Re: PIR motion sensor tutorial false positives

Those sensors are susceptible to wifi transmissions. Mine triggered a few times per minute.
Do you still get false triggering if you turn wifi off or move the sensor about 30cm away from the pi?

Re: Cannot Connect to Motion Server on Other Devices

Can you ping it?
From command prompt (windows or Linux) do
ping 192.168.x.y
Or whatever your pi address is.
This will check whether your router will allow WiFi to WiFi communication.

Re: Is my cell phone charger good enough to supply power to my raspberry pi

I see messages like this so often!
Do you think we need a specific sticky 'phone chargers do not work'.
Not only will the voltage sag as load increases, but I fear won't some be regulated and will give over-voltage at times, with damaging consequences.

Re: Potato Weather Station

You will have to provide power of some sort if only to power the sensors! In general sensor output is low power which would not transmit easily over the distances you mention.
You could consider power over Ethernet so you can place the pi close to the sensors.

In the absence of other responses I'll jump in here, but it's an indirect answer. You could try the program with and without the bounce and see the difference.

With that setup you appear to have two devices offering DHCP services. Switch the DHCP server in the router off and rely on the Android phone to do that.
