AC energy monitor

[blackrose]

My old owl energy monitor has stopped working - the remote sensor is no longer sending a signal to the display.

 

What's a good alternative with a decent display to see how many kW of power you're using at any one time? That's all I need it for. I don't need any of the other features.

 

I found that the Owl goes through so many batteries that it would negate any cost savings made though the use of the meter. However I'm not really using it to save energy, but just to avoid tripping any breakers.

Sonoff arent bad.

I have a 20amp Sonoff on the van. Bit fiddly to set up but once done you can read it from anywhere provided it has WiFi.

I was thinking about something with a clamp type sensor rather than something I have to physically connect to the mains ring. Does the Sonoff need to be connected?

I would think so. Furthermore, it's a Sonoff a bitch to do so if you aren't electrically compatable.

Thanks, I just need something simple to install that gives me a rough idea of how much mains is being used while I'm onboard. I don't need it to have WiFi or whatever.  I'm have a look on eBay for something cheap.

What's your setup? Inverter/shunt/system controller? You may be able to do it in software already.

Can you not use a plug in power meter such as this?
