Reducing Power Consumption on ELIVCO LSPA9 Smartplug with LN882H Chipset

Hi all,

I have an ELIVCO LSPA9 smartplug with chipset LN882H. I followed the instructions and flashed with version 1.17.701. Also calibrated the BL0937.

I made some consumption tests using a reliable Belkin device.

Unaltered Blitzwolf SHP6: OFF it consumes less than 0.5W and ON 0.6W to 0.7W.

Now the ELIVCO LSPA9, OFF it consumes 0.7W to 0.8W and ON 0.9W to 1W!

How can we lower this consumption?
I don't need the web server always running. Also, the skipped value in energy total is always increasing?

I just need the switch control on home assistant, lower the consumption and maybe the heat.

Thank you for all the inputs.

Hi. Are you using the powersave command in your autoexec.bat on the LN882H?

So, for your setup powersave 1 should be used in the autoexec.bat

I was not using autoexec.bat with PowerSave 1.

Thank you so much for this tip

Now the ELIVCO LSPA9 consumption:
OFF - it consumes around 0.5W
ON - 0.7W to 0.8W.

Also, the heat reduced.

What are the impacts of using PowerSave 2 on this device?

it breaks BL0937 power measurement. see evolution of additional powersave options developed by @max4elektroda in this topic leading up to this post: https://www.elektroda.com/rtvforum/topic4028087-180.html#21064629
