Homeduino 433Mhz Switch turns on but not off

---

Hello,
just setup the Homeduino plugin. Problem is I can turn the Wallswitch on from Pimatic but cannot turn it off. The device is from Amazon: "Etekcity Wireless Remote Control Electrical Outlet Switch"
According to the supported devices I used Switch 8. My debug output:
When the on switch is pressed:
switch8: { systemcode: 22, programcode: ‘C3’, state: true }
When the off switch is pressed:
switch8: { systemcode: 22, programcode: ‘C3’, state: false }
Not sure why I can only turn the wall switch on from Pimatic, but when I turn it off (using on/off slider switch in the Gui) nothing happens.
Here is the Device entry:

{
“id”: “wallplug”,
“name”: “Wall Plug”,
“class”: “HomeduinoRFSwitch”,
“protocols”: [
{
“name”: “switch8”,
“options”: {
“systemcode”: 22,
“programcode”: “C3”
},
“send”: true,
“receive”: true,
“rfrepeats”: 10
}
],
“forceSend”: true
}

I played around with rfrepeats and forceSend without any success.
Thanks!
Alex

Never mind,
not sure why, but it just started working, did not change anything.
Thanks!

@alexs Maybe it is/was a RF problem, e.g. device too close or too far away from the homeduino sender, or it is a (temporary) interference problem (e.g., somebody used the vacuum cleaner nearby, radiation from other RF devices). Did you have a look at the how-to articles, https://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more in particular? You may also want to search the forum on information about de-noising the power rail and customizing the antenna.

Thanks mwittig,
yes that was the document I used to set everything up. It is working without problems now. Not sure why. The only thing I can think off is that increasing the number of repeats made a difference. Not sure anymore when exactly I changed that value.
