## [1.9.5] 30-04-2020

### Added
- Solar Module SM200 support
- Support writing to Junkers FR100 thermostats

- `mqtt_nestedjson` option to disable multiple data records being nested into a single JSON string
- MQTT publish messages are queued and gracefully published every second to avoid TCP blocks
- Added features to WW messages (0x33, 0x34) to improve WW monitoring. (PR#338 by @ypaindaveine)
- Added mixing log and stub for EMS type 0xAC (PR#338 by @ypaindaveine)
- Added Thermostat retrieving settings (0xA5) (validated on RC30N) with MQTT support (thanks Yves @ypaindaveine. See #352)
- Merged with PR https://github.com/proddy/EMS-ESP/pull/366 from @MichaelDvP fixing RC20 and MM50

### Fixed
- set boiler warm water temp on Junkers/Bosch HT3
- fixed detection of the Moduline 400 thermostat
- RC35 setting temperature also forces the current select temp to change, irrespective of the mode

### Changed
- improved MQTT publishing to stop network flooding. `publish_time` of -1 is no publish, 0 is automatic otherwise its a time interval
- External sensors (like Dallas DS18*) are sent as a nested MQTT topic including their unique identifier
- `mqttlog` console command renamed to `mqttqueue` to only show the current publish queue
- `status` payload on start-up shows the IP and Version of EMS-ESP
- `thermostat mode` takes a string like manual,auto,heat,day,night,eco,comfort,holiday,nofrost
- `thermostat temp` also takes a mode string, e.g. `thermostat temp 20 heat`
- `queue` renamed to `txqueue`

### Removed
 - `autodetect scan`. Replaced with `devices scan` and `devices scan+` for deep scanning
 - `mqttlog all` and showing MQTT log in the web interface - no point showing history of previous mqtt publishes in ESP's precious memory. For debugging I recommend using MQTT Explorer or another external tool.

## [1.9.4] 15-12-2019

There are breaking changes in this release. See `publish_time` below and make sure you set this value to 0.

### Added

- Added `publish_always` forcing MQTT topics to be always sent regardless if the data hasn't changed
- Support for DHW once (OneTime water) heating command via MQTT [issue 195](https://github.com/proddy/EMS-ESP/issues/195)
- Added scripts to automatically build firmware images on every Commit/Pull and nightly builds using TravisCI
- Added option to WebUI to also download the latest development build
- Added build scripts for automated CI with TravisCI

- `log w <type_id>` for watching a specific telegram type ID
- initial support for EMS+ GB125s and MC110's
- Buderus RFM200 receiver

### Fixed

- Stability for some Wemos clones by decreasing wifi Tx strength and adding small delay

### Changed

- Debug log times show real internet time (if NTP enabled)
- `system` shows local time instead of UTC
- fixed version numbers of libraries in `platformio.ini`
- Normalized Heating modes to `off`, `manual`, `auto`, `night` and `day` to keep generic and not Home Assistant specific (like `heat`)
- Keeping Thermostat day/night modes separate from off/auto/manual, and setting this for the Junkers FR50
- Removed `publish_always`
- Changed NTP interval from 1 hour to 12 hours
- Refactored EMS device library to make it support multi-EMS devices easier (e.g. multiple thermostats)
- `autodetect deep` removed and replaced with `autodetect scan` for scanning known devices.
- MQTT data will be sent when new data arrives. So `publish_time` is used to force a publish at a given frequency (2 mins is default), or 0 for off.

### Removed

- thermostat scan and autodetect deep functions
- removed Event Logging to SPIFFS (worried about wearing). Replaced with SysLog.

## [1.9.3] 2019-10-26

### Added

- Report # TCP dropouts in the `system` command. These could be due to WiFI or MQTT disconnected.
- Added temp and mode to the MQTT `thermostat_cmd` topic
  
### Fixed

### Changed

- Heartbeat MQTT payload is now in JSON
- platformio.ini targets. Use `debug` for custom builds.

## [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.
 - 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 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

### Removed

- Hid access from telnet to the Experimental custom function command 'x'
- Tx and Rx stats have gone from the stats page, as they were pretty meaningless
- Removed NO_TX define in platformio and replaced with system parameter 'command X'
- Removed -DDEBUG option in build
- Removed wwtemp MQTT messages to set the boiler temp. You'll never miss it.
- Removed LEDs for Tx, Rx and Err. Too many flashing lights and it drains the current.
- Removed capturing of last Rx and Tx times
- Support for older RC20 thermostats

### Known Issues

- There's a nasty memory leek when in telnet's verbose mode with sending which causes the EMS to reset when running for a while.
