May you add sprinkler/Valve support?

[hugozheng2017]

I have a irrigator based on ewelink module.the model is PSF-B04-GL.It has 2 channels switch.It works fine as 2 channel switches with this plugin.But I want to work as valve/sprinkler to get the timer function.Would you tell me how to make the changes or would you release an update to support the sprinkler/valve/irrigation type?
Thank you so much for your contribution.
