ESPEasy - multisensor device based on esp8266

---

The ESP Easy firmware can be used to turn the ESP module into an easy multifunction sensor/actuator device for Home Automation solutions like Pimatic. Configuration of the ESP Easy is entirely web based, so once you’ve got the firmware loaded, you don’t need any other tool besides a common web browser.

Tools Firmware update using OTA or upload binary file over GUI.

Comunication

• http generic protocol - (After a simple adjustment would it be able to communicate with Pimatic via API, If you would be interested, let me know.)
• http commands (Actuator can be controlled via http commands, not even in ESPEasy configure anything!) e.g. http://<ESPIPaddress>/control?cmd=PWM,<pin>,<level>
• mqtt protocol (In pimatic fully supported via MQTT plugin). Including the response to the external condition.
• json data (Simple json object) over http://<ESPIPaddress>/json
• Serial Commands over web interface

Very interesting feature is the Local level control that lets you control GPIO according to the values of sensors/GPIO state directly in firmware. Thus, without an external control system or in combination.

Try deleting /home/harryvanderwolf/Arduino/libraries/Servo

Yes, that did it indeed. I’m now using the default servo library from arduino.

I added mDSNS with manual config and that works fine with your ESPEasy.ino

ESPEasy is not my creation! At issue, I recommend: http://www.esp8266.nu/forum/viewforum.php?f=1

It functions but I don’t like to add and configure an extra plugin like MQTT. I think I switch back to ESPimatic

I really like this ESP as sort of a standard solution for sensors.
But I would like to communicate with Pimatic by the api’s (http generic protocol). Wil that be possible to soon?

Thanks in advance…

I had a look at the github repo. It is very modularly setup. All “interfaces” like “generic http”, “domoticz http”, “Domoticz MQTT” and the others are in the _C00x ino’s. It should be possible to copy the _C008.ino (generic http) and modify it to a pimatic version, but my C/C++ days are more than 20 years behind me.

I primarily wanted to control actuators.
When I drove through the API, actuators’d had to deal with a dummy device + rules (http commands). Or write your own modules for actuators.
But even so, I would be quite limited in options. That’s why I focused on MQTT.

Ok, I see that with MQTT is should work well with Pimatic.
But is there a tutorial (or examples) how to connect this to Pimatic? Which MQTT protocol for example, and how to make a device in Pimatic?

Thanks in advance.

@lschip
Sorry, I’m going to write the new guidance, but there is so little time.
Only in speed: Use OpenHub MQTT protocol, this is a purely MQTT. Only for historical reasons so named. It will soon be replaced by Generic MQTT.
And one example actuator (pwm) on 15 GPIO (In ESPEasy not need to configure anything about Actuator):

    {
      "name": "MQTT Dimmer",
      "id": "mqtt-dimmer",
      "class": "MqttDimmer",
      "topic": "wemosd1r2/pwm/15",
      "resolution": 256
    }

Analogously http command: http://<IP>/control?cmd=pwm,15,255

I’m a little sad about the point 36. Well, perhaps it takes someone else. Or I, but only in extreme cases
