Sonoff-TASMOTA Updates

Theo has (as usual) been very busy with TASMOTA and has pushed out two releases in the last couple of weeks.  The first, at the very end of October (the “Halloween-een” 5.9.0 release) was a fairly massive update, with portions of the code being updated to follow Google’s C++ style guide as well as rewrites of some of the code to use command look-up tables and JavaScript.  In addition to those, there are seventy-odd other fixes, changes and additions.  Phew!  A couple of the notable items are:-

  • Addition of support for the Arilux AL-LC01 RGB LED controller.
  • Addition of support for the Magic Home RGBW LED controller.
  • Addition of support for the KMC 70011 Power Monitoring Smart Plug.
  • Addition of support for the VEML6070 I2C Ultra Violet sensor.
  • Addition of support for ‘inverted’ PWM.
  • Addition of support for the Luani HVIO (230v dual power control) board.
  • Addition of sea-level pressure calculation and a new ‘altitude’ command.
  • Addition of support for up to 8 relays (possible new product hint?).
  • Fixes for timezone and southern hemisphere STD/DST times.
  • Fix for a large flash erase issue.
  • Fix for ‘all-off’ issue when SaveState is inactive.
  • Fix for a pressure calculation issue with some BMP sensors.

…and lots more (check out the _releasenotes.ino file in the sonoff directory for the full listing).

The second release, 5.9.1, on the 7th of Nov, doesn’t have quite so many updates, but does add functionality to make addition of external sensors even easier and also adds support for the ADS1115 I2C AtoD chip, which a lot of people are going to find very useful.

That’s just a short round-up (I have no idea where Theo gets the time to do all of this magic …he must type at the speed of light) and, as already mentioned above, there are a lot more changes and fixes in there, so I’d recommend that you stroll over to GitHub and pull the latest version (it’s almost guaranteed to have even newer additions by the time you get there).

Sonoff-TASMOTA Updated to 5.8.0

Theo has just released version 5.8.0 of the Sonoff-TASMOTA package into the wild, with a fairly varied collection of additions, updates and fixes.

There are several changes related to WS2812 LED control, a fix for a watchdog timeout problem, as well as other fixes for MQTT, language support and Domoticz and addition of support for the Yunshan Wifi Relay and Witty Cloud.  The complete changelog is available here:- https://github.com/arendst/Sonoff-Tasmota/blob/master/sonoff/_releasenotes.ino.

Owen Duffy has a nice rundown on the pros and cons of the Yunshan WiFi Relay board on his blog (and it’s worth taking a look at some of his other ESP stuff, too).

An interesting new Sonoff (ITEAD) product on the way

Browsing through the wiki pages on the ITEAD site is always a good way to pass a few idle minutes and usually rewards the curious reader with interesting stuff (like schematics, for instance) which ITEAD are kind enough to publish for our edification.  Sonoff 433MHz to WiFi bridge, block diagramToday’s snippet was some information on what looks like an as-yet unannounced product, a WiFi to 433MHz gateway module.  The schematic shows this as an ESP8266-based unit, but there’s no separate flash memory chip that I can see and the block diagram refers to an ESP8285 (shame!).  There are both transmitter and receiver sections on the 433MHz side and it appears to use an EFM8BB1 “Busy Bee” 8-bit microcontroller to interface between the 433MHz RX/TX section and the ESP UART, with what looks like a slide switch (S2 on the diagram) to disconnect the Busy Bee to allow for programming of the ESP.  The device itself receives external power via a micro-USB socket.

Depending upon the price (and ITEAD prices are usually pretty reasonable) and the range of the 433MHz components, this could be a neat little device to have around. Front and back views (photo courtesy of ITEAD) It’s not just all of those older 433MHz switch modules that have been available for years, but also the slew of devices which just transmit (doorbells, weather stations, window interlocks, etc).  There does seem to be a four device limit on the number of remote 433MHz modules supported by the stock firmware though, according to the User’s Guide.

Update – ITEAD have just sent out a “Mid-Year Carnival Sale” promotion which features this unit (with the photo above) but, bizarrely for a sale, without a price.

Update 8th Aug 2017 – The main sales page is available on ITEAD’s site now and, for a time anyway, the unit is available at an introductory price of $9.90 (down from $12.90).  There are some clarifications of the details too, with the supported device limits being shown as “up to sixteen 433MHz RF devices” or “up to four 1-4 button 433MHz RF Remotes” (so basically 16 addressable channels).

As expected, Theo isn’t far behind and Sonoff-TASMOTA has had support for the 433MHz RF Bridge incorporated since the 5.5.0 version (released on July 30th), with further updates to the code added in v5.5.1.
