v5.3.0

what's new

direct GitHub Update 🎉🎉🎉

This update introduces an exciting new feature: You can now update to the latest version directly from GitHub in the WebUI – no need to download the .bin file manually anymore!

Simply click on the version info in the bottom left corner, or the new Button in the Tool Section and a dialog will open. If a new version is available, you can initiate the update right there. It will automatically download and install the latest release from GitHub.

Tip

Maybe it is necessary to clean your browser cache after the update, to be sure that everything works well!

encrypted Passwords

Passwords are now better protected and stored in encrypted form in the config.json
When updating, the existing passwords are automatically encrypted and saved again.

effected config elements:

• WiFi Password
• Web Authentication Password
• MQTT Password
• Pushover API_Key
• Pushover User_Key

Caution

As the passwords are stored in encrypted form after this update, it is no longer possible to switch to an older version without re-entering the passwords after the downgrade

v5.1.0

what's new

This is a minor update version, but it is based on a major update 5.0.0
Please see here what´s changed in release v5.0.0

Important

unfortunately there was a bug in the MQTT handling in v5.0.0 which led to commands not being accepted correctly. Therefore please update to this version if you are already using 5.0.0!

reminder Ethernet Extention

I would also like to point out again that since V5 it is possible to connect the ESP via Ethernet.
Daniel already has a great expansion board designed for this, which you are welcome to register for.

new functions

• now the active Page is highlighted in the navigation bar.
• due to the increased number of possible used GPIO´s - there is a check whether the GPIOs are valid and individual GPIOs are not configured multiple times

changelog

• bugfix incorrect handling of received mqtt payload #131
• bugfix incorrect heap usage value
• change mqtt client-id back to WiFi-Hostname #128
• no restart of the ESP if the WiFi connection cannot be established but there is an Ethernet connection.
• interval for renewed mqtt connection attempt increases with each attempt by a further 10s (max. 50s). The ESP restarts after 5 failed attempts
• change previous used Libraries for DS18B20 sensors to mathieucarbou/MycilaDS18
• add function to check whether the configured GPIOs are valid and have not been assigned twice
• highlight active page in sidebar navigation
• update Readme.md

v5.0.0

what's new

This is a major update with some new features and some redesign under the hood.
The Framework is updated to the new Arduino v3 based on ESP-IDF v5.1+
Several modifications have been made to achieve better performance and stability.

Performance and stability improvements

Various improvements have been made to increase performance and stability. In particular, the communication between ESP and the web server has been redesigned and improved. The protocol was changed from SSE (Server-Sent-Events) to Websockets.
The maximum number of client connections is monitored and limited to the number of 2 active connections.

Ethernet Support W5500

There is a new support for W5500 Ethernet Modules. This brings the possibility to use ethernet connection in parallel to WiFi connection.
This could be useful in situations where the WiFi connection is not available or stable.

For mor details, please have a look at the documentation

There is also an expansion module in the pipeline that fits perfectly on the KM271 WiFi board.

Solar Support FM244

Support for optional Buderus Solar Module FM244 added. You can activate this in the same way as the heating circuits and hot-water.
Values are send by mqtt and are also available in the webUI.

System Logger

The logging function has been extended. The mode can now also be switched to ‘System log’. In this case, the serial monitor is redirected to the log and you can see the messages that are normally only visible when you are connected via cable.

new HC1/HC2 Control Elements

There are new HC1/HC2 control elements on the web UI

• HC1 Day Temperature / HC2 Day Temperature
• HC1 Night Temperature / HC2 Night Temperature
• HC1 Holiday Temperature / HC2 Holiday Temperature
• HC1 Switch-On Temperature / HC2 Switch-On Temperature

additional Status Information in the web UI

There are some additional information in the status Tab of the web UI

• Status information about Ethernet connection
• Status information about KM271 connection
• Status information about MQTT connection

BREAKING CHANGES!!!

Important

In the past, there was a separate setting for the static IP. Now we have two possible interfaces and therefore the static IP setting is also duplicated and is located together with the WiFi and Ethernet settings. If you previously used static IP, you will need to adjust your settings.

I would recommend deactivating the static IP before the update!

v4.1.4

what's new

only stability improvements

changelog

• bugfix possible problems when connecting webUI clients. #116

v4.1.3

what's new

There are some changes to MQTT Discovery for Home Assistant

Important

with v4.1.2 the discovery config for "HK1_Sommer_ab", "hc1_summer_mode_threshold and "WW_Zirkulation", "ww_circulation" has changed.
Therefore, it may be necessary to delete the old Discovery Config manually.
This can be achieved by manually sending an MQTT message with the appropriate topic and an empty payload.
Alternatively, with this version you can also reset all config messages via Telnet (ha resetconfig) and also resend the config via command (ha sendconfig)

Example for german Topics (payload empty):
old Topic: homeassistant/number/Logamatic/HK1_Sommer_ab/config
old Topic: homeassistant/sensor/Logamatic/WW_Zirkulation/config

changelog

• bugfix Home Assistant setvalues not working - this bug was introduced in v4.1.2 #108
• add function to send MQTT discovery manually via Telnet (> ha sendconfig)
• add function to reset MQTT discovery manually via Telnet (> ha resetconfig)

v4.1.2

what's new

There are some changes to MQTT Discovery for Home Assistant

changelog

• fixes the behavior that the devices are "not available" in Home Assistant, after Home Assistant has restarted. #108
• change control for "summer threshold" from Slider to DropDown
• add support to control "warm water pump circulation" at Home Assistant #110
• add restart button in Home Assistant

v4.1.1

what's new

some smaller changes and fixes

changelog

• fix login problem #109
• add info dialog for GPIO settings
• add exhaust temp for HA discovery

v4.1.0

what's new

with this version comes the first implementation of mqtt discovery for Home Assistant 🎉

Unfortunately I have to do some breaking changes!

Home Assistant mqtt auto Discovery

MQTT discovery for Home Assistant makes it easy to get all values in Home Assistant.
The Logamatic values will automatically visible as mqtt device in Home Assistant.
The config values and the status values are displayed. Some config values can also be changed as in the WebUI.

As this is the first implementation, let´s see this an experimental state.
I am open for feedback and further improvements. Please use the issues and discussion section.

BREAING CHANGES!!!

Important

In the past, there were separate mqtt topics defined for the setvalues of the logamatic config values.
These topics were similar to the config Topics itself, but unfortunately there were some differences.
Now the setvalue topics are the same as the config topics.

some examples:

OLD: {"/setvalue/hk1_tag_soll", "/setvalue/hc1_day_setpoint"} => NEW {"/setvalue/HK1_Tagtemperatur", "/setvalue/hc1_day_temp"}
OLD: {"/setvalue/hk1_frost_ab", "/setvalue/hc1_frost_mode_threshold"} => NEW {"/setvalue/HK1_Frost_ab", "/setvalue/hc1_frost_protection_threshold"}
OLD: {"/setvalue/hk1_ferien_tage", "/setvalue/hc1_holidays"} => NEW {"/setvalue/HK1_Ferien_Tage", "/setvalue/hc1_holiday_days"}

To be more compatible, it is possible to use upper and lower case letters in the german setvalue topics.
It is also now possible to use the "string options" instead of num values as this is necessary for the home assistant integration.

examples:

• hc_operation_mode - payload: "day", "night", "auto"
• hc1_reduction_mode - payload: "off", "fixed", "room", "outdoors"
• hc_program - payload: "custom", "family", "early", "late", "AM", "PM", "noon", "single", "senior"

changelog

• fix value of HCx_SwitchOffOptimizationTime, HW_SwitchOffOptimizationTime (was not set before)
• If there is a whitespace in optional sensor name, it will be replaced in the responding mqtt topic
• Fixes the saving of the hostname. This was previously saved incorrectly as wifi.ssid which made the WiFi settings unusable. #98
