I follow the directions of creating the rollie device handler, publish it but nothing shows up on my Smartthings app.
Iām using the LevelPro Sentinel Remote tank level monitoring device for a long time without any trouble and also the support team is helpful. So you can check this device from Icon Process Controls website: https://iconprocon.com/product/sentinel-remote-tank-monitoring/
You can also contact them via phone: 905-469-9283 or email: sales@iconprocon.com.
