Problem with MMM-ValuesByNotification and MMM-CommandToNotification

[wishmaster270]

@Jimmy1502
The script uses GPIO 4 in default but accepts any GPIO number as first argument.
At least GPIO 25 has no double function on raspberries and should work.

You can call the script directly in the shell and check the output for debug purposes.
And make sure to check the comments in the first lines of the script if you need to. install any dependencies.

Edit: Looks like you use GPIO 12 in your config which should work, too

@wishmaster270 this advice really helped. I tried using the script and saw, that the adafruit library was outdated. Updated it and now it kinda works. The script and my sensor is working. I get good reasonable values if i use the script manually. But the Mirror is kinda weird.
When i measured the temperature manually it said sth. around 21°C but ValuesByNotification outputs: “NaN” so Not a Number?
Humidity is kinda working. The majority of the time it is giving me a value of 47%rH but sometimes after the module is blinking (I think it is refreshing), it suddenly changes to 0.00%rH. But the next blink changes it back to a real value.

Thx for your help

@wishmaster270 Oh i could sworn i just submitted sth. but i cant see it in the notifications…

Well for a second time:

It kinda works now. I tried using the script as u said manually and the dependencies (adafruit library) wasnt up to date. I got reasonable outputs.
But the ValuesByNotification Module isnt working as intended. I Just get a “NaN” (“not a number”?) for the temperature. The Humidity is kinda working giving me a reasonable output. But sometimes after a blink (i think a refresh?), the value changes to “0.00%rH” but after another one it is good again.

@Jimmy1502 all.posts for users with reputation below 2 are reviewed by me before posting.

so… sometimes you have to wait til i get back to the forum

you can see your pendkngmpodts.in tye pending queue under your user icon top right

@sdetweil i have seen thath. But usually it shows me in the notifications that its not approved yet. But i couldnt find it. Thats why i was confused.

@Jimmy1502 I have seen the pending g list be empty when it’s not. maybe your side has the same problem

[wishmaster270]

@Jimmy1502 I think the problem with the temperature is caused by the json path. The script outputs temperature_c and temperature_f but the json path causes the module to search for temperature only.

The problem with the humidity may be caused by the interval you query the sponsor values. 10 seconds is very short for the dht sensor. Maybe you can try a bigger interval.

@wishmaster270 I can see the temps now. I increased the UpdateInterval in both ValuesByNotification and CommandToNotification and made them different. But i still got the “0.00” for both temperature and humidity. But i dont think it should be the UpdateInterval. Cause when i tested the DHT22 with a Microcontroller i was able to get values every second.

@Jimmy1502 As the reuseCount is set to 100 the wrong value need to be caused by the script sending them.
It only sends 0.0 if a error occurs.

You may remove the except block in the script and fire it very quickly on the shell to see what causes the error.

Hi! Ive been busy so i couldnt work on it. I removed the except block with five “#” for each line to make it a comment. And i get the following error. The line 32 has a syntax error “invalid syntax”. It is the print function printing json.dumps(result))
