Change SONOFF SV to ISOLATED mode

[@michaeleden5520]

Do you have a part number or a link for that 2 pin connector you used for the power supply?

[@DIYGEEKTEXAS]

I used a generic 2 pin connector cable: amzn.to/3dM8Mwl -or- you can but any female-female / female-male cables like these: amzn.to/3hiBrvc

[@leglessinoz]

It's just a couple of female DuPont connectors in a 2-pin shell.

Thank you for this video...I know it was a long time ago, but it worked perfectly for me to use the SV with my gas fireplace.

[@DIYGEEKTEXAS]

@Tarun Chachra Gas fireplace is a great idea of use for the SV sonoff. Great idea! Thanks

[@nothingpoopoo]

I want to do the exact same with my fire place. I have sonoff but not sure how I should wire it. The igniter uses 4AA batteries . How’s you do it?!?

3:56 Fun Fact. The regulator used in this unit (According to the datasheet) is only capable of 23v with a surge of 26v 5:02 The two pin headers (in between the resistors you removed), is actually a jumper to join the tracks for it to be used as an isolated relay. Edit: The jumper in between the 2 resistors is for passing power from the 2 pin header just to the right of it and not a bridge for the relay (Apologies, just wanted to clear up any misinformation about the connections to the unit)

[@DIYGEEKTEXAS]

Thank You for your comment and facts. Sorry I still don't understand, do you mean by removing the resistor, the Sonoff can NO longer be in isolated mode?

[@-Gadget-]

@@DIYGEEKTEXAS On closer inspection it seems that the jumper is meant to send power out of the input on the other 2 pin header. However, you could just solder one wire on the output of the board and one wire on the input side of the board to utilise the relay terminals once the 2 resistors have been removed. The circuit diagram for this unit is not the best, so I miss read what the jumper does by the looks of things. I will trace the printed circuit for these contacts tomorrow or Tuesday when mine gets delivered (hopefully) and just make sure. Anyway, thanks for the information in your video, and here's to hoping I can get one of the units installed onto my gate motor in the very near future 👍🏻

@@DIYGEEKTEXAS Apologies for the delay in reply. I have installed this module on the gate motor, works like a charm. I did go a bit overboard with the other IO ports, so I added a beam just incase there is a vehicle still in the gates way as well as the Reed switch for open/closed status, and also a "Door Bell" at the front gate on another spare IO port, which then wirelessly sends a signal to the unit I have in the kitchen for the doorbell chime (best addition I've made thus far, because now the doorbell never requires batteries as well as the chime, as I have these powered directly from my solar system). Thanks again for the info you put forward in your video, as it gave me some good ideas, as can be seen from this tedious post lol. 👍🏻👍🏻👍🏻 Edit. Ps. Quite correct, removing the resistors "still" allows you to use the unit in isolated mode

Thank you for this video!!

Not quite sure why you would need to convert the SV to isolation mode. Instead of feeding input voltage into the input positive and input negative terminals, what If you took the two wires you intend to use in isolation mode, and connected one to the input positive terminal and the other to the output positive terminal, wouldn't you have accomplished the same thing without modifying the switch?

[@JohnMasseria]

Could it be safer in the sense that without isolation the input voltage powering the Sonoff will always be present on the input positive terminal?

[@Dunkeej]

I am having problems controlling the gate after installing sonoff in isolated mode. the range of the controller has been reduced and only works within 2 meters of the gate. Do you have any idea?

[@thanasispantazis9464]

Hello can this module start a pc ? Or Can you help me how to do this without wake on lan ? Any ideas ?

[@DIYGEEKTEXAS]

Not the SV, because SV means safe voltage (low voltage - below 50v), you need to buy the regular Sonoff, that one you can use to turn PC on/off

[@thanasispantazis9464]

@@DIYGEEKTEXAS I just need the relay to close the circuit from motherboard' s jumper through internet outside home.

[@phoen-gr7914]

Yes you can, but you will need an arduino too , you use the dry contact from this SV as shown on video to let the arduino know that you want to power up or shut down a pc , then program the arduino to close a relay for 400ms to pc power button, each time you change the state in sonoff. (note. voltages and gnd from arduino/sonoff must be isolated from pc. Greetings from Greece btw

[@noisysprings]

Yes it can. Just connect in parallel to pc's on button wire and set mode on sonoff for non latching.

[@MrWhiteKawa636]

@@noisysprings how to connect exactly? any if this photo's explains it, which? Thank you!

[@milespraza3374]

Thanks so much! Awesome instructions.. worked like a charm

[@musiclovertv67]

Can i use 30 Watts solar panel and 12volts battery here answer please

[@Joeljvr]

can it be used on A/C switch to turn it on/off?

[@DIYGEEKTEXAS]

Not the SV version (sv stands for safe voltage), but you can buy the Sonoff Basic, that version is exactly for the 110v A/C. Here is a link to Sonoff Basic at Amazon: amzn.to/2M6NOgV

[@phoen-gr7914]

www.itead.cc/wiki/File:Sonoff_SV_mode.jpg see you can use up to 250v in isolated mode but you may have problems with the current, for loads as an ac you may need second relay, plus its not practical because you will never know the temperature of your room and its very easy to end up with messy wiring, fire or broken ac electronics. There is a Sonoff device that may display room temperature (www.amazon.com/Sonoff-Temperature-Humidity-Controller-Appliances/dp/B075FSHKQ5/ref=sr_1_2?keywords=sonoff+temperature&qid=1548141191&sr=8-2) . Most easy way is 1. to check if there is a wifi module for your ac (many brands have wifi modules offered as an extra upgrade). 2. if wifi module doesn't exist then you may search for an Infrared wifi controller like (www.aliexpress.com/item/WIFI-Universal-A-C-controller-Air-Conditioner-air-conditioning-remote-control-CHUNGHOP-K-380EW/32705504444.html?spm=a2g0v.10010108.1000001.7.2ff01b7dl8hOdW) . 3. Sonoff TH16 is always a good option, but its 3rd in list because i dont like the abrupt power loss in inverter ac, in long-term use may cause damage to electronics or pump.

[@mariustw1]

I have a problem, I use SV version, I connected a mini water pump (DC3-12V RS-360SH) I feed with 12v and when I start, the Sonoff reboots (it happens the same when you short-circuit outpins). My Sonoff works perfectly with other devices. Please help, thank you

[@DIYGEEKTEXAS]

If you are feeding 12V, you do not need to follow this video, because this video is to convert your Sonoff to isolated mode, which means it will convert to a short-circuit switch (like a relay). Does that make sense?

[@mr.breugelmans]

Use the regular sonoff mini Where you cut one connecties and solderen a wire, that's 5 min. work

[@the1spyderryder]

The term is not "short out" but is to "close the contacts". Why dont you unsolder the resister and do it right?

[@adilsonms]

Estou tendo problemas com o controle do portão depois que instalei o sonoff no modo isolado. o alcance do controle reduziu e só funciona a uns 2 metros do portão. tem alguma idéia?

[@Dunkeej]

você resolveu o problema?

[@pauluskusuma]

Just use sonoff re5v1c mate... It's designed to do the inching...

[@h4plugins334]

JUST DESOLDER IT!!!!!!!!!!!!!!!!!!!!!

[@KeyBored101]

Lol, Dr. Zzzs also did that
