Weather and Forecast Display for Swedish FHEM users
-
My need for a indoor and outdoor temperature and weather display was a part of my try-out of Fhem as a MySensors Controller. It turned out surprisingly well. A bit of newbie struggling with German, Perl and regExp I admit, but in the end it turned out to be more simple than that. It was actually harder to make it display the weather forecast conditions in Swedish, which was finally solved by using the weather provider condition code, progmem and custum created lcd characters.
I hope bits and pieces can be useful even if you don't want the exact same application.
The project was based on the MySensors display exemple and BulldogLowell's weather station project.
Where some of my modifications to that are:- Removed scene controller button and internal sensor functionality.
- Changed date and time format
- Fewer slides and less static information per slide.
- Some more info from controller (other sensors).
- Weather conditions in Swedish
Controller (FHEM) runs on a RPiB+ and MySensors gateway is Ethernet(W5100). Perhaps it could be necessary to add timers to the controllers "set" transmission code with a faster one. I haven't seen any issues this far (a week).
The wiring is just the basic for radio and display.
And I used this box and this display and i2c-interface.
Slide 1 presents date and time and update-status if time or weather not has been updated in a while (some hours).
Slide 2 Indoor and outdoor temperature and humidity. (preferably from other MYS-nodes, but for this particular project I used the weather service providers data for outdoor temp only because my mys-network hasn't any "outdoor access")
Slide 3 Today's forecast and High temp and Low temp.
Slide 4 Tomorrow's forecast, high temp and low temp.

This is so great! Thank you!
-
Updated display node code to latest version (v2.5). The recent DST change passed without issues.
-
Yahoo world weather service seems to be have closed down. I got the last update the 24th.
-
So I changed the weather service provider to the FHEM-proven Openweather/wetter.com. I still only send the forecast conditions as codes to spare some MyS net traffic. I'm not as confident of my translations this time.
I only post the node code below. For the Fhem part I just followed this Openweather wiki/guide and changed to new ReadingsVal in my myWeather2disp_ntfy macro posted above.
/* EgWeatherDisplay2.6 Weather and Forecast Display for FHEM with Swedish Conditions By m26872, 20160329 changes from 2.5 to 2.6 - Changed weather condition codes and translations due to changed service provider (from yahoo to wetter.com) changes from 2.4 to 2.5 - Automatic DST time for the next 4 years (controller always sync with UTC) - Now use the gw.wait() - Cleaned displays from some static info - Updated child-ids, sensor and variable definitions to to aline with MySensors 1.5 and to avoid unwanted autocreations by fhem. changes from 2.3 to 2.4 - New (correct) translations for some conditions - Removed two unused "scene button" declarations. */ #define STATES 4 #define CLOCK_SYNC_INTERVAL 3600000UL // 1 hour #define DISPLAY_INTERVAL 3500UL // 3,5s #define FIVE_HOURS 18000000UL #define THREE_HOURS 10800000UL #define ONE_MIN 60000UL #define DST_YEARS 5 #define Y2015_DST_ON 1427594400UL // 2015-03-29 02:00 #define Y2015_DST_OFF 1445738400UL // 2015-10-25 02:00 1445742000UL // 2015-10-25 03:00 #define Y2016_DST_ON 1459044000UL // 2016-03-27 02:00 #define Y2016_DST_OFF 1477792800UL // 2016-10-30 02:00 #define Y2017_DST_ON 1490493600UL // 2017-03-26 02:00 #define Y2017_DST_OFF 1509242400UL // 2017-10-29 02:00 #define Y2018_DST_ON 1521943200UL // 2018-03-25 02:00 #define Y2018_DST_OFF 1540692000UL // 2018-10-28 02:00 #define Y2019_DST_ON 1553997600UL // 2019-03-31 02:00 #define Y2019_DST_OFF 1572141600UL // 2019-10-27 02:00 #define INDEX_LIST_LAST_POS 42 //#define DEBUG #ifdef DEBUG #define DEBUG_SERIAL(x) Serial.begin(x) #define DEBUG_PRINT(x) Serial.print(x) #define DEBUG_PRINTLN(x) Serial.println(x) #else #define DEBUG_SERIAL(x) #define DEBUG_PRINT(x) #define DEBUG_PRINTLN(x) #endif #include <avr/pgmspace.h> #include <Wire.h> #include <Time.h> #include <SPI.h> #include <MySensor.h> #include <LiquidCrystal_I2C.h> #define NODE_ID 112 #define CHILD_ID_3 3 #define CHILD_ID_4 4 LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address (Enl: https://arduino-info.wikispaces.com/LCD-Blue-I2C) void (*lcdDisplay[STATES])(); byte state = STATES-1; byte timeCounter = 0; unsigned long lastTime; unsigned long lastClockSet; unsigned long lastClockReceived = 0UL; unsigned long lastWeatherUpdate = 0UL; int indoorTemp = -99; int indoorHumidity = -99; int outdoorTemp = -99; int outdoorHumidity = -99; int todayHigh = -99; int todayLow = -99; int tomorrowHigh = -99; int tomorrowLow = -99; int todayConditionCode = -99; int tomorrowConditionCode = -99; String todayCondition = "Not yet Reported"; String tomorrowCondition = "Not yet Reported"; unsigned long dstTable[DST_YEARS][2] = {{Y2015_DST_ON,Y2015_DST_OFF},{Y2016_DST_ON,Y2016_DST_OFF},{Y2017_DST_ON,Y2017_DST_OFF},{Y2018_DST_ON,Y2018_DST_OFF},{Y2019_DST_ON,Y2019_DST_OFF}}; MySensor gw; MyMessage msgVAR1(CHILD_ID_3, V_VAR1);// outdoor temperature MyMessage msgVAR2(CHILD_ID_3, V_VAR2);// outdoor humidity MyMessage msgVAR3(CHILD_ID_3, V_VAR3);// today's low MyMessage msgVAR4(CHILD_ID_3, V_VAR4);// today's high MyMessage msgVAR5(CHILD_ID_3, V_VAR5);// conditions MyMessage msgBackLight(CHILD_ID_4, V_STATUS); MyMessage msgLVAR1(CHILD_ID_4, V_VAR1); // indoor temperature MyMessage msgLVAR2(CHILD_ID_4, V_VAR2); // indoor humidity MyMessage msgLVAR3(CHILD_ID_4, V_VAR3); // forecast for tomorrow // Swedish weather condition translations stored to flash.

@vorowski Thx for the info. It's been down before so I don't mind trying something else anyway. Maybe I can start presenting and logging forecasts from different prividers and then evaluate them
