg = pack("n*", 0xE3DC, 0x0100, 0x1159, 0x7B53, 0x0000, 0x0000, 0x0000, 0x0000, 0x0E00, 0x2000, 0x0006, 0x0000, 0x0012, 0x0000, 0x0100, 0x0000); $msg .= pack("N", crc32($msg)); if (!$fp) { echo "$errstr ($errno)<br />\n"; } else { fwrite($fp, $msg); while (!feof($fp)) { echo fgets($fp, 1024); } fclose($fp); } I'm receiving a timeout after 30 seconds.

Hello, thank you! I found a Cpp implementation for this protocol, but I'd like to have it in PHP, because my home automation is based on PHP. What is the easiest way to "convert" a Cpp implementation to PHP?

Hello, is it possible to implement a RSCP (Remote-Storage-Control-Protocol) communication for a PV-battery with PHP? I'm experienced with PHP, but I have never implemented a socket communication with PHP... How do I create a frame fulfilling the length constraints (see attached image)? For example, what do I have to do to send the following frame: Frame: 0xE3 0xDC 0x01 0x00 0x11 0x59 0x7B 0x53 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x0E 0x00 0x20 0x00 0x00 0x06 0x00 0x00 0x00 0x12 0x00 0x00 0x01 0x00 0x00 0x00 + CRC32 Checksum Best regards, Brovning
