v4.5.0

Full Changelog: v4.4.0...v4.5.0

• Full-functional NO-IP devices support and bridge between MQTT/HTTP on Master CAN device and CAN-connected slave devices
• Saving config to flash for STM32 (including configs, retrieved via CAN), Checking CRC16 of config on Master can device to avoid unnecessary config retrieving and overwriting
• Modbus fixes & Improvements
• Possibility to exec commands inside GROUP channel definition
• Some critical relability fixes after 4.4.0

v.4.4.0

• Improvements of Modbus Channel: "prefetch" option to check device register before write
• full-functional CAN driver released to allow cross-communication between several LH and to serve NON-IP LightHubs
• LH now working on NON-IP devices - check STM-non-ip target
• Working with several MQTT brokers and auto-fallover
• OTA login & password default options

Full Changelog: v4.3.4...v4.4.0

v4.3.4

Full Changelog: v4.3.3...v4.3.4

Stability fixes:

• Reloading config without restart - ("get" command) - refactored to working in safe section
• Artnet - related issues with reload/restart

Improved code:

• Modbus v2 driver working correctly in case of concurrent registers write (write while controller awaiting response from Modbus device)
• AC Haier - improved functionality - ON/OFF XON/XOFF turning ON AC without mode switch
• Multizonal ventilation and PID fine-tuned to working smooth with Zentec wall-panels seamless with HomeAssistant
• Modbus exchange moved to Additional log level 9
• Logs clean-up

Tested on

• lighthub HW
• due
• esp32
• esp8266
• Mega 2560

v4.3.3

Full Changelog: 4.3.2...v4.3.3

• DMX Input fixes/refactoring & synchronization with channels state
• Mercury counter restored after core refactoring
• Logs cleating & unification
• Timer TC0 priority decreased (0->2) to avoid impact to Serial (DMX IN/OUT, Modbus) and I2C (1-wire and other sensors) exchange. Critical.
• Some core improvements, refactoring and optimisation

4.3.2

Full Changelog: v4.3.1...4.3.2
fix timed command for none-group channel
Improved 1-wire/I2C devices auto-reset
template functionality for "Emit:" topic name. Example: {"emit":"${root}/${out}/ch1${sfx}"}
(Need to use up-to-date dep. libs for compilation)

v4.3.1

Full Changelog: v4.3.0...v4.3.1

• 1-wire fixes if uses together with other sensors (DHT, I2C)
• I2C devices auto-reset/restoring if devices glitches
• some core & multitasking refactoring
• input checking on interrupt fixed

v4.3.0

Full Changelog: v4.2.0...v4.3.0

New functionality

• New format for timed commands (for example "ON 1000" - ON for 1s, then OFF)
• FREEZE and UNFREEZE command to lock/unlock changes on chanel
• ENABLE/DISABLE commands allow/disallow XON command for channel and on-off PID regulator
• FLASH saved config cleaning by long press button on start (CONFIG_CLEAN_PIN=XX compilation option)
• Modbus v.2 driver supports all types of registers: holding registers, input registers, coils, discreet inputs
• Additional mapping logic register->command/value ('def' mapping parameter allow additional mapping if primary mapping not succeed)
• Digital signature (SHA256) checking for commands against "Protected PINS" allow to increase security level to operate with "sensible" circuits (e.c garage doors opening etc)
• Mottura X- Nova lock's dry contacts integration

Improvements/bugfixes

• 1-wire legacy code refactored (no auto-scanning of 1-wire device, use CLI command 'scan' )
• Modbus legacy code fixed (re-trying commands fixed)
• mac address NVRAM saving fixed
• config reloading process refactored

Documentation updated (RU) on https://www.lazyhome.ru/dokuwiki/doku.php?id=start

v4.2 - New functionality & improvements

New functionality
Control up to 4 Air conditioners
-D NOSERIAL option to release Serial from debug output and use for any purposes
Mercury electricity counter channel type (and ability to share bus with Modbus devices)
New channels commands:

• ENABLE
• DISABLE
• FREEZE
• UNFREEZE

Ability to use timed commands: for example: ON 60000 mean ON now and OFF after 60 sec
DHCP fallback (using last known IP address if DHCP failed)

Fixes and improvements:
Up to 20% RAM saving on huge JSON configs (avoid same text strings in RAM)
Counter - now based on integers (not float) to avoid precsision loses
DHT22
ESP8266 firmware - slimming to allow OTA on ESP12
MBUS universal driver completed
PID
MultiZone ventilation

Bugfix release

• Modbus negative values fix
• Parsing of values between 0 and 1 fixed
• Modbus optimized and relability increased
• PID: fixes, added minimum and maximum output limits
• issue with config saving to flash, if config size>20K (DUE) fixed/refactored

v4.1.0

(!) Complete Modbus v2 two-way mapping functionality (both, command and values)
PID enable/disable command
PWM Relay fixes
