Next time I’m on my desktop I’ll grab some screenshots
Thanks
I think I got it working just before your post, and was trying to get the color mode in, but yup broke it 
I have the fan modes Normal/Sleep/ECO changing so far, now for the light color mode
Here are the settings to get the colour mode and Fan modes working
I will try and see what else I can get maybe tomorrow
A quick update for anyone that might be interest In the ECO3 Products ,
I have posted it in the hardware section. It felt like the correct place as I was stuck identifying the little cheeky extra micro on the board.
( First time dealing with Tuya crap )
Thanks for sharing! Let me know how you go. I think I need to update to get the option to type in values, this always scares me with braking changes now, and the wife isn’t happy when I tell her, oh sorry that doesn’t work now because I updated…
Any suggestion on power supplies for my first esphome device:
the input at the top has three connections. 7-28v, GND and 5v. Using this for controlling solenoids for irrigation (not yet purchased)
How much current does it draw with all the relays on?
Jaycar sell plenty of approved 12V or 5V plug packs, up to 3A.
I made the same thing. As I used 24V AC solenoids I used a 24VAC plug pack from Jaycar and switched that through the relays as well as sending some via a home made rectifier (4 diodes and a capacitor) and then into a buck converter to drop it to 5 V to run the ESP board and the relay board.
Edit: if that has its own voltage regulator then you could pipe the 24V straight in
Thank you both.
I will look into max current and if it has a voltage regulator.
Sounds like I want to match the solenoid voltage to the voltage of an AC power supply?
Edit,
Reading the aliexpress descriptions such as this one and it actually specifies a dc power supply.
Yes the board needs DC which is what the rectifier does in my case (changes AC to DC). There are DC solenoids so you need to work out which ones of those you are getting in order to work how best to proceed.
Morning everyone!
So, not sure if this is the right topic for this, but HA just had their second year of the voice announcement. Among other things was the ability to do local speech to text and text to speech. In their blog post about it, they have a section for ESPHome mics and speakers, and were talking about using something like this as a cheap way to have a mic and speaker that works with HA
My question for this topic (and sorry if it’s a very basic question, I don’t know much about hardware and how a lot of things work) is whether buying stuff like this from overseas is ok for use in Aus - I don’t see any official certification for us here, but I’m pretty sure it’s just a 5v cable in. Is that ok to buy from overseas and use here, or are there risks involved and it shouldn’t be done?
Thanks in advanced!
I think we must have discussed this before (maybe on whirlpool) as the rectifier rings a bell and it scared me off at the time.
I’d like to keep things simple, so if that means finding a dc power supply and tracking down 24v DC solenoids that sounds like a plan. (EDIT: reading that AC solenoids can work with DC power? Does the power supply voltage need to match the solenoid voltage for this type of relay board?)
I think i’ll run a main line around the perimeter of the backyard, then junctions with solenoids in line off that to my zones. Plan for now is 4 lawn sprinklers in 2 or 3 zones and one raised garden bed zone with small sprayers or drippers. i’ve made a scale architectural drawing below
Just be aware that ‘standard’ solenoids are 24Vac so really it’s best to stick with those. If one fails you can easily by a replacement at Bunnings or irrigation shop. Using a rectified etc to use that same 24Vac and convert to 5Vdc is not hard. It’s what I did.
I am still hugely confused as to what i actually need to do so i think i’ll find a thread on this topic to avoid clogging this one with my questions. Thanks all.
This is old as I haven’t shared my latest setup yet but it should give you some idea of what you can do. Somewhere I have a post showing my enclosure etc but again, it’s old. I now run a PoE ESP32 as the controller and the relay board is powered from that so the 24Vac is only switched by the relays and sent to the solenoids and pump contactor (I have a bore).
There’s a reason swimming pool lights, and irrigation systems etc use AC power - it is less susceptible to corrosion than DC. ChatGPT (via Bing’s new AI search) sums it up pretty well:

Id also say you probably don’t want to have the solenoids all scattered around like that as you have to run wires to each of them. Typically you have all the solenoids in a box in the garden and you run a multi core cable to it. In your case you could use five core as you need one wire for each solenoid and then a common ground for all. Here is an example of a manifold https://sunshoweronline.com.au/complete-irrigation-manifold-bundles-inc-hunter-pgv-valves/https://sunshoweronline.com.au/complete-irrigation-manifold-bundles-inc-hunter-pgv-valves/
Looking at this link the DC solenoid may not be fail safe. If you lose power it might stay open but this would depend on how your specific one works How to Choose a Solenoid Valve - Irrigation Express

I assumed multicore wire would work in either case, i’d just be tapping into it at the desired location?
Only reason I was really thinking of doing it that way was a single cable for power would probably be cheaper than 5+ runs of irrigation from the same point of origin. Am i overthinking it?
