TasmotaSerial hardware serial detection is swapped started with TasmotaSerial v2.2.0. While keeping the hardware connection unchanged the Rx and Tx configuration parameters need to be reconfigured swapped to align TasmotaSerial single wire to two wire use.

The following configuration will select Hardware Serial and will disable user serial input, SerialLog and force a sensor specific baudrate.

Sensor	GPIO1 (Tx)	GPIO3 (Rx)	Baudrate
MHZ19(B)	60 MHZ Tx	61 MHZ Rx	9600
PZEM004T	62 PZEM0XX Tx	63 PZEM004 Rx	9600
SenseAir	64 SAir Tx	65 SAir Rx	9600
PMS5003	00 None	69 PMS5003	9600
NovaSds	101 SDS0X1 Tx	70 SDS0X1 Rx	9600
SDM120	75 SDM120 Tx	76 SDM120 Rx	9600
SDM630	77 SDM120 Tx	78 SDM120 Rx	9600
PZEM014/016	62 PZEM0XX Tx	98 PZEM016 Rx	9600
PZEM003/017	62 PZEM0XX Tx	99 PZEM017 Rx	9600
MP3 Player	100 MP3 Player	00 None	9600
Tuya Dimmer	107 Tuya Tx	108 Tuya Rx	9600

See Release Information

See Release Information

This release expands the rule functionality with:

• commands like Add, Sub, Mult and Scale allowing floating point arithmetic on sensor data.
• variables like %time%, %uptime%, %sunrise% and %sunset%

Support for the following devices was added:

• Sonoff S26
• Sonoff iFan02
• BlitzWolf or equivalent energy monitoring devices

Removed libraries

• Adafruit_BME680-1.0.5
• Adafruit_Sensor-1.0.2.02 Libraries added
• BME680_driver-bme680_v3.5.9
• C2Programmer-1.0.0
• ESPAsyncUDP-master Updated library
• esp-knx-ip-0.5.1

Starting with TasmotaSerial version 2.0.0 it is possible for serial connected sensors to use the Hardware Serial interface. This solves possible software interrupts failures resulting in lost sensor readings or watchdog/exception reboots. This is especially true for ESP8266/Arduino core version 2.3.0 which, by lack of iRam, does only allow interrupt routines from flash which might lead to before mentioned failures.

When the following sensor configurations are made Hardware Serial is used which will disable user serial input, SerialLog and force a sensor specific baudrate.

Sensor	GPIO1 (Tx)	GPIO3 (Rx)	Baudrate
PZEM004T	59 PZEM Rx	58 PZEM Tx	9600
SDM120	72 SDM120 Rx	71 SDM120 Tx	9600
MHZ19(B)	57 MHZ Rx	56 MHZ Tx	9600
SenseAir	61 SAir Rx	60 SAir Tx	9600
PMS5003	00 None	65 PMS5003	9600
NovaSds	00 None	66 SDS0X1	9600

The current release is compiled with core version v2.3.0. Due to increased wifi issues like no connection and lower signal strength using core 2.4.0 this release falls back to core 2.3.0.

Updated libraries

• TasmotaSerial-2.0.0

To have more flexible control this release introduces rules to act on different events like activated timers, button presses or sensor readings. See the wiki for more information and examples.

To provide more local control 16 timers were introduced for controlling power outlets during different times during the week. Optional webinterface and Sunrise/Sunset support is also available.

The current release is compiled with core version v2.4.0. This is done to use at least a newer version of the core as it allows better interrupt support due to more free iRAM used by the Arilux Rf and Software Serial interrupt handlers. In v2.3.0 my interrupts had to use normal RAM because of lack of free iRAM which sometimes results in software watchdog restarts.

Core v2.4.1 could have been used too but this version has a problem with sleep mode making the device unresponsive and only a serial firmware upload would revive it. See issue #2559 for background information. This version of Tasmota disables sleep mode on core v2.4.1

Updated libraries

• TasmotaSerial-1.2.0

New libraries

• Adafruit_SGP30 1.0.0 + 13 commits
• esp-knx-ip 0.5.0
• esp-mqtt-arduino 1.0.1 + 2 commits and 1 local fix
• Joba_Tsl2561 replacing TSL2561-Arduino-Library
• Multichannel_Gas_Sensor
• TasmotaMqtt 1.1.1

To ease Home Assistant (and Domoticz #1731) configuration a feature called MQTT device discovery is made available for Tasmota switches and lights.

By executing command SetOption19 On this feature is enabled and after a forced reboot a retained MQTT message starting with topic "homeassistant..", as defined in user_config.h HOME_ASSISTANT_DISCOVERY_PREFIX, is send containing parameters used by Home Assistant to configure a switch or a light.

So no user interaction is needed on Home Assistant.

If you manage to let Home Assistant execute a script after it's restart containing a MQTT command like cmnd/your_light/state it will also use the current state of Tasmota without the use of the retain flag so hated by me.

To disable this feature and get rid of the retained message execute command SetOption19 Off and after a forced reboot the homeassistant topic should have been removed from the MQTT server.

Tasmota is build to install on devices with 1MB usable flash. To easily use Over The Air (OTA) firmware updates only half of this flash space can be used by Tasmota as the other half is needed to store the OTA firmware image before it can be installed.

To keep Tasmota this small I had to reduce redundancy as much as possible. I also had to tweak some libraries by removing default features and disable some features in the user_config.h.

This worked kind of fine until version 2.4.0 of the ESP8266/Arduino board manager came along. This version needs an extra 22k for it's libraries and functionality. To provide easy OTA updates I had to tweak Tasmota even further to the point that major features like Emulation almost had to be disabled by default.

Luckily the ESP8266/Arduino board manager software adjusts it's free flash space based on the current program space. This means that a small program has more OTA flash space to use than a large program. I used this feature by providing the tasmota-minimal.bin firmware image containing only MQTT and a webserver which allows for larger Tasmota images by using a two step OTA approach.

• First OTA upload the tasmota-minimal.bin image in the small free space area
• Then OTA upload the final tasmota.bin image in the larger free space area

This process is now automated if used with an external OTA server.

Tasmota now tries to load the requested image and if it notices that the image won't fit it will load the minimal version first which in turn will load the requested final image. This is OtaMagic.

To aid in OtaMagic the file pio/espupload.py has been updated to rename the platformio generated firmware.bin filename to the released firmware filename.

To save code space when using version 2.4.0 of the ESP8266/Arduino board manager some compile time parameters need to be removed. For Ardiuino IDE a change has been made to file arduino/version 2.4.0/platform.txt and for platformio a script pio/strip-floats.py is made available to be enabled in platformio.ini when compiling. When the correct installation steps are being performed as outlined in the menu on the right this will be implemented correctly.

Updated libraries

• TasmotaSerial-1.1.0
• PubSubClient library file PubSubClient.h define MQTT_MAX_PACKET_SIZE 1000

The use of a different language from English has been revisited due to incompatible JSON messages between Tasmota and external tools (#1473). This has resulted in major changes to the language files which now only translate the Web GUI and Logging messages. All JSON messages will now be in English.

The response from a HTPP command request will now be in plain JSON only. This allows for better integration with external tools. As a result the special Energy status message has been abandoned and is now provided as a Sensor status message. Useres may have to update their tools monitoring Energy values.

The Color2, Color3 and Color4 commands have been renamed to respectively Color3, Color4 and Color5 to make room for the new Color2 command.

The introduction of Device function pointers should make future integration of new devices easier.

New libraries have been added:

• Adafruit_BME680-1.0.5
• Adafruit_Sensor-1.0.2 + 2 commits
• TasmotaSerial-1.0.0
• TSL2561-Arduino-Library
