 ## [Unreleased]

+## [0.5.1] - 2023-11-05

-### Removed
+- fixes f-string by limes007
+- add description for dns settings by limes007

- 
+## [0.5.0] - 2023-11-04
+
+- fix issue [#21](https://github.com/s-allius/tsun-gen3-proxy/issues/21)
+- register proxy dev as soon as the MQTT connection is established
+- increase test coverage of the Messages class
+- add error counter for unknown control bytes
+- lint code with flake8
+  
+## [0.4.3] - 2023-10-26
+
+- fix typos by Lenz Grimmer
+- catch mqtt errors, so we can forward messages to tsun even if the mqtt broker is not reachable
+- avoid resetting the daily generation counters even if the inverter sends zero values after reconnection
+
+## [0.4.2] - 2023-10-21
+
+- count unknown data types in received messages
+- count definition errors in our internal tables
+- increase test coverage of the Infos class to 100%
+- avoid resetting the daily generation counters even if the inverter sends zero values at sunset
+   
+## [0.4.1] - 2023-10-20
+
+- fix issue [#18](https://github.com/s-allius/tsun-gen3-proxy/issues/18)
+- initialize the proxy statistics
+- avoid resetting total generation counters
+  
+## [0.4.0] - 2023-10-16
+
+- fix issue [#8](https://github.com/s-allius/tsun-gen3-proxy/issues/8)
+- implement [#10](https://github.com/s-allius/tsun-gen3-proxy/issues/10)
+- fix: don't dispatch ignored messages so that they are not forwarded
+- add systemtests
+- fix unit tests, which were broken since version 0.3.0
+- add proxy device to home assistant
+- add statistic counter to proxy device
+- support multiple inverter registration at home assistant
+  
+## [0.3.0] - 2023-10-10
+
+❗Due to the definition of values for diagnostics, the MQTT devices of controller and inverter should be deleted in the Home Assistant before updating to version '0.3.0'. After the update, these are automatically created again. The measurement data is retained.
+
+### Changes
+
+- optimize and reduce logging
+- switch to pathon 3.12
+- classify some values for diagnostics 
+  
+## [0.2.0] - 2023-10-07
+
+This version halves the size of the Docker image and reduces the attack surface for security vulnerabilities, by omitting unneeded code. The feature set is exactly the same as the previous release version 0.1.0.
+
+### Changes
+
+- move from slim-bookworm to an alpine base image
+- install python requirements with pip wheel
+- disable DEBUG log for releases
+- support building of release candidates
+
+## [0.1.0] - 2023-10-06
+
+- refactoring of the connection classes
+- change user id on startup
+- register MQTT topics to home assistant, even if we have multiple inverters
+
+## [0.0.6] - 2023-10-03
+
+- Bump aiomqtt to version 1.2.1
+- Force MQTT registration when the home assistant has set the status to online again
+- fix control byte output in tx trace
+- dealloc async_stream instances in connection termination
+
+## [0.0.5] - 2023-10-01
+
+- Entity icons updated
+- Prints version on start
+- Prepare for MQTT component != sensor
+- Add MQTT origin
+  
+## [0.0.4] - 2023-09-30
+
+- With this patch we ignore the setting 'suggested_area' in config.toml, because it makes no sense with multiple devices. We are looking for a better solution without combining all values into one area again in a later version.
+  
+❗Due to the change from one device to multiple devices in the Home Assistant, the previous MQTT device should be deleted in the Home Assistant after the update to pre-release '0.0.4'. Afterwards, the proxy must be restarted again to ensure that the sub-devices are created completely.

 ### Added

- 
-## [0.0.3] - 2023-09-27
+- Register multiple devices at home-assistant instead of one for all measurements.
+  Now we register: a Controller, the inverter and up to 4 input devices to home-assistant.

 # Overview

-The "TSUN Gen3 Micro-Inverter" proxy enables a reliable connection between TSUN third generation inverters and an MQTT broker. With the proxy, you can easily retrieve real-time values such as power, current and daily energy and integrate the inverter into typical home automations. This works even without an internet connection. The optional connection to the TSUN Cloud can be disabled!
+This proxy enables a reliable connection between TSUN third generation inverters and an MQTT broker. With the proxy, you can easily retrieve real-time values such as power, current and daily energy and integrate the inverter into typical home automations. This works even without an internet connection. The optional connection to the TSUN Cloud can be disabled!

 In detail, the inverter establishes a TCP connection to the TSUN cloud to transmit current measured values every 300 seconds. To be able to forward the measurement data to an MQTT broker, the proxy must be looped into this TCP connection.

 Through this, the inverter then establishes a connection to the proxy and the proxy establishes another connection to the TSUN Cloud. The transmitted data is interpreted by the proxy and then passed on to both the TSUN Cloud and the MQTT broker. The connection to the TSUN Cloud is optional and can be switched off in the configuration (default is on). Then no more data is sent to the Internet, but no more remote updates of firmware and operating parameters (e.g. rated power, grid parameters) are possible.

-By means of `docker` a simple installation and operation is possible. By using `docker-composer`, a complete stack of proxy, `MQTT-brocker` and `home-assistant` can be started easily.

 ```

+## DNS Settings
+
+### Loop the proxy into the connection
+To include the proxy in the connection between the inverter and the TSUN Cloud, you must adapt the DNS record of *logger.talent-monitoring.com* within the network that your inverter uses. You need a mapping from logger.talent-monitoring.com to the IP address of the host running the Docker engine.
+
+This can be done, for example, by adding a local DNS record to the Pi-hole if you are using it.
+
+### DNS Rebind Protection
+If you are using a router as local DNS server, the router may have DNS rebind protection that needs to be adjusted. For security reasons, DNS rebind protection blocks DNS queries that refer to an IP address on the local network.
+
+If you are using a FRITZ!Box, you can do this in the Network Settings tab under Home Network / Network. Add logger.talent-monitoring.com as a hostname exception in DNS rebind protection.
+
+### DNS server of proxy
+The proxy itself must use a different DNS server to connect to the TSUN Cloud. If you use the DNS server with the adapted record, you will end up in an endless loop as soon as the proxy tries to send data to the TSUN Cloud.
+
+As described above, set a DNS sever in the Docker command or Docker compose file.
