Tasmota: BH1750 - Error on command

[stehof2]

PROBLEM DESCRIPTION

Hi,

First my setup:

• NodeMCU v3
• BH1750 light sensor
• Tasmota 8.4.0 (tasmota-sensor.bin)

I’m having an issue when I try to command an option, this feature is quite new, it is from issue #8016 https://github.com/arendst/Tasmota/issues/8016

When I command Sensor10 1 to change the resolution, I get response Command:error without further explanation what went wrong.

This is the output from the console:
22:30:43 CMD: Sensor10 1
22:30:43 SRC: WebConsole from 192.168.0.147
22:30:43 CMD: Group 0, Index 10, Command "SENSOR", Data "1"
22:30:43 MQT: stat/LuxKeuken/RESULT = {"Command":"Error"}
22:30:58 WIF: Checking connection...

Same result when I try to set the option over a http request as from the console.

Any idea why this isn’t working for me?

you must use Bh1750Resolution1 Command:

Bh1750Resolution1 0..2 - Set BH1750 1 resolution mode

[stehof2]

Bh1750Resolution1

Thanks, that seems to do the trick, how did you find out, couldn’t find anything on it in the documentation beside of Sensor10?

And do you also know argument for setting the measurement time? Tried several combination with Bh1750 and Measurement1, MeasurementTime1 but that’s not working :(

[device111]

Ok, seems there is not yet in the docs.

Here are the commands from source:

• Bh1750Resolution1 0..2 - Set BH1750 1 resolution mode
• Bh1750Resolution2 0..2 - Set BH1750 2 resolution mode
• Bh1750MTime1 30..255 - Set BH1750 1 MT register
• Bh1750MTime2 30..255 - Set BH1750 2 MT register

• Bh1750Resolution2 0..2 - Set BH1750 2 resolution mode
• Bh1750MTime1 30..255 - Set BH1750 1 MT register
• Bh1750MTime2 30..255 - Set BH1750 2 MT register

Thanks, just what I was looking for! It is working now 👍
