Values which gateway reads are others then sensor sends???



  • Hi,
    i have a Problem. Using a sensebender micro as (Test)sensor and a ESP8266 as wifi gateway.
    So my problem is the following:

    This is what the sensor sends out:

    send: 15-15-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=ok:23.5
    send: 15-15-0-0 s=2,c=1,t=1,pt=2,l=2,sg=0,st=ok:64
    send: 15-15-0-0 s=3,c=1,t=0,pt=6,l=1,sg=0,st=ok:00
    send: 15-15-0-0 s=4,c=1,t=0,pt=6,l=1,sg=0,st=ok:00
    

    And this what my gateway gets:

    0;0;3;0;9;read: 15-15-0 s=1,c=1,t=0,pt=7,l=5,sg=0:23.5
    15;1;1;0;0;23.5
    Node-Sensor (yourvariable) 15-1; Value 23.5
    0;0;3;0;9;read: 15-15-0 s=2,c=1,t=1,pt=2,l=2,sg=0:1102839872
    15;2;1;0;1;1090519104
    Node-Sensor (yourvariable) 15-2; Value 1090519104
    0;0;3;0;9;read: 15-15-0 s=3,c=1,t=0,pt=6,l=1,sg=0:00
    15;3;1;0;0;00
    Node-Sensor (yourvariable) 15-3; Value 00
    0;0;3;0;9;read: 15-15-0 s=4,c=1,t=0,pt=6,l=1,sg=0:00
    15;4;1;0;0;00
    Node-Sensor (yourvariable) 15-4; Value 00
    

    The Value for Humidity from S2 looks very strange... Can anybody help me what i do wrong?
    (I tried it with example esp6266 sketch, too -> same strange values)

    Thank you!

  • Could you please post the versions of your ESP8266 library and MySensors library? As mfalkvidd said I had a similar problem and could fix it with newest versions for the ESP8266 gateway (no need to upgrade the nodes if not wanted).



  • Sorry @Anduril i don't know how to figure it out...
    This is the corresponding thread in pimatic-forum:
    https://forum.pimatic.org/topic/1853/mysensors-esp8266gateway-with-direct-rest-api-access-to-pimatic
    but here is the sketch:

    /**
     * The MySensors Arduino library handles the wireless radio link and protocol
     * between your home built sensors/actuators and HA controller of choice.
     * The sensors forms a self healing radio network with optional repeaters. Each
     * repeater and gateway builds a routing tables in EEPROM which keeps track of the
     * network topology allowing messages to be routed to nodes.

     *******************************
     *
     * REVISION HISTORY
     * 1.2 HvdW - add REST-API functionality to push sensor data to pimatic
     * 1.1 HvdW - add mDNS, static ip
     * Version 1.0 - Henrik EKblad
     * Contribution by a-lurker and Anticimex, 
     * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
     * Contribution by Ivo Pullens (ESP8266 support)
     * 
     * DESCRIPTION
     * The EthernetGateway sends data received from sensors to the WiFi link. 
     * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
     *
     * VERA CONFIGURATION:
     * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin. 
     * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
     *
     * LED purposes:
     * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
     * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
     * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
     * - ERR (red) - fast blink on error during transmission error or recieve crc error  
     * 
     * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.
     * The ESP8266 however requires different wiring:
     * nRF24L01+  ESP8266
     * VCC        VCC
     * CE         GPIO4          
     * CSN/CS     GPIO15
     * SCK        GPIO14
     * MISO       GPIO12
     * MOSI       GPIO13
     *            
     * Not all ESP8266 modules have all pins available on their external interface.
     * This code has been tested on an ESP-12 module.
     * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
     * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
     * - Connect GPIO15 via 10K pulldown resistor to GND
     * - Connect CH_PD via 10K resistor to VCC
     * - Connect GPIO2 via 10K resistor to VCC
     * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
     * 
      * Inclusion mode button:
     * - Connect GPIO5 via switch to GND ('inclusion switch')
     * 
     * Hardware SHA204 signing is currently not supported!
     *
     * Make sure to fill in your ssid and WiFi password below for ssid & pass.

  • Yeah the problem is that this is a 1.5 sketch (and this mod of ESP gateway is only working with 1.5 at the moment) and my problem was solved with the newest dev version.
    So I think best would be to make this mod working with current dev.
    For the others reading this: the sketch has changed the incomingMessage procedure to send a REST-API call to the controller (pimatic) to update sensor values. I talked to him and his problem with migrating this to 2.0 is that this incomingMessage procedure is hidden behind the scenes to make the sketch more readable. Can any of the developers say where this function is now, than the author could adopt.


  • Mod

    @Anduril a conversion guide is availabe at https://docs.google.com/document/d/1NKq5uuNdnxF5jWnum7VT32mbKLjuvqlx2A5D1qQ-H3Q/mobilebasic

    If node expects incoming messages, add the following function to handle data:

    void receive(const MyMessage &msg) {}
    

  • Plugin Developer

    This bug should also be solved in version 1.5.4. Have you tried that version? As I remember it, the bug is present only in 1.5.2-1.5.3.



  • @mfalkvidd it's not a node, but a modified version of the gateway. Harry van der Wolf changed it to directly send all incoming data via api to the controller. Therefore he changed the void incomingMessage() to void incomingMessageESP() and called that instead of the old in his gw.begin. Is it possible to manipulate the function for message reading in a similar way with current dev branch?
    Of course it would be best to use the normal ethernet gateway, but for pimatic there is no plugin capable of connecting to an ethernet gateway, only serial is supported. And those interested in having a ethernet gateway don't have the knowledge to programm it.



  • I have same problem using sensebender as node and ESP8266 as wifi gateway with the sense bender node reporting HUM as a 10 digit number. Mysensors 1.5 lib and 2.0.0 ESP8266 (no diff with 2.0.3). Only affects the HUM reading - not the temp or batt voltage. Interestingly a standard mysensors DHT11 node reports HUM correctly in the gateway while simultaneously the sensebender node does not. Will try the Dev library next.
