Saswell irrigation controller is not compatible to Fibaro Hc3. It connects but silence right after. Be careful some stores  claim that is compatible to Hc3 but it’s not.  I removed the link of the store claimed that irrigation controller was compatible to HC3 as the “gentlemen” had the sensitivity to remove the HC3 compatibility logo of the device’s link.    probaby there are multiple firmware editions out on market (mine doesn’t work) I ll get a Tuya hub in order to get it to
