Relay for several low AC voltage like 24v

Hardware
21

Yes, the one I send can be powered from 240AC and it can switch whatever voltage you put in to the other side as long as it isn’t more than 240vAC 10A.

Thanks @SvenBosma , I am going to order one right away and test it! One more cuestion, is it easy to flash? I mean just plug and flash or do I need to solider extra cables? TIA

Well, if you have a ch340 module, you just have to connect it to the board with RX to TX an TX to RX, plug it into your PC and flash it with your software (I’d choose tasmota).

Thanks again. Yes, I do. So I will try it and lets see what happen. I am going to try first with the 220v but later I will also try with the lower voltage (They are cheaper). As long as the power for the board goes separately from the relay I think that it will do it. I really apreciate your help. Thanks

Yes, the power goes seperate from the relay. You can even power the board from a 5V phonecharger.

Can you keep me updated on how it goes?

one of these.

bung a custom firmware on it if you like.

if you chuck a bridge rectifier and a cap in line you can power it from the 24V AC too :slight_smile: or just use mains if you have it closeby.

super reliable IMHO so far so good :slight_smile:

Of course, I will keep you updated, just be pattient because the items take about a month to arrive usually where I live.

Thanks Jon, that is what I asked some post above, I’ve already ordered one. Let’s see how it goes. Having single channel option is good for me too. I will try all of them, and I bet that the sonoff will be easier to flash for me because I am used to work with them.

By the way, flashing the board I send you should work exactly the same as flashing a sonoff board. So no worries there :).

Thanks! that’s a thing I am very concern because of board like this one https://es.aliexpress.com/item/32821721218.html which result a really pain for me so I left them behind. Sometimes it is better to pay a bit more and save some time.

these boards are natively supported on Wespota. (a Tasmota fork)
the ESP01’s are a bit of a pain to flash compared with the button on a sonoff but nothing you cant find on the tube.

Thanks for the info, I always try to use my own firmware, I am sure that it is on internet and I’ve tried it many times following many tutorials with no success by now. I haven’t surrender, just trying to save some time.
