Development Build v.2.3.3b2

Understand the iRT-bus

• Added Code for Get-Commands to debug the contents of the iRT-bus
• changed minute-timer to period-timer
• changed calculation of the burner power to get full 100%
• added 0x73 & 0x78 raw telegram on setting heating activated on/off (sometimes boiler does not start, even flow temperature and burner power is set)
• bugfix burner starts
• changed "Max temperature" to "Actual boiler temperature" (but assume this is safety temperature probe)

version 2.3.2

Fixed active mode

• added additional memory alignment directives
• bug-fix command: set_max_power
• bug-fix reading burner starts
• bug-fix reading current burner power on startup
• separated EMS- and iRT-code in emsesp.ccp / incoming_telegram and telegram.cpp / send
• combined single telegrams (up to 5) for send out (increased rx/tx buffer)
• bugfix for telegrams w/ 0x00 as last byte
• fixed issue w/ only every 2nd telegram survive

Development Build v.2.3.2b3

Version with write capabilities (Active Mode)

• Adding active mode (known bug: only every second telegram survives :-( )
• Additional debug-outputs
• not yet included: PID-control
• Adding fast fetching mode (10 sec) for selected telegrams
• changed topic for MQTT commands to device + "_cmd"
• added more values to RTC-memory due to frequent restarts

Known bug: frequent restarts if heatingActivated = false

version v2.3.1

• finally solved frequent restarts if rx-fails occur --> RC were unhandled read-requests due to passive mode.
• added 5 minute down-timer. Seems to be triggered if burner starts for heating (not for warm-water)
• added additional memory alignment directives (still not know, if really necessary)
• combined telegram (0x73, 0x78, 0x01/0x07) will be dropped, if crc-error in one of them. No problem for now, because 0x73/0x78 are unknown)

Development Build v.2.3.1b4

• Add many compiler attributes to avoid missaligned memory. Not sure, if all are necessary. But still restarts happen
• putting gas reading into RTC memory (because of restarts). But if too many restarts, value is not accurate
• correct boiler variable assignments
• correct boiler "changed" checking
• moved UART ISR into IRAM
• enabled settings write if Gas Reading will be changed
• correct text for IRT telegram-ID 0x07
• enabled VCC-measurement for analog input
• increased max telegram length to be sure that enough space if read errors occur

Development Build v.2.3.1b3

• Fixed Watchdog resets on registering HA discovery topics. Need to put all messages into publish queue. For that several loops needed for the boiler,

• increased MQTT queue to 25

• added gas meter reading in boiler list

• back to custom MMU settings

• Added boiler specific settings to customaize iRT boiler

• correct typecast for external temp.

• changed default settings for WiFi to irt-esp

• added settings to calculate the gas-meter-reading based on the power of the bruner

• dallas sensors and shower device now also have config based on the mqtt-base

• added iRT "product-ID" 255 which will read boiler specific settings from flash

• changed boiler wWHeat to ww3wayValve

• added iRT commands to boiler test

version v2.3.0

Updated v2.2.3b0 to receive iRT-telegrams
This commit/fork based on the work of proddy's EMS-esp-project (2.2.3.b0) and the work of Victor-Mo's iRT-esp-project.

• Added the abbility to read iRT-telegrams (plan for writing exists)
• Support for multiple EMS/iRT-ESPs with MQTT and HA
• MQTT discovery for status values
• Added additional status values
• Free up stack using DynamicJsonDocument also for smaller Json Docs.
• Added buildflags to try to improve memory handling (I'm new on this, may it's contraproductive)
• Added many debug-output to understand what's going on ;-)
• Changed default TX-mode to iRT-passive
• start with new version number 2.3.0

Known issues:

• restart due to exception 29 after several hours
• till today also MQTT values for non-iRT-sensors after a while. Not sure, if this is fixed now.

NOT YET tested with EMS-devices, but I tried to keep all functionality for EMS & iRT
