High Jan,
you were able to show the actual version number of Tasmota without the leading “v”. Could you share your solution?

sure. here are the items in the items file:

String SonoffCurrentVersion "Sonoff fw version on public server [%s]" 
		{ mqtt="<[maddox:sonoff-version:state:REGEX(.*?(\\d+\\.\\d+\\.\\d+).*)]" }

String Sonoff1LocalVersion "Sonoff #1 running fw version [%s]" 
		{ mqtt="<[mosquitto:tele/sonoff1/INFO1:state:JSONPATH($.Version)], 
				<[mosquitto:stat/sonoff1/STATUS2:state:JSONPATH($.StatusFWR.Version)]" }

Thanks for this answer.
However, if I’m not mistaken you are using a seperate mqtt Server to get the version info of Tasmota. How did you set that up? I’m actually using the http-binding way to get the Version number, but using that way i get “v5.12.0”.

exactly, i used this post to set it up. It is an external mqtt broker.

Thanks, I must have overlooked that one (this thread got rather long).

A note to all that would like to flash a sonoff without soldering (like me).
Trying to hold the pins into the sonoff while pushing down the button didn’t work that well. The long pushbutton, without the covering, is really unstable and I broke two of my switches while trying to come into the flash mode.
However when sticking the pins into the board and covering the switch with its cover not only the use of the pushbutton was much easier, the conections where also held quite stable (for my last remaining 4 switches I had no false try!)
Some pictures:

Now I only need to find a way to get into the flash mode on the switches with a broken push-button (the small metall foil is gone as well :weary:).

nice one. i also have a similar cable only for flashing sonoffs.

Thanks very much for the helpful tip. My ftdi programmer arrives tomorrow. I’m so glad I won’t need to solder. Shame about losing the ability to OTA update.

I ordered a couple of those switches, basic, double and TH versions. The double and TH versions were still able to OTA flashed!

Hi all,

I have ordered 100 Pogo Pins from China for flashing some time ago and i definetely won’t need all of them.
So if someone is interested, i can give away some of them for free.
I would suggest packages of 10 Pins.

I would send them over on postal way, but only within germany. (Sorry)
If you would like to take the postal charge that would be fine but not necessary.

So if you want some of them, just message me.
There’s no reason to hide them here in my cabinet, when i won’t need them all anyways.

Hi guys a msg from a newbie on OpenHAB with some SonOffs, thanks for all these excellent hints, tips and inspiration. Specific in msg #84.

I also tried the other variant but was Not sure how often the maddox MQTT statement (#515) was “pushed” till I realised that #126 already mentioned adding an entry in mqtt.cfg :slight_smile:. However must still made a mistake or missing something because the result is:
Sonoff fw version on public server REGEX(.?(\d+.\d+.\d+).)
(not a real issue)

I also want to use the Sonoff icons from @ThomDietrich but so far i only searched them on the wrong places :confused:, Already published?

To end this story I have 2 Sonoff basic (a POW and a TH16) but only one of them gives an error on the “queryFW” command. Think this Sonoff basic works for the rest as expected:

Any ideas?

We would have more ideas if you would post the setup used. Like the rule, the items…

I’m getting an error when trying to flash…

I used Platformio to flash tasmota on my Sonoff and it worked so much better. I’m not sure if this helps??

Hi Jürgen, thanks your offer to take a look at my small problem, small because I likely can life without it (who cares the prefix “V”) or just ignore the warning. I start with my second problem because I found some additional info in the log:

2018-04-02 21:28:26.650 [WARN ] [.core.transform.TransformationHelper] - Cannot get service reference for transformation service of type REGEX
2018-04-02 21:28:26.699 [WARN ] [.core.transform.TransformationHelper] - Cannot get service reference for transformation service of type REGEX    ==> /var/log/openhab2/events.log <==
2018-04-02 21:28:26.717 [vent.ItemStateChangedEvent] - SonoffCurrentVersion changed from NULL to REGEX(.*?(\d+\.\d+\.\d+).*)

Think i still forgot something is this a transform .map file or something completely else? I cut & paste #126 and even did not to forget to add the line in mqtt.cfg :slight_smile:

For the first problem both sonoff basic are using the same settings; it looks like that one of the Sonoff basic sends an erroneous STATUS2 response but I do not see any visual difference:

{"StatusFWR":{"Version":"5.12.0","BuildDateTime":"2018-02-09T14:54:51","Boot":6,"Core":"2_3_0","SDK":"1.5.3(aec24ac9)"}} //sonoff1

This is the only error I see using this Sonoff. Here are the requested details, again ordinary cut & paste from this topic.

In order to display the currently used firmware I have:

String Sonoff_Version "Sonoff Version: [%s]" <sonoff_basic> { mqtt="<[opusMQTT:stat/sonoff_TH/STATUS2:state:JSONPATH($.StatusFWR.Version)]"}

Other then that I don’t understand what your problem is.

That line also works for me, Another method (SonoffCurrentVersion) is pretending to give a version without the prefix “V”, this one does not work yet, though not very important, perhaps @AndrewZ can give some info what is still missing.

The other problem is just:
[ERROR] [.mqtt.internal.MqttMessageSubscriber] - Error processing MQTT message.
If I understand it correctly the Sonoff basic is sending an incorrect MQTT message
The lights still goes out (and on) so …

Thanks for looking into my problem

IMHO the “v” only shows when requesting the the version published, not the actually used one. My solution the show this version without the “v” is Here.

I need some help with my sonoff devices. At the time I have 4 (Touch, 4CH, Basic, TH16). All of these are flashed with Tasmota. I use MQTT between OpenHAB and Tasmota.
My problem is, that always if I open the Web-Interface of one of the devices, the sonoff stops to work (after 5 to 10 seconds). After that I have to restart the device by power off. If i dont open the Web-Interface everything works fine.

I only use MQTT and WIFI. The MQTT Server is Mosquitto next to Openhabian. Without security.

My MQTT.cfg: (the rest is commented out)

# URL to the MQTT broker, e.g. tcp://localhost:1883 or ssl://localhost:8883

Did I do something wrong while flashing? At the moment I use Tasmota 5.12. Maybe a problem with the memory? If I disable MQTT all works fine also.
It would be also o.k. to disable the Web-Interface, but i think that´s not the way. :sweat_smile:

Here is my user.config.h

After the flashing progress i configure the MQTT settings.

In the screenshots you use Tasmota V.5.10 not 5.12.
Try latest build, and in userconfig.h disable not used features.
-> Hass and Domoticz
A good idea too is to fill in your wifi settings…
