BlueIris and MQTT

Hi alphatech, PM sent

Hi Michael,
For some reason it is not capturing the license plate and I'm not sure why. What am I doing wrong?

Thanks

Are you asking why HS shows device value of 0 while Association table payload shows a text string? If so, then click on 4951 button and change the Control/Stautus UI from Number to Text.

Thank you Michael

Ok, so I finally installed the license plate Camera I bought during the Pandemic and hooked it up to Blue Iris... I am with Code Project and I am posting my MQTT messages with Blue Iris and I can see them with Mosquitto Sub just fine.. It seems to do a great job of detection.

BlueIris/LPR/Plate {"trigger":"ON", "PLATE":"872SX7", "MEMO":"DayPlate:98%" }
BlueIris/LPR/Plate {"trigger":"OFF", "PLATE":"872SX7","MEMO":"DayPlate:98%" }

I am trying to read this topic into McsMQTT and it sees the Topic, but it doesn't appear to see any payload.

Did I do something wrong here? Usually, I click on that A and I can add a device?!

You would see the plate number on that screen if you had it right. My BI5 settings look like this:


Where the full payload is: { "plate":"&PLATE", "AlertImg":"&ALERT_JPEG", "AlertImgPath":"&ALERT_PATH", "Alert_AI":"&MEMO", "Date":"%d-%m-%Y %H:%M:%S","Camera":"&CAM"}

mcsMQTT would look like this if the plate number was ABC123:


And yes, you can use the associate button.

BlueIris/LPR/Plate {"trigger":"ON", "PLATE":"872SX7", "MEMO":"DayPlate:98%" }

I just sent this one via MQTT Explorer and it came through to mcsMQTT as the following.


Seems the issue is with BI sending the mqtt alert? Have you used MQTT Explorer or similar to verify what's being sent?

Yes. I used Mosquitto_sub and I used Mosquitto Explorer. It looks good in both places. I tried just making the topic "LPRCamera" without any slashes...

I am going to copy and paste your exact MQTT message.

I am wondering if I accidently clicked a MQTT setting to disable discoveries or something-- but mine says it is clearly on...

Well, hot diggity dog. I copied your payload (my topic is now "StreetCamera") and waited for a car to drive up the street...




I was able to add all of the devices normally....



Here are my settings now. I am not sure why it wasn't registering it before, especially since it worked for Wade?!?!

My screens look slightly different that others... maybe I installed the latest?




Thanks!

Are you able to see the @ALERT_JPEG in Homeseer at all? I tried setting that to JPG in McsMQTT and didn't have any luck.....

[Traction Tim]

Excellent ! This is all undocumented, so I built that payload with the help of alphatech. It does make sense looking at the BI5 variables in the help file, but no, I didn't get to see a jpg. Some experimentaion is required

[Traction Tim]

The secret sauce from BI5 are those "&" variables shown in the help file here. For example "plate":"&PLATE" will tell Homeseer what BI5 has for &PLATE, but "plate":"872SX7" will give you 872SX7 every time. Good for testing, and it does mean that you can force the output you want.

If you check DAT files for other cameras, you will also find the license-plate custom model is active on all of them. I stop this with alpr:0 on all other cameras like this:

Are you able to get this thing to trigger if you see a plate? I am getting pretty much all of dayplates. It show up in the device status, but not the value. I don't see any triggers for status-- maybe under easy trigger?

I ordered a LED light for the night time. I got it working ok but it definitely needs some more UV.

[Traction Tim]

Yes, it works here. I can't remember if I had to change the mcsMQTT device properties to "Text" or something, but I can see the licence plate numbers and letters text in Homeseer.
