Re: RPi Cam Web Interface

Best way is to set in the scheduler settings for the period start to contain an md 1 command. This will be executed on start up in All Day mode. I did tried that, I put md 1 in motion start, in all day mode, save setting, reboot, but it does not seems to work. I have setup two email alert, one that...

Re: 433mhz Device unreadable

OOK is a subset of AM modulation where the only two amplitude levels are On and Off. Although it is possible to use multiple levels of amplitude to encode multiple bits per interval, I would be very surprised to see a key fob attempting to do this. I would therefore think that this is actually an OO...

Re: 433mhz Device unreadable

1) Flat battery, or

2) RX software not set up to recognise the code or modulation this sends, or

3) Broken device, or

4) Something else

So eliminate 1, then tell us how you are trying to recognise device is sending.

Re: Communication between nodemcu esp8266 and raspi3

I think what you are looking for is OTA (Over the Air) update for the firmware on the ESP8266 module. This is very easy to achieve as there is an OTA library for this. http://esp8266.github.io/Arduino/versions/2.0.0/doc/ota_updates/ota_updates.html Normally what you do is to utilise this library in ...

Re: Using two analog potentiometers to enter two digits

You can sort of simulate absolute encoding with a rotary encoder by persisting the value whenever it changes to a file and restoring from that value on start up. Rotary encoders are pretty cheap ~UKP2 and only need 2 inputs. A lot also have a push switch if that is useful.

Re: [NOOB] Light control - where to start?

With the 433MHz transmitter approach there is no need to break into anything. One is using the RX unit to capture the 433Mhz messages in order to see what they are.

Re: [NOOB] Light control - where to start?

What Shea was suggesting is the normal technique when trying to control 433MHz devices. a) Get 433MHz TX and RX modules. b) Use the RX module connected to Pi via GPIO (1 line) c) Capture activity on RX unit when buttons on remote are pressed. There is software that can help with this (e.g pigpio) d)...
