Losing connection with boiler #53

Closed shaggee closed 5 months ago

shaggee commented 7 months ago

Im using 1.4.0-rc.15 on Wemos D1 mini with Termet Ecocondens 25 Integra II boiler. The connection works well but after couple hours, the connection with boiler is lost.

Manually restart OTGateway - no results Manually power cycle OTGateway - no results Manually power cycle boiler - connection established again

How can I check the connection logs? Any advice to resolve this problem?

Connect via telnet and save logs when the problem occurs. This may be due to the boiler settings or the wiring. What is the length of the wire? What wire is used? Are there power wires near the opentherm wire?

The wire is arround 30cm length. Yes the are power cables near opentherm wire. I will move the board and wires and test it again.

Hi @shaggee Did you find the problem?

Hi @shaggee Did you find the problem?

What I did:

  1. Shortened the cable to 15cm. The cable is a simple 2x1,5mm2 speaker cable.
  2. Moved the Wemos D1 and OT adapter away from electric cables

After this upgrades, im still losing the connection

Im recording the logs since yesterday 14:00 . So far the connection is stable. Strange.

Strange. I saved the telnet logs for 4 days without any connection lose. Today I turned off logging and tadam. After 10 hours connection losed:

Seems I need to set up the server for 24/7 telnet logging to get it 100% work.

I tried. It doesnt help

Laxilef commented 6 months ago

I think it is necessary to save the log at the moment of connection loss. Perhaps sending some request breaks the openterm on the boiler.

shaggee commented 6 months ago

Okay give me one week to record the logs 24/7.

shaggee commented 6 months ago

Problem solved. Replaced Wemos D1 mini to ESP32 D1 mini and there are no connection issues. It may be D1 mini firmware/hardware problem.
