Enabling WiFi: Samsung ASHP on Smart Things App

Guest · 2024-09-05T16:51:04Z

Hi Just had the full works Eco4 install. Including a Samsung ASHP. It has the std MIM-E03EN control panel. On the connection tab it has WiFi and it seems to be enabled but I can't detect it or use their Smart things app. Is it telling porkies or am I missing something?

@profzarkov did you install the WiFi adapter yourself, or did you get someone to install it. I also have a hive system, but would like the WiFi too use havenwise.

@richdorm hi

No I haven't installed anything

I'd like to use an app like Havenwise.

If I do get the Samsung WiFi enabled will it communicate with havenwise?

@richdorm I bought the Samsung wifi unit (Samsung MIM-H04EN EHS Advanced Wifi Receiver 2.0) and planned to install it myself. From the instructions it looked pretty straightforward. The most complex thing was locating the correct terminals in the Samsung ASHP control unit.

I have some DIY electrical experience and the right tools, power sensors etc. The only thing I needed to buy was some 4 core electrical cable. But as it happened, my installers were back on site that day to fix something else, and whilst I was out they installed it for me.

Current home setup: 12 PV panels on SolarEdge (3.84 kWp), 2 x GivEnergy 9.5kWh batteries, Samsung gen7 R290 16kW ASHP installed May 2025.

👍

@profzarkov I believe so - I'm in the process of checking with them.

Technical answer - no. In practical terms - yes.

Any (manufacturer-provided) app that controls your heat pump is not actually talking directly to the hardware. Instead, both your heat pump and the app are in communication with a middle-man - the manufacturer's servers. This means:

From the heat pump's point of view, it tells the manufacturer's servers (let's call it the cloud for now) what its settings are and what it's doing. It's also regularly checking to see if there are any instructions it needs to carry out.
From the app's point of view, it's regularly checking the same cloud to see what the heat pump's last update said it was doing and what its settings were. If you want to make a change to the heat pump and do something with the app, the app then leaves an instruction on the cloud ready for the next time the heat pump connects and checks. We're only talking seconds here, so if the instruction isn't picked up in a timely manner, the instruction's removed again and the app tells you it couldn't communicate with the heat pump.

Havenwise has been designed so it also talks with the manufacturer's cloud. In effect, all Havenwise has done is to replace the app - at least as far as the manufacturer is concerned. The clever stuff is that Havenwise's systems are making automated decisions and then effectively telling the app what instructions to send to the cloud.

If all that makes sense, you should be able to see that as soon as you get your Samsung wifi interface working it won't communicate with Havenwise but it'll be able to communicate with Samsung and Havenwise will also be able to communicate with Samsung (which is actually the net result you're after).

@majordennisbloodnok thanks - that's a very clear explanation.
