To provide a large enough pulse to drive the ceramic transducer , you need a lot of energy, so they pump up the 5v with an inductor/transformer to provide a high voltage pulse. This is 60v or more… The more Energy you produce the farther the pulse will travel…. Everything thing else on the board run at 3.3 to 5V. Add a large Capacitor of 100 µF are so between the 5v and ground on the device, this may clean up your problem.. Some CPU modules just can’t supply enough current quick enough that’s needed when the pulse is triggered. These are very inexpensive device, we’re luck to see them work at 1/2 the spec range.

Be aware that sensor need to have 20 consecutive failed transmissions before starting to look for a new relaying node.

I liked domoticz (was very easy to set up and use). Together with dzVents scripting wasn't that difficult either. But I also had some problem with it lately, so I was actually thinking about switching to openhab (2).

My current roller roller Shutter switch are two pushed buttons up and down. No stop button. When release the push button up or down, the shutter will stop. WIll it be compatible with this board or will i have to change the buttons ?
