Hi,
it seems that itead becomes our favorite producer of esp-based items.
I just got an advertsiment from sonoff for this one: https://www.itead.cc/sonoff-4ch.html
Is has the ESP8285, documentation says, this is the 8266 with flash onchip. So, can it be used for espeasy?

ambassadoro

Just found out 2 very cheap units that looks perfect candidates for ESPEasy: 4 relays 10$ --> https://www.aliexpress.com/item/LinkNode-R4-Arduino-compatible-WiFi-relay-controller/32704022155.html 8 relays 15$ --> https://www.aliexpress.com/item/LinkNode-R8-Arduino-compatible-WiFi-relay-controller/3...

Some weeks ago, I already mentioned this device. The frequency is for espeasy a kind of pulse-count I guessed, but how many pulses can espeasy afford?

ambassadoro

Soon, itead comes out with a new sonoff-device with power meter . ESPeasy should run on it, but will it be possible to read out the data from that HLW8012 chip thats on that device. Unfortunately, this chip seems to be a very chinese one, I haven't found much information about it. Update: I found so...

Looks interesting, can it be accessed by MQTT, too? Would be more sophisticated.

For the people who want the esp8266 and relay and 230v built in the wall, this looks nice https://ex-store.de/ESP8266-WiFi-Relay-V31#&gid=1&pid=1 Should it be able to flash it with te OTA of that software with espeasy? Nice device, I hope ITEAD will offer soon a proper version of such a thi...

Hi,

now I have a static working solution. I first define a timer, in the rules, then I call it via MQTT:

Code: Select all

/myesp/cmd/TimerSet

Now I can start a predefined timer. The only thing thats missing that I like to "inject" the timer-time first before I start it.

ambassadoro

The sonoff has no sensor for measuring the output wattage. But you can estimate it with calculating the wattage and the switched on time. For example, a light bulb takes 20W while switched on. The swtich-on and off timings you have ready. Maybe this is a shorthand solution. Does not work for a washi...

Do you mean to trigger an event from MQTT? You can send an event using the "event <event>" command on topic <template>/cmd Yes! I like to send to an event. I try this soon. Thank you. And I like to "inject" a value in a rule. for example, a timer-value. For example, a light shou...

Lucky me that I tried first my modified plug and not one burried in the wall

So its just 4 screws away.

I used the bin-file 1M out of the package. Next time, I compile one myself.

ambassadoro

I tried a sonoff-device, now I cannot reach it any more. It said, Update ok and then it dissapeared.

Hi, I created a simple rule to switch on a light when I press a pushbutton connected to a GPIO. on Taster#Taster do if [Taster#Taster]=0 gpio,12,0 else gpio,12,1 endif endon Works great! But when I send via mqtt: mosquitto_pub -q 1 -d -t /Garten/Taster/Taster -m 1 The light is switched on, but when ...

ambassadoro

Great!
That was the solution, I changed from 99 to 17 and now it works!

Hello! I have many mqtt-reconnects in my logfile with the build 113 on a sonoff device. Some month ago, I had kind of the same issue and it dissapeared when I connected a temp-sensor as a device to publish. Unfortunately, in the sonoff is no possibility to define a device sensor. Maybe its a timing ...

Enter in the config page your mqtt-user/password and the domain, there you go!

A good idea is always to check the output voltage of the adapters used.
I have such a usb-breadboard adapter and when its switched to 3.3V, I only got 2.7. It was mostly enough for the esp running alone, but never enough for a sensor.
So, everybody should have the voltage meter ready.

With SSDP you can find your device on the network via uPnP, in Windows it should appear in the network-devices section after a while.

Wikipedia.

Can you do a screenshot of your devices section? This is not easy to understand.

ambassadoro

I got mine yesterday in the evening. Looks good and fast delivery!

But I already face my first challenge: How can I open this little box? Is there a hidden screw? I don't want to break the case.

ambassadoro

My wish: Rock stable MQTT. It works already very well for sensors and simple actors like a relay on a GPIO. Other outputs like PWM, the minipro-extender and other extra IO are not supported or at least not documented. If you need help for documentation, I like to get involved (I tried to login to th...

There is an own souliss-firmware for esp: http://souliss.net/media/how-to-load-a-sketch-on-ESP/
So I think there is no need to bend espeasy to match with soulis.

ambassadoro

With the shell-command this is useful for test purpose. For more automation I am playing around with Home Assistant. It supports mqtt very well and looks much more promising to me than fhem.
Have fun

I was trying to get a pir sensor working with it last night but no joy @ 3v..
!

The usual PIR-sensors from ali can be hacked to work with 3.3V. Maybe thats worth a try.

Hello, there was the question how to drive a GPIO via MQTT: mosquitto_pub -d -t /esp3/GPIO/14 -m 0 The esp3 is the subscription-topic from the advanced section of the esp-configuration webpage: /%sysname%/# Then the GPIO keyword and the number of the gpio that you want to switch. -m 0 is the payload...

I think we do not need unsecure KNX when we have pure MQTT.

I just ordered this one from far east: TTP223B
I am curious what I get. But not even 0,5€ is worth a try. What I am wondering is that it has a kind of timeout with 12 seconds. But lets see. Around easter-time it could arrive.

ambassadoro

Or is there any other way to either make the homemade capacitve sensors or a touchsensor module ( like http://kultogbillig.no/Kapasitiv-Touch-Sensor-Bryter-Modul-For-Arduino-Capacitive-Touch-Switch-Module) work with ESPeasy and openhab/domoticz? I read the description and I think this module could ...

Hi,

I have orderered these power-suppliers:PowerSupply and then I want to go down to 3.3V with those: DCDC.

The power-supply was tested once from a danish expert: Expert.

But, all in all this comes up to 3€ per power supply. Thats far away from the 1€ supply that tozett mentioned.

Hello!

Is this solved in later versions?

I am running R48 on my sensor-box, too. After a while, it stops sending mqtt messages. I can reach the webfront and reboot the system, then it starts again sending sensor-data. Unfortunately, my small ESP can't get OTA and its under the roof.

Hello, I have updated from R72 to R73 over the air and that worked very nice! Now I get every 15 seconds (guess): MQTT : Connection lost MQTT : Connected to broker And after a while a countdown from 60 to 0 and a reset. I am using an ESP12E with no devices connected. Update: I have defined a device ...

ambassadoro

Good idea.

Another tipp is to use an RC-grid for the connection of CH_PD. A 4.7k resistor and 0,1uF. I have done that and its much more stable now and can better start.
Thats my mileage for this week with such a setup.

Uptime: 5600 minutes

(with Build 48).

ambassadoro

Interesting item. I ordered some. Lets see.
As its possible to install espeasy, do you think its possible to connect more sensors like DS18B20 or light sensor to that little fellow?

ambassadoro

Hi,
I am using the rainy sunday to try around with a pulse counter. I get the pulses counted and can see the actual counts and the total sum on the website of esp.
But in mqtt it submits only the actual count, not the total sum.

I only get one line

Code: Select all

/esptest/Tick/Count 0.00

Hi, I connected a HC-SR04 via a level shifter (like this ). I have connected it via gpio4,5. Other devices I have is a DS18B20 and a light sensor, they both deliver good values. But the distance sensor show me values like 0.17 (when its meters, its ok from my desk to the ceiling) and often values li...

Double check the cabling and the power source. This often helps alot.

For doing freezing-tests, I use pressurized air in spray cans, use the can upside down and it emitts liquid gas. Be careful! Its flammable.

ambassadoro

Hi! How have you connected the power? I have the same problem from time to time. It could be the CH_PD. That should be pulled to VCC during boot, but only after the VCC is really ready. Maybe it can be solved with a small capacity to ground and a resistor on CH_PD. Its worth a try. We (all the commu...

ambassadoro

Thanks! That was the solution! First, I resoldered the pins, then I had always 15 of intensity. Then I checked it with a microscope and found, that the sensor looked very dirty, maybe not cleaned well after soldering in the production. I wiped it softly and now it seems to work. At least I get diffe...

Hello,

I have connect a lux-sensor BH1750. The only value thats shown is 54627.50. It doesn't matter if its in a dark box or in bright light. What have I done wrong?

ambassadoro

Could be done with a piezo like this and pwm:
Ebaybuzzer.

ambassadoro

Try to stabilize the power. That often helps alot. A bigger capacitor between + and ground can help to bring enough power when needed.
