September 2, 20205 yr I'm looking for a single phase power monitor that monitors voltage too. Single phase is fine Bonus if it is WiFi capable, but as long as it can log at least 5s apart Im good
September 2, 20205 yr good option imo is the ET112 from Victron, also known as Carlo Gavazzi. Although not Wi-Fi, but works well for most R
September 2, 20205 yr 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.
September 2, 20205 yr Also running the Shelly ! They great. A good Freind of mine imports them. Shout if you need a unit. Sincerely Jay
September 2, 20205 yr Just now, Vassen said: What do they cost? Let me ask him Right away. They very well priced. Standby. Sincerely Jay

September 3, 20205 yr 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.

September 3, 20205 yr 5 hours ago, Vassen said: 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.
December 30, 20205 yr @Gerlach@PaBz0r Still interested in Shelly's? Looking to get few guys together to import some and save on shipping.... Let me know if interested.

Let me know if interested. Might also be interested. My old monitor is done, and the online portal also got shut down so need a new monitor...
January 19, 20215 yr Posted a group buy thread with cut off dates when I'm going to order if anyone wants to club in. I'm going to order for myself in anyway, so let me know. Shelly Group buy, direct import - Group Buys - Power Forum - Renewable Energy Discussion @Singh GP @Vassen @PaBz0r @langou
January 27, 20215 yr Still planning to order end of this week... If there's still someone that wants some shelly stuff...
January 27, 20215 yr I'm torn with the monitoring... I just want something neat and tidy in the DB that doesn't have cables all over the show. I've checked OEM emonTx, Iotawatt, etc. They need extra plug in adapters. The Shelly looks cool but I don't want the relay part of it. I'm not interested in switching. I wish they made a Shelly PM with no switching. These "63A 1P Smart Circuit Breaker with monitoring - eWelink" look interesting but they like R700 each. But then I think there will be a lot of interference in that DB with so many things trying to connect to WIFI. I assume it would be the same with lots of Shelly's in the there too. CBI Nanoview might just be the neatest solution. And then forgo the cloud monitoring.

As far as I could see the Shelly EM for DB board monitoring does have one contactor control switching possibility but you don't need to use it to measure power. You use p1 and p2 to connect your clamps, so you can measure two channels, which you clamp over the wires you want to measure. So no switching done on the channel you are monitoring. The contactor control is handy to have, but is a seperate function to the power monitoring. I will still keep my current cost power monitor to visually see what is happening... but will use the shelly for the accurate logging. The Shelly PM with the relay is for single smaller appliances and not for the whole house application.
October 12, 20223 yr Old thread resuscitation, but is anybody still bringing in Shelly EM's? I need one.
October 13, 20223 yr @p_i,I no longer import Shelly on a B2B basis, had too many people incorrectly wiring their items, popping it. Then they were completely oblivious when the item is half blown away or melted away, "I have no idea how it broke" and demanded a refund. Nology is the currently the only B2B importer and distributor, however they don't bring in the Shelly EM's. I actually had a conversation with them yesterday morning, asking when will they bring it in, but they said the demand for it was too low. I called BS on it, but anyway its up to them. Your best bet is to wait for black friday and then order a shelly EM + clamps from shelly EU site. 25 November 2022 and tt takes like 3 days with DHL. cc: @Energy-Jason Edited October 13, 20223 yr by jeeva
