Blockly and soil moisture sensor
Posted: Monday 03 February 2020 18:44
Hi folks,
I'm trying to automate my little chilli pot garden. I wanted to measure soil moisture. So I've managed to connect capacitive soil moisture sensor to esp board and send the data to domoticz which runs on RPi2B+. This results in a reading on a sensor "abc":
The problem is that when I try to use this value in blockly to start the water pump:
I get the error message in log:
2020-02-03 18:40:16.337 Error: EventSystem: Lua script error (Blockly), Name: Script #2_1 => [string "result = 0; weekday = os.date('*t')['wday']; ..."]:1: attempt to index a nil value (global 'utilitydevice')
What seems to the issue here? I have tried to find an answer on these forums to get this thing to work but I could not find any solution. Is this due to the value being of different type?
