1.9.2

[1.9.2] 2019-10-19

Important! This build has breaking changes:

• MQTT topics have changed. Use the mqttlog command to see the names of the subscriptions and the format of the payload data. Also reference the Wiki page.
• Home Assistant .yaml files need updating to reflect the recent MQTT changes
• The web builder has been upgraded to use Gulp 4. Remove tools/webfilesbuilder/node_modules and re-install the libraries using npm ci from within the tools/webfilesbuilder folder

Added

• Handling of Mixing Module MM100 Status Messages (thanks @kstaniek)
• Retrieve/Set thermostat mode for Junkers FW100/120 thermostats (thanks @Neonox31)
• Added sending of all Mixer Module data via MQTT (thanks @peclik)
• Improved handling of MQTT publish and subscribe errors
• Added MQTT QOS (mqtt_qos, default 0), Keep Alive (mqtt_keepalive, default 60 seconds) and Retain (mqtt_retain, default off) as parameters to both telnet and WebUI

Fixed

• publish command also sends Dallas external temperature sensor values
• log_events setting wasn't persisted in config file

Changed

• External dallas sensor values sent in MQTT payload as float values and not strings
• All MQTT topics for the Thermostat have the Heating Circuit appended (e.g. thermostat_data1). This includes the commands.
• Shower timer and shower alert and not MQTT published at boot up
• Heating Active logic change to use Selected Flow Temp of min 30 instead of 70 (#193)

Removed

• Removed telnet command shower timer and shower alert to toggle the switches

1.9.1

[1.9.1] 2019-10-05

Added

• Support for multiple Heating Circuits - #162
• new mqttlog command also shows which MQTT topics it is subscribed too
• Optimized event log loading in web and added integrity checks on all config and log files during boot
• autodetect quick
• log_events option, now optional to save the log events to SPIFFS

Fixed

• fixed zero values (0.0) for setpoint temperature with the RC35 thermostat when in Auto mode - #180
• added check for corrupted event log, which could happen due to SPIFFS writing while UART is active
• made Junkers work again (broke in 1.9.0)

Changed

• Web login password is now mandatory
• Faster detection of EMS devices on bus by using the 0x07 telegram instead of the brute-force scan
• Fixes to the default HA climate component .yaml file to support latest Home Assistance ('heat' added)
• Update documentation in Wiki on MQTT and troubleshooting
• Slowed down firmware upload via the Web to prevent users rebooting too early
• Change way WiFi is intialized to prevent dual AP and Client

Removed

• Removed heating_circuit config setting
• Removed showing the JSON config files when Saving from the Web

1.9.0

Breaking Changes

Important! From this release a new format has been introduced for saving the system configuration and when migrating from previous versions (1.8.x and earlier) your settings will be lost. When 1.9 is installed over a 1.8.x version EMS-ESP will revert back to Access Point mode. You will need to join this wifi AP and use the web interface (https://192.168.4.1) to re-enter your settings.

Changed

• New web interface with more features showing Boiler, Thermostat, Solar Module and Heat Pump. See https://github.com/proddy/EMS-ESP/wiki/Running-and-Monitoring on how to build yourself

• Merged with @susisstrolch's TxMode2 branch for improved support for sending EMS packages. This is the default tx mode.

• Upgraded MyESP library optimizations for WiFi, AP and error handling

• reboot command renamed to restart to keep consistent with web interface

• Renamed heartbeat to mqtt_heartbeat in config settings

• Renamed MQTT topic "wwactivated" to "boiler_cmd_wwactivated"

Fixed

• Handle Read and Write to EMS+ device logic changed, tested with RC3000

A web interface for easy configuration and real-time monitoring of the EMS bus

1.8.3

[1.8.3] 2019-08-12

Fixed

• Added write support for RC3000

1.8.2

[1.8.2] 2019-08-10

Fixed

• Show correct temperatures for FW120. Issue 166
• LED off works after reboot Issue 167

1.8.1

Added

• Added back -DCRASH in Debug build target for capturing any ESP8266 stack dumps during crashes
• Basic Web Interface, for checking stats and setting wifi credentials. See wiki for more details.
• reset firmware option. If the reset button on the ESP is pressed during boot up sequence (the LED is flashing very fast) all settings are erased and goes into AP mode.
• Added tx_mode back with options 0,1 and 2 until we've fixed option 2 that works for everyone and doesn't reset ESP
• More solar module data captured, thanks to @Vuego123
• Detect thermostat mode for EMS+ RC300/Moduline 3000
• MQTT message to set boiler flowtemp (boiler_cmd_flowtemp). See wiki.

Fixed

• Detecting unset values in the SPIFFS and setting default values
• Bosch Easy Connect wrongly classified as a thermostat
• Correctly handle telegrams who's size are exactly 32 bytes (e.g. 0x19 MonitorSlow)
• Telnet also available when in AP mode
• Handling of thermostat temperatures that were single bytes and couldn't exceed 25.5 (0xFF) degrees!

Changed

• Improved handling of Solar Modules (thanks @Vuego123)
• publish_wait renamed to publish_time, a value of 0 means disabling all MQTT sending
• How signed shorts are handled such as the current and setpoint temps on RC300s
• Stopped automatic refresh of web page, which causes crashes/memory loss after a short time
• Support HA 0.96 climate component changes
• -DDEFAULT_NO_SERIAL changed to -DFORCE_SERIAL
• some code cleanups, removing NULLS and moving some things fron heap to stack to prevent memory fragmentation
