[wanted] power monitor/recorder


Recommended Posts

Other option is the Shelly EM. It runs wifi, upload via cloud so you van connect to it via app, website or log into the IP. Keeps log , hour, days Nd months and year and you export data. You can connect it with Grafana to. It runs 2 clamps and gets it's power from AC in your DB so it works Power Factor in to.

Let me ask him Right away. They very well priced. Standby.

Sincerely

Thanks. 

Do you have it on your main feed. How does it compare to the inverter readings. 
 

I have the efergy system and thought it was great until I installed the inverter. Now the efergy and inverter are way off. I was told it’s because the efergy does not take into account power factor. 
 

Was thinking of getting the victron et112 but this Shelly looks like a neater solution.

I'm running mine in my inverter DB that supply the house. It uses the L and N from your supply to give it power, so it keeps eye on AC volts and Power Factor. Clamp 1 I'm running in Main AC Breaker to my change over switches and Clamp 2 I'm running on my geyser to keep a eye there. I got my geyser interlock between eskom and the inverter so dump all my extra solar to the geyser then. 

What nice about the shelly EM is, it's got n relay/contactor control so jy kan switch stuff on via the Shelly EM. In the settings you can adjust so if you got n load on clamp one of say 3000w, and your inverter can only supply say 5000w, and a load of 3000w on clamp 2 starts up, then it will switch off the load on clamp 1 via the relay control and only switch on the load if the load on clamp 2 is gone again.

Does your inverter give you load power as well and how does it compare to the Shelly power readings.  
 

In terms of smart switches, I have more than 20 sonofs controlling various devices from heaters, geyser, lights, irrigation. I also have 5 efergy CT sensors on the efergy hub but it seems the efergy is not so accurate. 
 

What is the pricing of Shelly though. I sent a request to the shellyza email but haven’t received feedback. I really like the small form factor though.

Yes, my MLT gives that info and they really close. I use say about 98% the shelly EM info if i need to check. My day to day use lines up with my PV kwh and Battery kwh use. 

Best is to check here https://shop.shelly.cloud/shelly-em-50a-clamp-wifi-smart-home-automation-1#139 

The SA one you mail got a bit of story behind them, you can check on mybroadband. I see takealot stocks the Shelly 2.5 but it's way over price. You can import 2 for that price. SHELLY EU got n fix rate of €35 with DHL and then you stack the box full of shelly stuff. 

Maybe check on the forum if some poeple want and do a batch order then. 

So far I'm happy with mine and Energy and the other person that i imported with.

Okay thanks for the feedback. 
 

Local store got back to me. It’s R1800 plus R100 for shipping. Is that normal?

if yes, then it seems like a really expensive solution. 
let’s see if @Energycan get any better pricing.
