Sensebender Micro + button
-
Hi!
Regarding the scrolling not working while in edit, yeah, I experiencing that also. I'm on Chrome 47, Ubuntu. I always have to edit in full screen.
This is my sketch for a sensebender connected to my door bell:
2016-02-29: Updated sketch to fix bug in siVolt calculation and set max vcc to 3.2 V.
/** * 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. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0 - Thomas Bowman Mørch * * DESCRIPTION * Default sensor sketch for Sensebender Micro module * Act as a temperature / humidity sensor by default. * * If A0 is held low while powering on, it will enter testmode, which verifies all on-board peripherals * * Battery voltage is as battery percentage (Internal message), and optionally as a sensor value (See defines below) * * * Version 1.3 - Thomas Bowman Mørch * Improved transmission logic, eliminating spurious transmissions (when temperatuere / humidity fluctuates 1 up and down between measurements) * * Added OTA boot mode, need to hold A1 low while applying power. (uses slightly more power as it's waiting for bootloader messages) * * MODIFIED by Martin Hjelmare * Sensebender Micro default sketch with addition of binary switch and interrupt, * taken from Patrick 'Anticimex' Fallberg's sketch BinarySwitchSleepSensor. * Also fixed the bug with the diff calculation for the temperature, and changed * vcc 100% rating to 3V, instead of 3.3V. */ #include <MySensor.h> #include <Wire.h> #include <SI7021.h> #include <SPI.h> #include "utility/SPIFlash.h" #include <EEPROM.h> #include <sha204_lib_return_codes.h> #include <sha204_library.h> #include <RunningAverage.h> //#include <avr/power.h> // Define a static node address, remove if you want auto address assignment #define NODE_ADDRESS 1 // Uncomment the line below, to transmit battery voltage as a normal sensor value #define BATT_SENSOR 199 #define RELEASE "1.3" #define AVERAGES 2 // Child sensor ID's #define CHILD_ID_TEMP 1 #define CHILD_ID_HUM 2 // How many milli seconds between each measurement #define MEASURE_INTERVAL 60000 // How many milli seconds should we wait for OTA? #define OTA_WAIT_PERIOD 300 // FORCE_TRANSMIT_INTERVAL, this number of times of wakeup, the sensor is forced to report all values to the controller #define FORCE_TRANSMIT_INTERVAL 30 // When MEASURE_INTERVAL is 60000 and FORCE_TRANSMIT_INTERVAL is 30, we force a transmission every 30 minutes. // Between the forced transmissions a tranmission will only occur if the measured value differs from the previous measurement // HUMI_TRANSMIT_THRESHOLD tells how much the humidity should have changed since last time it was transmitted.

@tbowmo "call of overloaded 'set(float&)' is ambiguous"
I don't know what it mean.
And i don't know why the very first sketch is working for you and not for me ! :sweat_smile:/******************************************** * * Sends battery information (battery percentage) * * Parameters * - force : Forces transmission of a value * *******************************************/ void sendBattLevel(bool force) { if (force) lastBattery = -1; long vcc = readVcc(); if (vcc != lastBattery) { lastBattery = vcc; float siVolt = vcc / 1000; #ifdef BATT_SENSOR gw.send(msgBatt.set(siVolt)); #endif // Calculate percentage vcc = min(vcc, 3000L); // vcc max is 3000 vcc = vcc - 1900; // subtract 1.9V from vcc, as this is the lowest voltage we will operate at long percent = vcc / 11.0; gw.sendBatteryLevel(percent); transmission_occured = true; } } /*******************************************f```No quote, no forum notification (else, the mail box ring every minutes !).

BATT_SENSOR si declared.
... I think msgBatt is not.
Does it should be here ?// Sensor messages MyMessage msgHum(CHILD_ID_HUM, V_HUM); MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);Wait not it's just under:
#ifdef BATT_SENSOR MyMessage msgBatt(BATT_SENSOR, V_VOLTAGE); #endifNo quote, no forum notification (else, the mail box ring every minutes !). Thanks, and have a very good MySensors day !

Try declaring siVolt outside the if block in the battery function.
Edit: Scrap the last suggestion.

If I undefine: //#define BATT_SENSOR 199
it's working.
But your code still not 100% so we have to find why.
But... but, i think i'm making a mistake: yes i plan to use 3volts power. But, i don't want it as a sensor ! I wan't it as a battery level like the very first SensebenderMicro sketch. So... I have to undefine BATT_SENSOR ? And i will not have it set to 3Vcc=100% ?

Might you need to specify decimals if sending float as message. If you want to try, add a second argument with an integer number for decimals.
https://github.com/mysensors/Arduino/blob/1.5.3/libraries/MySensors/MyMessage.cpp#L212 -
void sendBattLevel(bool force) { if (force) lastBattery = -1; long vcc = readVcc(); if (vcc != lastBattery) { lastBattery = vcc; float siVolt = vcc / 1000; #ifdef BATT_SENSOR gw.send(msgBatt.set(siVolt, 2)); #endif // Calculate percentage vcc = min(vcc, 3000L); // vcc max is 3000 vcc = vcc - 1900; // subtract 1.9V from vcc, as this is the lowest voltage we will operate at long percent = vcc / 11.0; gw.sendBatteryLevel(percent); transmission_occured = true; } } -
The measurement method is not accurate at all. It relies on an internal reference that can vary in value between boards (I can't remember the accuracy of it at the moment)
If you don't want the battery voltage, then uncomment the #define for BATT_SENSOR in the top of the sketch, and move the float siVolt = vcc/1000; to be within the #ifdef BATT_SENSOR like:
#ifdef BATT_SENSOR float siVolt = vcc / 1000; gw.send(msgBatt.set(siVolt, 2)); #endifNow it should compile, and send battery percentage as the standard sensebender sketch.

I personaly think that it's quite good. When powered by FTDI, it found 3.00V.
And I have only add the "//" to BATT_SENSOR and it work good.
(you inverted the thing in the message just above).Thanks again for you help.
Now i work very good and very fast. I just have to check for adding an antenna to the controller. -
@Pierre-P How do you find the battery life please? I am planning to fit Sensebender with nrf24l01+ SMD and CR2032, but I wonder how long the battery is going to survive? Appreciate if depends on your sketch, but given one is conservative (i.e. no need to send temp/hum every 30-60 sec, but probably every 5-10mins or so), what's your estimate please?
-
I can't tell you for the moment, I haven't check the real voltage of the CR2032 at the beginning. I'll try to make two mesure between 30 days.
But my sketch is 1800000ms or 30min sleeping (if no-one press the button). Because it's a redundant information, my Jeedom controler have a meteo plugin who's working good. (i'll use it for the mini-night-temperature to have a message if there is glass on my car's windows). -
