V3.0.6 causes Ratgdo32 to freeze up with LiftMaster 8500 (Sec+)

[Slabonski]

Both McNasty528 and I are having the same problem (see Reddit link below). V3.0.6 does track the status of the garage door and light of our LIftMaster 8500 (Sec+) opener in both the web interface and HomeKit. As soon as we attempt to use either the web interface or the Home app to open/close the door or turn on/off the light the Ratgdo32 will execute that one command and then freeze up. The web interface will no longer load and the home app just shows either the prior state (if using web interface) or closing/opening if using Home app. The only way to get it back is to unplug it and plug it back in again. All normal door buttons and obstruction sensors work fine. McNasty528 was able to revert his back to his prior V3.0.1 to get it working again. Not seeing any crash log.

Thanks for opening the issue.

Are you able to test this while capturing logs from the serial port, or setting up a syslog server?

[Slabonski]

Yes I should be able to setup a syslog server. I saw the syslog settings in the web interface. I will try to capture the logs while it is freezing up.

Ok I think I was able to successfully capture the syslog output on my Mac using tcpdump piped to strings. These are some test captures with different scenarios described at the top of each file. Let me know if you want me to do anything specially.

Door open at start using HK to try to close.txt
Door open light on attempt control home app.txt
Door open light on turn light off web interface.txt
Repower then HK door open but did not open door first.txt
Repower then Homekit door open.txt
Repower then open door using web interface.txt

I should note that my light is a Liftmaster remote light switch 823LM which is listed as a security+ 2.0 and MyQ. It has always turned on the light when the door is opened or closed and the waits 3 mins before turning it back off. It has worked fine for many years.

So it does not look like it completely freezes up. If I repower the RATDGO32 and then open the door with either the Home app or the web interface the garage door will usually open. After it is opened, the web interface no longer responds but I do get some syslog responses from the home app. The status in the Home app never changes from opening to opened. If I hit it again it just says closed. I can repeat this over and over and I will get syslog responses but the door stays open. Same with the light. As you can see from the other logs it responds similarly (web interface freezes some responses from Home app) when the door starts open but the door never closes.

Door closed light off use web interface to open then try Home app.txt
Door closed light off use Home app to open then try to close.txt

Thanks for the logs. In do see quite a few that are of concern which gives clues for me to look at.

Could you reduce the time-to-close delay to zero please… just to remove one variable, some of the errors are coming up in that code path.

I can do that but I will not be available to do more testing until next weekend.
