This has all the devices you need prefixed with ‘Connect Series -‘ when you go to add them.
You want to add the WiFi link first, add its ipaddress in config, then check logs
Does anyone have issues with power metering?
I’m turning on the hairdryer which is 2000W and on LightwaveRF socket shows only 1100W.
I have double-checked with my mains metering which is KNX and very accurate and it spikes from 1500W to 3500W power usage.
Any ideas?
There is a voltage reset channel, add it, turn it on/off, then restart the socket (kill power for 10 secs).
This sorted all mine out
Don’t think I broke it in latest versions. I had a few all messed up on the power and this basically resets the power metering chip so it reinitialises (found it by pure chance when developing )
Seems I have issues with all sockets. Power metering is not accurate. Another example is my rack, I have a ups that is using 305W (I can see that in the web gui) and the socket shows usage of 200W.
I’ll send them an email
I tried what Dave suggested but still the same
The devices are to be used as an indicator of power usage.
The energy monitoring function is for indicative purposes only, when the measured load contains capacitive or inductive components (most switch mode power supplies), it does not have a high accuracy."
You should be able to get/work out the power factor for inductive/capacitive loads and have some rules going. Think this is probably the case with mine too but never actually checked.
The hair dryer should be accurate though as this is resistive…
I try and get some time to check mine over the weekend
@pentiumdb does seem to be out (see below - Kettle) which makes it pretty pointless. I’ll do some more testing against my clamp meter and energy monitor over the weekend. Pee’d me off tbh as was one of the reasons I chose LW.
I’ll calculate against the voltage reading over the weekend too as it may be that reads incorrect and therefore power is incorrect
I’ve just looked through all of their spec sheets / sales literature. There is nothing in there to specify what you have quoted from them above. It clearly states ‘monitor energy usage’. Once I’ve got enough data I’ll see if I can find any pattern etc. If I can correct it through the binding I will, but I’m certainly going to bring it up with them as to me this is not acceptable.
My kettle is a resistive load so from what they are saying this should be accurate (I understand capacitive/inductive won’t be) - And I would expect this to be accurate to at most 5%
I’m a fridge guy so yeah electrics are my thing too
Still… 3500 / 240 (voltage normally there or there abouts) = 14.58 amp… thats not right.
and even if the voltage is lower, amperage is going to increase. #InvestigationRequired
