3 months ago You can try to set MQTT_SOCKET_TIMEOUT to a short time, eg 15 sec.
Add this in setup.h

#define MQTT_SOCKET_TIMEOUT 15actually, it should already be at 15 sec from the default library file. So it's weird it times-out at 30sec. Is your wifi rssi correct? (between -60 and -30)?

3 months ago Yes, fluctuates a bit, but usually it's @ -35dBm. Flaky Wifi was the first suspect, but the issue persisted even after yanking my 2 AP's off the ceiling and running a cable from my router into the boiler room and setting up a single AP there. And then i saw it disconnect at the same moment each time, so i pretty much ruled out Wifi issues. For what it's worth, i also migrated my HAOS to a new system to rule out hardware issues on the broker side. I even set up a MQTT LXC on a completely different server to rule out problems with my HAOS install. But got exceeded timeouts in all situations.

3 months ago Still think it started after the first OTA update. Maybe reflashing factory firmware back on the M5Stick and then ESPAltherma again will fix this. But, priorities. Sleep > Learn Arduino > flash. =) I'll report back here.

3 months ago Flashed factory with partition scheme No OTA and then ESPAltherma again. But unfortunately that didn't fix it, still lots of disconnects.

3 months ago Well, i think i have found the problem and if so, it's a severe case of PEBKAC...
I was looking for a way to calculate COP and i came across https://github.com/raomin/ESPAltherma#calculating-cop.
But I'm using def/Altherma(EPRA D ETV16-ETB16-ETVZ16 D series 14-16kW).h for my heatpump and it didn't have a definition for Voltage (N-phase). So as an experiment i added a definition for Voltage from another definition file. And i did get readings. But they didn't make sense so i decided not to use them in HA, but i forgot to take it out of my definition file. Today i was going through the file again and saw the voltage register still there so i deleted it. Uploaded OTA to my M5Stick and lo and behold; it is running for 3 hours now, without 1 disconnect.
So sorry for wasting your time raomin, i'll just crawl back under my rock and feel stupid. =)

3 months ago No problem @MT76, glad you fixed it. Still wondering why it caused a disconnect.... maybe a reboot...?
Running ESPAltherma on a M5StickC, connected to Mosquitto in HAOS. I'm seeing lots of short disconnects. Mosquitto log says it's due to time out:
Seemingly random, but look at the timestamp seconds: Coincides with
setup.h's FREQUENCY setting of 30000. The connection is usually re-established immediately, but Althermasensors is shown as Unavailable for a second, obviously resulting in gaps in the corresponding graphs.Mosquitto's
log_type allshows something interesting:Last three lines of successful PUBLISH:
Last three lines when a disconnect happens:
See? It's missing the last /log publish that is supposed to come after /ATTR publish. And this is the case with all disconnects. Every single one of them happens at exactly the same point in the publish process: After the publish of 'espaltherma/ATTR'.
Could this be caused by an OTA flash? I ask because the first day i got it running it did not do this. Then i discovered the OTA option and reflashed it, OTA. I'm not sure, but i think that's when i started to see this behavior. I already tried a non OTA flash but that did not help.
