How to test email setting for Alerts?
Hello, I am using the standard OTGW version with firmware 5.4 (PIC16F88) and web otmonitor v6.1. Since Google's support for less secure applications has ended, I have set new parameters for the SMTP server (that I use by default for mail communication and for notifications form other systems). After...

Re: QAA73.110 showing incorrect values when otgw connected
Hi Schelte, I've managed to test QAA73.110 and OTGW today. As you can see from the log below my OTGW was set to Gateway mode at 10:14:01, then I entered OEM's mode on QAA73 (in this mode I can change some LMU64 (boiler) values) at 10:14:45 and since that time I see only some strange values in the lo...

Re: using ds18b20 for return water temp
When I realized that only 1 LED is working I simply adjusted Room temperature +2 degrees, waited until boiler started to heat, then checked status page a saw Flame = ON and LED A was OFF. I was testing Monitor and Gateway mode with QAA73 so it's possible that device was in Gateway mode. I missed inf...

Re: using ds18b20 for return water temp
As for LED's I can confirm that my setting (below) is working since long time ago without any change (now on 5.0 firmware). (I don't have DS18B20 connected): ... Actually I should recall this statement. It looks like LEDs are somehow broken. I'm using Cyril's fork of OTGW (https://www.domoticaforum...

I will post logs for both cases during a weekend as it's not possible to physically get there now (covid rules).

Re: QAA73.110 showing incorrect values when otgw connected
GW=0 --> value 506 (TvSmin) is set to 20.0 C GW=1 --> value 506 (TvSmin) is set to 404.0 C Thank you for confirming this. I believe it's caused by setting QAA73 to "programming" mode and OTGW somehow interfering communication between QAA and LMU. It's only cosmetic defect found and does n...

Re: OTGW firmware 5.0
OK. Thank you for clarification. You are right, I did not realize that I should upgrade to 5.0 firmware. I'm receiving Github notification when new OTMonitor is released and forgot to check http://otgw.tclcode.com/firmware.html website if new firmware is available too. Now PR=D returning PR: D=O. an...

Re: OTGW firmware 5.0
Thank you very much for this! So far working like a charm. I'm not using DS18B20 as my boiler has external sensor attached, but testing command PR=D returns PR: BV. Is "BV" an abbreviation for not available or not connected? Is O or R used for any calculation in OTMonitor or it's replacing...

Re: QAA73.110 showing incorrect values when otgw connected
Just a quick update on this strange behavior - it looks to me that it's caused by OTGW setting GW=1 (gateway mode). I've made several tests with 2 different OTGW devices and found line 506 TvSmin with incorrect value 404 C only when OTGW in gateway mode. Switching back to GW=0 solved this issue. I b...

QAA73.110 showing incorrect values when otgw connected
Hi All, I'm using latest OpenTherm Gateway (4.2.8.2) + OpenTherm Monitor 4.5 with Geminox THRi 2-17 M75V (Siemens LMU64) and QAA73.100 controller. As my boiler does not support Remote override room setpoint functionality, I'm using OTMonitor as MQTT client which sending data to Home Assistant. Some ...
