MQTT multiple messages (slow)

Hi all,

Only just started with Domoticz after rocking my own PHP based domotics system for a few years. I'm slowly filling my system and have just started with MQTT and rebuilding my scripts to get everything to work with it.

I have setup RabbitMQ as a MQTT broker and have managed to get data in and out of Domoticz. So far, things are going great :)

The issue I'm having is the following:

I have a floor heating system with multiple zones, which I read through a script every 30 secs. to get all the values (temperature, setpoint, mode, valve status). This generates 4 MQTT messages per zone and I have 7 zones. This equals to 28 messages every 30 secs. The scripting is done in PHP and the script run takes less than half a second to complete (quering the heating system, generating messages and sending them to the broker). This is where the issue appears; Domoticz seems to pick up one message at a time, which means it takes around 12 seconds (!) to process all these messages from one script run. The delay I'm experiencing is so big, im having issues using thermostat setpoint devices, as when you set a setpoint it can be overriden a few seconds later by data that was still processing.

Does anybody have any idea if this is indeed caused by Domoticz only picking up a single message from the queue, instead of all available ones? Or am I just missing something here? Is it possible to set multiple messages in a single payload in a format that Domoticz understands?

I could use some insight :)

For some more information; Below is the log output of Domoticz when the script has run :

As you can see, it takes around 12 seconds to process all the messages....

I'm running Domoticz in a Docker container, on a powerful host ( 2x Xeon e5-2620v3, 64GB RAM, etc) so I doubt it's related to the hardware. The host is basically picking it's nose at the time.

Re: MQTT multiple messages (slow)

After some more testing, I had found an issue which had it sent around 112 messages instead. After correcting this, the total amount of messages is 12 and it takes around 3.5 secs. to process. A big improvement, but still to slow. The JSON API processes the exact same messages in about 300ms.

I believe this to be related to threading (or a lack thereof) on the MQTT on_message handler. Every MQTT message takes around 115ms to process, after which the next one is handled.

I'm still sticking with the JSON method, as the MQTT implementation is just to slow... :(
