Phantom Alarm Triggers #59

Closed CodingSquirrel closed 2 years ago

CodingSquirrel commented 2 years ago

A couple days ago I pulled the latest from master and noticed that I'm now occasionally getting phantom alarm triggers. I believe the previous version I was using was around c475d71edfc0402689626619a02d215261ed30a3 since I'm sure I had the change that adjusted the HITSTAR value. Not sure which change might have caused this but I hadn't seen this issue until I updated to the most recent.

The underlying cause appears to be a corrupt message. I looked back at my previous issue (for adding vista SE) and noticed an edit where you think garbage values could be a result of wiring. I'm currently using this schematic (with a 200 ohm resistor instead of 210 and PC817 optocouplers), which is a bit different than the ground isolated one you put up. Although I'd hesitate to do any wiring changes since it's soldered now.

I managed to grab the log output the most recent time it happened.

Yes, I made a few changes on the serial library because i was seeing issues on the Vista20p. The last changes might have affected your version. Why don't you try just the file ECPSoftwareSerial.cpp from the version that worked for you. Here's the link to that version:. That will tell me if that last change is the culprit. https://github.com/Dilbert66/esphome-vistaECP/tree/c475d71edfc0402689626619a02d215261ed30a3/src/vista20SE

I doubt the resistor will be the issue since it worked before on your side. I found the Vista20p more sensitive to component values.

I'll give that a try and update what happens.

CodingSquirrel commented 2 years ago

After reverting the ECPSoftwareSerial.cpp I haven't encountered the issue.

Dilbert66 commented 2 years ago

Awesome. Tks for letting me know. I've made a small change in the latest master/dev versions to re-add one of the removed checks in the serial library. Hopefully that is the issue.
