I am looking for an 18A smart plug (Europe version).
That works with Homey Cloud.
So I can “flow” the hot water production.
If solar production >4000W => turn on the water heater.
I have bought the Tapo P110 since it’s wifi based and the app should connect with Homey…
But apparently that fails!
So what other plugs exists that can take 18A and Homey Cloud (not the Pro version)
I am also open to a Smart Switch.
(allthough it’s a bit less user friendly).
But I can’t seem to find any that will work with Homey Cloud?
I am trying to help out some customers to improve their autoconsumption of the solar production.
And that’s why I wanted a solution with Homey Cloud (and Tapo, but that isn’t working)
Smart switches will probably have the same (16A) limitation. What kind of inverter is being used? Or perhaps there’s a smart meter that can be read (you won’t know the solar production per se, only how much is flowing back to the grid, if that’s how the system is set up).
It’s a Growatt inverter…
I know it’s not going to be 100% correct.
But after some weeks of data I will be able to set the correct threshold value.
So that the customer has warm water while limiting the power import.
Most switches I found where also not suitable for WiFi/app control.
Measuring would be nice.
But most importantly is switching.
The ZigBee devices seem to need a Homey Bridge?
I was hoping to build a solution which only need the Homey app.
In theory I solved it with Homey Cloud app.
Growatt inverter which is connected through the app.
And then the Tapo WiFi plug.
But although they are listed, the connection/setup in Homey doesn’t work…
Try one of these. 40A. I used one to isolate my 3kW solar inverter. Works really good. The link is to an Australian site, but being Aeotec I’m sure they must have a european version.
There might be an issue with the Tapo app for Homey not letting you add the P110. They only added support for it at the end of February. I just found out about this today because of your issue. I’ve got two versions of the Tapo - P100 without power metering and the P110, and I couldn’t use the P110 until today.
after the update I was able to at the P110.
And I got the first (very basic) flows running!
Now I need some time to learn how the consumption of the boiler looks like, and then we’ll start adding some more logic into it.
