Cheap eBay WiFi heating controller,

So I’ve emailed the sell of these, to see what app it uses.

But for the price i might just take a chance on it, as sniffing my danfoo 433mhz central heating contoller doesn’t seem to be working.

Very interested in this, let us know how you get on :slight_smile:

I will, tho I’m still trying to find an answer on the difference between. Underfloor control thermostats and normal central heating ones.

I think that central heating ones just out put 240 on the signal wire, with little/no current available, and underfloor will output 240 with 1-5 amps available

There seem to be many very similar (if not identical) products around, on AliExpress too.

Hopefully I can my question answered by a heating professional tomorrow (about the difference berween an under floor thermostat and an normal thermostat)
Then I have wife approval to build this (only cuaee it mean she can turn the heating on in bed !)

Ordered, might be here for the weekend.
Now time to setup a new vlan and break out Wireshark to work out what it’s doing.

Looking forward to your results :slight_smile:

Looks like it’s the same device discussed here
I’m using a version of these for a boiler, integrates well.

Awesome find !

Well, I’ve just ordered one too, so I’ll keep my fingers crossed that it works with that component linked or that @cooljimy84 can work something out.

To be fair, at under 30 notes I can’t complain much if I can’t integrate it in to HA, but I’ll be keeping my fingers crossed that it will :slight_smile:

Not sure I can get to it without unsoldering it

a little googling show it as a WT1SBSL Boardlink, found a guy that took apart a smart plug and found one of these in it.

Thanks all she write for this one, i’l see if the above link to another post gets this working as expected.

This is far more exciting than it should be really, but given that my original plan was to buy a nest for like £200, and this looks like it’s going to be doing the job for £28, I’m well chuffed.

Hoping mine arrives before my days off next week, by which time you’ll have it all sorted by the looks and I can just copy what you’ve done :smile:

Thanks again for starting this thread and keeping us up to date.

Following this closely! I was literally about to buy a nest this weekends just to use as a simple smart on/off switch!

Edit - Hmmmm my thermostat at the moment is RF as there are no actual wires in my walls for a thermostat… I don’t think this will work…?

I imagine it is controllable by Wifi, but connects to the boiler via wires? rather than connects to the boiler via wifi?

I have no doubts it will work. Lots of brands are selling this thermostat.

Don’t expect much as a standalone, the temperature ain’t reliable (.5 to 1° random difference with others sensors) and I don’t find the interface easy to manage.
But as a climate component, using other temperature inputs and the automation capabilities of HA, those are no problems anymore.

You can connect it directly to the boiler as there should also be power supply there. Then HA will control it.

I had thought that, but when I just discussed it with the wife (I thought it would be a good idea to ask her if she wanted to save £170 over buying the nest) she said she would still want it in the living room in case she wants to over-ride Home Assistant via the thermostat in the living room if her phone is out of battery… :frowning:

I suppose I could just put a tablet on the wall in the living room showing HASS with a fancy nest lovelace card…?
I’d just need to somehow improve the Wifi in the utility room to ensure the wifi thermostat has a rock solid connection…

Wifi is terrible in my house, Sky Router + 100yr old stone house I looked at getting a mesh network but it would still struggle because of the 1mtr thick exterior walls before the extension…

Not sure if i will have time this weekend, as i need a back box for the unit (as it doesn’t come with one) and my new build flat seems to have a whole in the wall where the fitter just cut a hole and screwed it to the wall…

So couldn’t wait and just stripped a plug and wired it in on the floor to play.

Getting it in to WiFi config made was strange, and I just overwrote my config on the thermostat by adding it to HASS
