Can you confirm that the 5-12V version has all the settings that the 230V units have. The important setting I need confirmation on is that the power on state can also be set to RESUME   ON   or OFF.

How does one get to buy the switching off of loads when the grid is off if you are not an installer? Load reduction unit that is.

Hi, How are you?

Yes the Sonoff SV does have the thesame functionality as the 220 volt units. There is also offline alerting so the unit get's polled by the ewelink server every 5 minutes and you can get alerted.

We have removed the restriction you are welcome to buy a loadshedder. It was really just there in the interest of public safety and to prevent none electrician's blowing their inverter's. The Loadshedder is for load reduction and the scenes will shut down any sonoff device. Another recovery scene will then with small delay's turn devices back on. This helps with protecting appliances and lasting longer.

Everyone here is welcome to use the cupon code: "PowerForum10" it will give you 10% off. You guys have been Awesome 👌

Apologies just removing the link.

Hi. We need real-time total load monitoring for 41 individual flats. Preferably it would be possible to set alerts on individual loads, both draw and total usage when we're on battery. Are there Sonoff products that will make this possible? We will already be using Sonoff switches on DB boards so hoping for an easily-integrated system.

Thanks
Jesse

Hi

Sonoff's first move in that direction is the Smart Stackable Power Meter "SPM". I have attached a link to their site below. The biggest challenge is that the eWelink platform does not offer that amount of user administration and permissions level’s yet. The 4 relay module assuming one per unit closed off in its own DB would be close, i.e 1^st channel lights and critical loads like internet. 2^nd channel Kitchen plugs i.e. coffee machine, microwave kettle. 3^rd channel washing machine, tumbled dryers, irons. 4th channel geyser or none critical loads. They can be split in any preferences that suit the lifestyle. You could also add to that by subdividing below the SPM into individual circuits on sonoff dual R3 or POW units. That would give more control.

In saying all that would I feel comfortable with the solution or recommend it at this scale and manage it from ewelink not yet. It's close and it will get there. Home Assistant also ewelink VIP web interface is defiantly making go head way.

The ewelink cast is defiantly getting very close, where you can create individual dash boards per unit and pin protect them then just change the pin and lock the dash board.

Hi, I see that the HA is doing very well and moving at a nice speed with Sonoff., How are you finding your sonoff/HA working?

No issues on my end with the Sonoff kit - i have light switches, bulbs and gate / garage switches. The battery life on the door contact sensors isnt great though and will be swapping these out in due course with zigbee-based devices

Hi How are you?

I personally don’t like any battery powered devices that are a permanent fixture honestly, I would like to see a USB-C connector as an option especially for the PIR's.

Are you currently using the Wi-Fi ones?

The old RF ones where great on battery almost a year on a good battery (DW1-RF) they had no status so you could not tell if the door was open or closed and need to go through a RF bridge but I am still using then changed batteries 2 twice in 3 years.

The new DW2- WiFi ones depending on distance from router and how busy the network is, also battery quality and most importantly where its positioned. i.e inside of aluminium door frame which is sun facing that takes heat all day. The one makes a few weeks and battery is done. The same sensor on the other side of the house on a Woodend door frame that has a entrance way, much lower temperatures and the batteries are a lot happier. Over the six month mark of Duracell’s

RF Sensors (Low battery usage as it just a broadcast one way communications)

WiFi Sensors (High battery usage because of 2 way communications and TCP/IP)

ZigBee Sensors (Much better then WiFi and has 2 way communication but require a bridge)

If you have any questiopns please ask, we are here to share our experiances. :) 

 

  

Have been using the DW2 wifi ones and you are correct - a few weeks and time to pop in a new battery. They are all close to an AP so range-anxiety is not an issue. 

Hi

There is also a trick to putting the batteries in and it should not have to be this way and we have reported it to the manufactures a few time and still are.

There are 2 versions of the DW2-Wifi and one was with a MN27 and the other is with 2xAAA in both cases the edges of the battery holder are not been bevelled enough and is quiet sharp and that sometimes depending on the battery manufacture cuts through the battery coating enough to short it. I defiantly recommend the Duracell batteries and when inserting the battery you can use recipe any from your wallet, insert small piece between edge and battery only on the side and then push in the second battery. Again it should not have to be this way.

Good afternoon. I am interested in the Sonoff Loadshedder but i need an data sheet and wiring diagram. I would like to see if i can integrate these systems when installing smaller type inverter and battery by reducing load automatically during loadshedding. I would like to be able to offer this option to my clients as a battery saving resort.

1. Switching speed on loads when loadshedding hits.

2. I was looking at the Loadshedder Bundle that i could switch pool pumps and geysers please allaborate on high current load switching.

3. For visual status the Smart Colour bulb how does this work.

Thanks in advance @TaliaB

I recently purchased one of the 25A (5500W) Sonoff switches for my aircons. I think that is large enough for most pool pumps and geysers?

 

As for the switching speed, well, it still takes a bit of time. If you are worried about the battery not handling the load then that is a concern and one I do not think will be resolve with these sonoff switches as the switching would not happen that quickly.

Even with my light switches, when I turn it on/off via my phone there can be a slight delay. If you just want to the devices to turn off shortly after loadshedding has started then it would work well - shortly being within a few seconds... Although I plan on using Home Assistant to monitor grid status from the inverter and then do the switching - no loadshedder for me.

Thanks @PsyCLowni am not familiar with the Sonoff smart switches but your info helps much appreciated 

Is the web portal only available to subscribed users?

Hi I Am running a loadshedder kit along with 2xPOW320D the loadshedder works well in turning the units on and off when loadshedding hits however the challenge i am having is having the POW's power on state follow the schedules programmed to each. is it possible to have the the units turn on and off according to the loadshedder status only within the scheduled times ?

Hi

The reason this happens is because the schedules are locally based and "Last command is true" which applies. So if a Schedule runs after LoadShedder has turn off the device it will turn it on.

The solution is to  run you schedules from scenes which when LoadShedder is "ON" then you turn of the scene automatically with in the Load Sheading scene and when Load Shedder is OFF you let the Recovery Scene turn them back on automatically.

It works very well, we have this setup in over 2000 sites now and the only challenges where network issues which the Sonoff iHost has resolved.

Hope this helps and if you have any questions please feel free to contact us.
