Let's Control It

I have not tried the 64*128, maybe they are different. The 12864 LCD doesn't work with ESPEasy, it works over the SPI bus and I used the U8Glib with Arduino to let it work. http://www.aliexpress.com/item/128-64-DOTS-LCD-module-5V-blue-screen-12864-LCD-with-backlight-ST7920-Parallel-port-LCD12864/32...

I solved my problem

Under Optional Settings I gave the field : 'Value Name 1' the name Vcc

For the Oled I used this line: Vcc [Vcc#Vcc} and it magically worked.

costo

show me the way you printed System Info on a LCD/OLED, for me it does not work, I get nothing on the display.

I tried:
Vcc [System Info#Input VCC] and
Vcc [System Info#Vcc]

The display only shows 'Vcc' and no value

costo

Did you get some system-info values on your lcd/oled display ?

costo

I know of these variables: IP, UpTime, SysName, and SysTime Shown on a LCD/Oled like this: %ip%, %uptime%, %sysname% and , %systime%. In the Task Setting "System Info" there are are these varibles: Uptime, Free Ram, Wifi RSSI, Input VCC. How values from a device can be displayed on a LCD/O...

Don't forget that a level converter only transforms the voltage level. All the current that flows through the relais will flow out or into the GPIO of the ESP. Max current a GPIO can safely handle is 12mA note#. So if your 5V relais has a coil-resistance of 500 ohm the current will be 5/500=0,01A or...

my personal opinion on this: I do not think this is the way to go with RFLink. I2C needs the wire library and every sensor needs it,s own library. ATmega is a relative slow processor , it needs to decode RF signals , communicate with a host over USB and eventually communicate with the wireless NRF m...

Last year I bought some Lcd's, a 4x20 character display and a 64*128 graphic display. Both are white dots/character with a blueish backlight and both need the 5 volt to have enough contrast. On 4.5 volt they have already not enough contrast.

Maybe I should try a yellow or green lcd

@ hamster

you do not need to build new boards for using ota on ESP_01.
New Esp 01 sold today often/usually have 4mbyte flash on board.

costo

either connect your led with series resistor to Vcc or to ground.

costo

I haven't done this. Buying a new ESPboard is cheaper than buying a 32mbit flash chip. It can be financially interested to do if you own a lot of old ESP boards with 512kByte memory chips that you like to upgrade. I have only a few of them and do not own a hot air iron so I just bought a new ESP12E....

costo

Works like a charm. By the way, both the LCD module and I2C to LCD module works well on 3.3V. My experience was that a 5V LCD module does not work on 3.3V, it needs 5V for the contrast setting. (Unless you have a 3.3V LCD module which has extra components on board to generate the contrast voltage.)...

It is just by design.
Some ESP modules have the blue Led connected to GPIO2.

So the led will turn on when GPIO2 is made 'LOW' which explains what you see.

costo

On the sonoff GPIO12 is the relais and GPIO13 is a green LED that will light when the relais is activated. GPIO12 does the switching via a FET switch, so when GPIO12 is 'high' the relais is 'ON'. When GPIO13 is 'low' the LED is 'ON'. See this page for the schematis of the sonoff: http://wiki.iteadst...

Any ideas about that problem ?

It is not a problem, it is a feature

It is a known fact that there can be a substantial delay over WiFi , you have to live with it.
I have it too when I use rules, a few seconds is normal.

and using pl2303hx usr-ttl for communication.

Does your pl2303hx support 3.3V RX-TX ?
Do you see " /dev/ttyUSB1 " or something similar as port device in the IDE and did you activate it ?

edit: assumed you can use Arduino IDE

costo

Nah, don't think so. I have plenty of capacitors there. Seems that the analog pin is still affected by external voltage. After removing the resistors that made up a voltage divider, the problem was gone. Thanks for thinking with me. I tested this feature with a NodeMCU board which has a onboard vol...

@ sieuhoatinh There can be many reasons why you cannot connect to your network. Some I can think of: a). Your network SSID or passwordkey cannot contain spaces or special characters. b). Before flashing R78 on the ESP you had a later beta version flashed to it. Newer versions use a different form of...

To my knowledge, there is no command to read the state of an output in ESPEasy.

It does not need to be Domoticz to control your sonoff relais.
As long as your controlling server can fire the command: "IPofYourESPEasy/control?cmd=event,switchon" or switchoff it will work

I know I am late to the party, but I'm about to convert some sonoff's to run ESP Easy and this feature would be excellent to use. Did it ever get added and if so which version do I need?

I have VCC read activated on several ESPs 12 and get weird readings, varying from 1.71 to 2.96 volts. Am I missing something?

You should download the stable version R78 , the link is at the bottom of this page: http://www.esp8266.nu/index.php/Main_Page
In the zipfile you will find the libraries you need.
After adding these libraries you can compile also the newer versions up to R107

costo

I believe it is a memory limitation of RFXcom. Adding new devices/protocols is not possible in older RFXcom because memory is full. So you have to load a later firmware to use the latest devices. I assume you sacrifice some older/extinct devices/protocols by doing so. RFLink for the moment has enoug...

Installation into Domoticz was not as I expected: I was looking for a "relay" device in EasyESP, but no such thing is there. I got it working by creating a dummy device in Domoticz, and send the on/off commands directly to the IP address of the device as "On/Off actions". It wor...

OK, I got through step 1 (soldered a 4-pin male header). And found out that the inner pin is vcc, outer pin is gnd. The two pins in between must be TXD/RXD, not sure which is which.

Do i need to connect all the wires... GND VCC and the 2 hardware pins? Sure, if you talk about I2C sensors. Ground is always common for all sensors/circuits. Vcc is needed because your sensor needs power. SCL and SDA are needed for the communication. Do not forget that there must be somewhere on yo...

you are right, it works perfect as long as you stick to a limited number of pre defined types. Besides, for every device you are required to create a hardware device.

You use address 0x38. Maybe you should try address 0x37 by making the 3 address pins 'HIGH'. If I look inside the WebServer.ino there are 3 addresses available for PCF8574, these are 0x20, 0x27 and 0x3F. I am not 100% sure but it looks like ESPEasy will not work with other addresses than these 3 men...

I added an additional 100n capacitor between VCC and GND and a 15n capacitor between RST and GND.

You need to add a good capacitor of about 10 uF, with low self indu...

Most cheap UV modules generate a analog output voltage that is proportional to the amount of UV so this is perfectly compatible with ESPEasy.

That is a typical Domoticz question and not ESPEasy dependent.

I used the type: 'Custom Sensor' that gives me a tile in the Utility page where the total count is shown or the amount of FreeRam is shown.

If you have enough 10k in stock you can use 2 * 10k in parrallel instead of 4k7.
