Signify light strip set (LST001 and LST002)

[nepozs]

Signify light strip set (I don't know model now) - model/title will be edited

planned by @nepozs at an unknown date - only when I can borrow it, but

model LST001 is measured now by @CM000n #115

model LST002:

• currently abandoned by @wormiedk because of known problem with Shelly (zero values if power draw <~0.4W) Schedule of planned bulb/light measurements  #115
• currently abandoned by @Leatherface75 a because of similiar (to Shelly) problem with Tuya smartplug
• version with extension already measured by @bramstroker but data requires processing

Edit: both model finished (I don't know authors but probably @mariwing and @CM000n with support @bramstroker

I did actually measure LST002 some time ago. Did not include it in library because mine is extended (exactly 4 meters).
I cannot measure at 2 meters, because it is glued underneath my kitchen counter.
Would be nice if someone is able to measure this led strip at 2 meters.
Than we can compare to my measurements and also try to determine a multiply factor for each meter extension.

Power draw with extension should be something like (it is sufficient estimation I think):
Ptotal4=P2+P2+Psb
->
P2=(Ptotal4-Psb)/2

when 2 meters is used
Ptotal2=P2+Psb
->
Ptotal2=((Ptotal4-Psb)/2)+Psb=(Ptotal4+Psb)/2

where
P2 is power draw by 2m strip (and PWM part of driver dependent of power draw - it is linear estimation, but in this case enough)
Psb is standby power used by Zigbee part of driver
Ptotal2 - power draw by (driver + 2m stripe) so it is standard set
Ptotal4 - power draw by (driver + 4m stripe) it is set with extension

Of course this math is estimation and works properly only in case when driver isn't overloaded (but situation with overload isn't our problem, as I said somewhere before).

So data from measured 4m strip can be converted to 2m standard version (maybe it is temporary solution, but best for the moment).

BTW @Leatherface75 also have problem with small power draw, so not only Shelly plugs are affected, Tuya based also…

any help still needed? I have it and could measure without problems

All help is probably welcome if your powermeter works with low values.
