Hi pimatic team,
I would need your help regarding rules and variables. My pimatic system is running now for quite a while.
My main use case is the automation of a habitat in a terrarium for my Vietnamese leaf turtle.
Please find below my active rules:
I would like to discuss with you two important topics for me:
- Error reading DS18B20Sensor with hardwareId XXXXX: ENOENT: no such file or directory, open ‘/sys/bus/w1/devices/XXXX/w1_slave’
I´m getting this error sporadically and I can´t reproduce it. Sometimes the sensors (3) are working well for more than a week and sometimes this error message appears after an hour. Is this a known issue?
- I´m trying to implement a sprinkler automation but i´m struggling with the rules
Important: The sprinkler can only run for 2 minutes due to hardware limitations. After being on for 2 minutes there must be a break for 1 minute.
My goal is to read the humidity in vietnam - compare it with local humidity in the terrarium and then start the rule to reach the same humidity level.
The humidity in vietnam is read every 15 minutes. I´m using a DHT22 for local humidity in the terrarium.
I build a variable device that subtracts the variable for humidity in vietnam against the dht humidity:
Please find below my variables:
Let me know if you need anything else or if you have further questions.
