I'm starting with grove sensor and node-RED with my Raspi 3.
I already installed node-RED server. I can connect actually :
- DHT11 (temp and humidity)
- Ds18b20 (temp)
- Relay
- remote to my phone
My problem is about moisture sensor, when I use "grove capacitive moisture sensor" node, my server crash and I can see an error on log :
error: command failed : python -u /home/pi/.node-red/node_modules/node-red-contrib-grove-capacitive-moisture-sensor/grove-capacity-moisture-sensor.py 4
at ChildProcess.exithandler (node:child_process:400:12)

signal: null,
cmd: 'python -u /home/pi/.node-red/node_modules/node-red-contrib-grove-capacitive-moisture-sensor/grove-capacitive-moisture-sensor.py 4'
Sensor is connected to A4 like an analog sensor. I don't understand why doesn't work. I use timestamp on input like other sensor.
My setup :
Raspi 3 grove base hat
Thanks for your return and your help.
Regards.
