OTGW - Thermostat gets disconnected after a few seconds
Posted: Sun Aug 26, 2018 4:50 pm
Hi all,
I soldered an OTGW diy package which worked perfectly for months. After reconnecting the OTGW because of a new thermostat my home was getting heated continuously even though the thermostat was set to 19 degrees and my home temperature was 24+. When the OTGW was removed the issue was gone. Because I didn't have the time and tools to investigate I left the OTGW disconnected for a while.
Today I hooked up the OTGW to a Windows system and noticed that the thermostat is getting some 'T80190000' signals but gets disconnected automatically after a few seconds resulting in 'R00000000' messages (see attachment). When I manually reconnect the thermostat it is again connected, but only for a few seconds.
I tried to troubleshoot using webpage http://otgw.tclcode.com/debugging.html but the measurements seem correct. Then http://otgw.tclcode.com/diagnose.html, I soldered the LED's and they are blinking in order when the first diagnostic test is started. They are however blinking in the exact opposite direction as shown on the page (from right to left). Test 2 is successful until the thermostat gets automatically disconnected again, then there is no result shown anymore. I didn't do any other diagnostic tests.
Has anyone an idea about how to proceed and maybe fix this issue?
