Shelly 2.5 - dual channel wifi relay with roller shutter mode 

Came here to find how to wire 2 sockets, wasn't disappointed. I know I'm a bit late to the party but I didn't even knew shelly existed when I built my home. This is a must have for every smart home out there.

Szia Csongor! This video is just perfect! I was struggling with looking shorter booring Shelly videos to get usefull information without success. This nearly 30 minutes just flew away. :) Thanks for it!

Mate, this is by far and i mean by faaaaar the best video for Shelly relays. Thankyou.

Köszönöjük szépen! Nagyon hasznos, és rendkívül érthető. Még angolul is. Már rendeltem is egyet. 😀

Hands down the best explanation of the wiring, thank you!!!

I've been trying to figure out what these diagrams mean for days now! You presented it in a super simple way that I could follow! I'm looking forward to more videos!

Great review! I already have several Shelly's in use. Only a 2.5 I still miss for my sunshade.

Thank you for taking the time to explain the wiring and using diagrams

congratulation very good video explanation about Shelly 2.5 Thank you to help on this issue!

Thank you for the clear and concise wiring diagram! I had planned to use just regular switches but your example with momentary switches won me over. Thanks! (subscribed).

Great review. You answered all the questions I had about the use of external switches.

Excellent video, in a limited time a lot of great information!

Hello Csongor :) Thank you for this great tutorial, I really appreciate it :)

Excellent narrative I’ve been looking for such a device for our own roller shutters, thank you so much.

Excellent video! Thanks a lot for making it.

Great video. Perfect for those that are trying "do" things with shelly. Thanks for that

Perfect video, thanks a lot for the detailed explanation. Keep up the good work!

Great video very simple and very informative. Thank you

Excellent video!

Thank you for this very clear and very complete review!

Thanks for an excellent video. I have been looking for a way to operate a linear actuator and this looks like it is perfect. Thanks!

Nice video! My shelly 2.5 always reads 0w on load, even when I measure 135W from the multimeter... I have around 50~60 sonoff devices all online and 100% working and they are cheap and good, I bought my first shelly and it hasn't been a pleasent experience.

thanks for this very clear and step wise instruction vdo. hope you make more like these. probably for shelly dimmer?

Hi I was wondering if you'd be able to help with a wiring diagram. I'm looking to control a valve that is operated by a dpdt switch. The valve has two wires and opens/closes by reversing the polarity of the switch. Would I be able to do this with the shelly 2.5 via wifi and also still use the physical switch? Any help or diagram would be great!

Simply BRAVO ! Perfect explained !! Thanks !!!!!

Well presented vid. Thank you. I’d like to see you do a Shelly Dimmer vid.

Splitting the L-wire on the 2 L-inputs (4:35) shouldn't be necessary, they're both connected via a bus bar internally. They sometimes advise it because the screw terminals can hold less load than the bar, but you'll still be powering both outputs from the same cable (probably with a Wago in front)

I have a 2-speed whole house exhaust fan w/ 4 wires: Neutral, Load, Hi speed (6.5A), Lo speed (3A). I was hoping to wire it like a curtain motor (with close as low speed, open as high speed, and both speeds unable to be on simultaneously). I tried this with a Sonoff DualR3, testing it at first via 2 lights. For each light to stay on indefinitely (unlike a curtain motor), I didn't "calibrate" the motor as the app requested. Once I did that, the DualR3 worked as I had hoped. But after wiring it to the actual fan motor, when selecting either Hi or Lo speed it would start for 1/2 second and then go back to Off. I later found out that this is because the Sonoff, while rated for 15A, will only accept a 1A motor load. Does the Shelly have such limitations as well (motor timer and load limits), or could it possibly work for my situation?

Hi Good presentation .. Does the Shelly 2.5 need the neutral wired to the unit ?

i was hoping to find here some tips on how to actually fit this behind a switch with all the stiff cables and 3-4 wago connectors. i was also considering to install it behind the shutter outside, but i don't have enough wires to connect the switches. i barely managed to fit the shelly i3s behind the switches, where i actually used double switch boxes - one of them housing the shelly and the other the wago connectors. i am quite convinced that it is impossible to actually install this in a regular switch box. but any tips are welcome.

Szia Csongor, köszönöm a videókat, nagyon sok segítséget adnak. Ez alapján kötöttem be a Shelly 2.5-et két egymás melletti konnektorba. Ha és MQTT mellett használom. Kicsit magasnak tűnik a hőmérséklet, 55 C kikapcsolt , 1 relével 65 C , kettővel 70 C, mennyire kell aggódni emiatt ? Köszönöm

I just wired my Shelly 2.5 but for some reason I have power coming out of both my SW and can't control the lights with the physical switch at all. Any reason why?

Szia Csongor! Igazán szuper a kisfilmed. Pergola lemezeit szeretném vezérelni ezzel a megoldással, csak nekem egyenáramú motorom van. Megoldható így is?

Hi, if the shelly crash (like burn) the manual botons keeps working? other qustion... can we open\close all shelly at the same time? tks

Hello Csongor! I am looking for a similar smart (controllable trough wifi with smartphone) temperature controller relay like Sonoff TH10 but with two controlled circuits. When below MIN then it will turn ON curcuit "A" (heating), then turns OFF when higher than MIN but below MAX. If higher than MAX then turns ON cicruit "B" (cooling). I do the same now with STC-1000 but it is not smart, need to change the temperature on the spot. Is it manageable with this Shelly 2.5? Do you know a cheap thermal controller (nothing special, only indoor use) shelly can operate with? Smartpid m5 mini is too expensive for me, costs 4x more than this unit. I hope you can help me out with this issue. :)

Hi Csongor, can you comment on the use of the Shelly 2.5 in Shuttermode with a double switch (two separate buttons, one for up and one for down) that actually are switches, locking in the switched position, not like the spring loaded push buttons you use in the video. These switches are common here in Germany for blinds. Thanks Rainer

I think most US houses use solid copper wiring. does the wiring fit in the screw post on the shelly?

Hi, can I use DIN version Shelly pro 2 for electric blinds (roller shutter) too?

@csongorvarga Thanks for sharing! a question, if i have a 3 gang switch plate, is there any shelley product? or what do you suggest ? i need 1 shelly 2.5 and 1 shelley 1? for 3 gangs? thanks!

Great stuff - Is the neutral wire required for this model? I don't have any neutral wires in my house although some switches are on double walls so it can be done if required however this isn't an option for the ones on the internal walls. I have 4 roller shutter motors and some wall switches (some single and some double & quad) for lighting (will need a dimmer for a couple of these) which I am planning to automate. Which models would you recommend please?

why switch is not working , i connect my switch one way to the shelly but is not workin

Köszönöm ;)

I am interested in this device but does it work with low voltage DC battery shutters ?

Congratulations on a helpful review. How can I get feedback on the condition of the blinds, whether it is open or closed. I think on this principle to drive a pair of garage doors. The garage door automation has a magnetic sensor that sends a status signal, but how do I connect it to the relay?

What is the manufacturer/model of the momentary switch you use on your desktop model? I can find momentary Leviton switches (in US) but they appear to be a rocker that indicates up/on, down/off.

Thanks for this. I am thinking of replacing some hopeless switches to my roof vent. They were supposed to have a thermostat and open/close relative to the room temperature and a rain sensor to close the vent when it rains. The thermostat is just terrible and does not perform as I would hope (opening and closing at the wrong temperatures) but the rain sensor is a good story. Can you think of any way to reuse the rain sensor in the wiring of a Shelley 2.5 in roller shutter mode? I was going to write my own home automation to use my heating thermostat to control via wifi when I open or close but was hoping to still auto-close when it rains! Any thoughts?

where did you get the momentary switches

How can you use this Shelly 2.5 to drive a 12v actuator? It's like a shutter (ON - OFF - REVERSE) but needs to be 12v. Can I use a 24v to 12v adapter? Is the wiring the same as shown for the shutter, only without the shutter switch?

Thank you very much! What if I have a remote control for the shutter?

why the two L have to be connected and not only one of them?

hello, do you know a is it possible to make a scene that the trigger is the voltage value consumed?

Is there a setting, where you can choose if only one switch will be active? . So if sw1 is active and you what sw2 to be active. Then sw1 has to be switched off first, before sw2 can be active. I want to use this shelly with a switch who has 3 states , actually 3 speeds for a fan. Sw1 sw2 0 0 speed low 1 0 speed mid 0 1 speed high 1 1 can not be made

I love the detail in your videos. Very well done. I have a question for Csongor or for anyone that can answer it. I'd love to implement these smart relays in my sheds at my house in New England. If you know New England weather it can get pretty cold during the winter and very hot during the summer. Has anyone used these relays outside in harsh temps and how do they respond in real world. I know that they have operating temps of O degrees C / 40 degrees C. Is there a way to keep the relays warm/cool if it's going to be implemented outside?

Looking at the button types, I see the "Toggle Switch". How would that one work? Would that be a single-switch rolling shutter setup?

1:33 AM how did I get here???? (Awesome stuff btw)

Is the Shelly 2.5 - dual channel can control two shutter rollers? what is the meaning of dual channel in that case? thanks

Nice video! Is it possible to install this device with a double switch which already controls 2 bulbs? Thanks.

Very good explanation ! I'm just wondering, if this shelly is capable to fulfill the following scenario: I have 2 simple 2-way switches (so just 2 terminals per switch), and I want to use the 2 switches to turn on an off a light from either switch. Unfortunatly these switches are not momentary switches and these can't be changed. So in fact I just need only one output, but both inputs (one at either switch). The logic must be something like XOR: S1 ON, S2 OFF: Output ON S1 OFF, S2 ON: Output ON S1 ON, S2 ON: Output OFF S1 OFF, S2 OFF: Output OFF Would this be possible? Cheers, Georg

redony mozgatasi funkcioban hozza lehet adni a Home Assistanthoz?

if you use the one L as 220 and the other as 24 is that ok?

Excellent video! Is it running ok with Google assistant / IFTTT ?

Can this work with rf Roller shutter?

Thank you for the video! I'm trying to use the Shelly 2.5 to control a 3-wire ball valve using 24VDC. The 3-wire Ball Valve requires that the (-) be fixed and the (+) is used on the other two wires to open and close the valve. It looks like the Shelly is setup to use the opposite strategy with the N being (+) and the (-) being used to switch the circuit. Here's a video that claims to connect the two, but the diagram has the (+) connected the ball valve (-) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1TDPb9TAnVo.html. Any ideas? Thanks!
