Sonoff SWV valve - ‘water shortage detect’ error

Hello All!

I bought a Sonoff SWV water valve for a small balcony irrigation. I my setup contains an SWV and after that a pressure regulator (2 bar) to reduce the water pressure. I am using the SWV with NSPanel Pro, the SWV runs with the newest firmware.

The SWV valve works fine, but I always get an error message in the Ewelink app - Water shortage detect. In the history I can see that there was water flow when the SWV was opened. How can I manage this alarm? What can cause this?

Thanks for helping me!


Hi! Just so you know, this alert won’t stop your SWV from working — it’s just a reminder that the flow is below 2L/min. If needed, feel free to contact support team(support@itead.cc) for help checking any possible issues.
