Ah - thanks very much, I missed that line. I will try it this evening.
When I initially tried the unofficial build, the dimmer worked, but then MQTT autodiscovery did not - I think it may be left commented out in the automatic builds - but I'll take a look

Thanks for the help

Thanks - getting there!
The precompiled binaries functioned, but did not have auto discovery MQTT enabled
My own build, with your extra #define line, got the power on/off section working fine along with auto discovery

At this point, the dimming works, but toggles on/off do not. I suspect there are some status messages that are not being sent/received as expected.

I think that is because I had not set:

#define TELE_ON_POWER true

from its default of false. Doing this has partially resolved the issue - there is now a STATE message on every power ON, but not one on POWER OFF. Still looking into why!

Domoticz requires a STATE message

maybe autodiscovery plugin issue (?) and maybe SetOption59 on helps,

I also use the dimmer with Domoticz and it works without autodiscovery,
(added the dimmer manually to Domoticz and inserted the Idx in Tasmota).

Hi there,

using QS-WiFi-D01-TRIAC since about 2 years with old tasmota an 0.3 script. Since about a year WebUI does reacts anymore, last week dimmer stops working completly (also LED goes defective). So i have reflashed tasmota to reanimate the dimmer, using the actual version. Usind the new v2.0a script, but the light changes with some delay on changes in the WebUI slider and when I dim below 9% the LED begans to flicker and the dimmer resets. So i set limit minimal dimming rangen by setting dlo to 10 and with it works well with the wall switch, but using the slider in the webUi dimvalues below 10 can still be set causing a reset of the dimmer.

So i have read the scripting manual und changed some parts in the script 2.0a:

Changed GPIO14 from pwr1 to relay1 (to get rid of the "old" slider)

replaced

'>E
; slider
;slid=Dimmer
;if chg[slid]>0
;then
; dim per slider
;if slid>0
;then
;dval=slid
;else
;pwrt=0
;endif
;endif

by

'>W
sl(%dlo% %dup% dval "%dlo%" "%dval%" "%dup%")

for new slider.

When Dimmer is off and a differend dval than before is choosen with the new slider, die dimmer goes directly on. To also get correct state of relay1 (must toogle to Power1 1) by adding the following to the script in ^F section in dval-if-loop:

if sw==0
then
=>Power1 1
endif

before:

if chg[dval]>0
then
=#snddim(dval)
=>Dimmer %dval%
endif

after change:

if chg[dval]>0
then
=#snddim(dval)
=>Dimmer %dval%
if sw==0
then
=>Power1 1
endif
endif

pros:

  • The new slider now shows the minimum an maximum values and the actual dimvalue an the LED and reacts much faster in changes in WebUi and can only moved in the ranges set in >D section.

cons:

  • none konwn yet

Best regards

Cool!

A possible downside is that by changing GPIO14 to Relay, the integration with Home assistant will not be automatic, as it will be considered as a simple switch, losing the dimmer functionality.
