More devices IN

I've completed to code to add more devices, so now the module as common code can:

• update from OTA server if the version on server is bigger the its own version of code
• get the data from AUTH server (topics, type, MQTT server etc, credentials)
• get the time from NTP server
• log data to an external server
• log debug data to a DEBUG server
• do  CRON tasks on GPIO pins based on schedule received from Android App
• send status and its state to Android app.

All these features are part of the common code that will run an all my modules.
Now sky is the limit on what each module can do : 

• temperature,
• humidity, 
• noise, 
• presence,
• gas detection, 
• acceleration, 
• vibration, 
• measuring power consumption, 
• controlling blinds, 
• garage door, 
• boiler, 
• irrigation controller, 
• fish tank, 
• motors, 
• air conditioning or a thermostat etc
• coffee machines
• washing machines
• fridge
• remote control substitute for TV, Satellite dish, Cable TV or any other IR
• power sockets
• exterior lights
• interior lights
• power sockets
• air quality

And the beauty is that I am not limited by the WiFi, the same things I can do with my new LoRa modules.

The all power will be at your finger tips.

 Obs: Later I'll try to add some Artificial Intelligence (AI) to my system, because the IoT without AI  is pretty  much limited on manually or semi automatic control.

Android application Homy

The new Android application that is connecting with my broker over web sockets is having now new features:

1. Auto-discovery. Each time the application is started, all devices are sending their status. Here there are 6 IoT devices discovered:

• two plugs
• two irritool ( one is in production for more then one month, and the other is for debugging and simulation ( NASA style :-)  )
• two (dth - digital temperature and humidity sensors. They are mount on each irritool)

6 devices dicovered

2. Devices are presented on categories, based on the incoming  data from them. 

At  this stage the name is based on the unique device id and its type.

Plug devices discovered

3. Device detail. All the information about device is presented in here:

-device id

-ip address

-network type (B/G/N)

-up time ( if is configured to be transmitted)

and I am able to control the device ( like in plug/irritool case) or see the data for sensors.

Device detail - PLUG

Device detail - IRRITOOL 

Device detail - Sensor DTH

Looks ugly and hard to remember that the ESP_00A08478 is the name for irrigation controller so I've added the new option to rename the device name with whatever you want. This aliasing is persistent so every time I reopen the application, the mapping between device id and device alias is the same.

Here is a renamed plug:

Plug renamed 

Other feature is 7 day weather report for my location (need more work in presenting the data).

weather report next 7 days

I can declare now the application to be in alpha stage ....

4.Other option I have in the Menu:

Debug will be to see the messages received from broker.

There are a lot of picture in this post, but a picture is 1000 words.

Post man #4

To extend the range ( which seems to be fine for my project at this time) I've ordered some 

19 cm mini PCI U.FL to RP-SMA WiFi Antenna Cable. My plan was to reuse the antenna from NRF240L01P modules but I didn't checked the connectors. 

SMA U.FL wifi antenna cable and antenna from NRF24L01

Murphy's law is applicable also in this case, so as you can guess they don't match. So the new antennas are on their way also.

I've received also the BMP180 sensors ( replace the old BMP085 version). 

• Pressure sensing range: 300-1100 hPa (9000m to -500m above sea level)
• Up to 0.03hPa / 0.25m resolution
• -40 to +85°C operational range, +-2°C temperature accuracy
• This board/chip uses I2C 7-bit address 0x77

The sensor and its board is very small, which is great. 

So I have temperature and humidity from DHT22, pressure from BMP180, I can now predict the weather for my irrigation platform.
