This is a post dedicated mainly for Singaporean’s using Home Assistant. Just wanted to share some findings as it might affect many of y’all when doing renovation/buying a new home.
PRISM Plus, is a Singapore Local Brand that primarily rebrands OEM Products as their own. They recently branched out to stepping into Smart Homes and their first products were AC Units. When I first looked at the AC, I felt that I had saw this AC before somewhere and turns out, it was a GREE OEM AC, just rebranded.
I chanced upon the opportunity to try out a PRISM AC and managed to get it working directly using the Gree Climate integration.
Initally, had checked with the company multiples times on whether their devices support Tuya or any Open APIs that we can work with. They were reluctant to give me a proper answer and was dodging all the questions asked.
Here is an image of what the Prism AC exposes, pretty much everything from a normal GREE AC.
On Home Assistant, Add Integration and add the Gree Climate integration, the devices will automagically pop up.
As PRISM seems to be directly acquiring OEMs from GREE and PRISMs application simply being a reskinned version of the GREE Application, we can expect to see their future ACs being GREE as well and compatibility with Home Assistant should be compatible for future products.
It also seems that the Compressor Unit has nothing to do with the AC’s Compatability at all as well since the WiFi Module is located inside the Fan Coil Unit. Similar to Daikin (iSmile) ACs and MitsuCon Mitsubishi ACs.
Great stuff - am in Singapore and been checking out the Prism+ stuff with great interest. Good to know there is a working integration. Do you happen to know which OEM they sourced their new smart fan from?
Thanks, this was very helpful! I am running three Prism+ Acs connected to HA.
Anyone had any success connecting the Prism+ Oasis Fans? I am unable to connect those …
As of October 2024, this hack doesn’t work for me anymore, they moved away from the Prism+ app and are now using the Prism+ smart connect app. I wonder if we can connect manually?
Also based on Gree. After adding the gree integration, the entities popped up automatically.
Based on this I suspec that they’ll work without internet access but I will only test that later. You will still need the prism+ app (or possibly the gree app) to connect to your wifi initially (use bluetooth mode when pairing for the neo; wifi pairing doesn’t work) but after that I’m quite certain it’s local.
With the neo AC. Updates from remote/app to Home Assistant are typically slow but can range from a couple of seconds (same delay as app sees when using remote) all the way up to several minutes.
With swing/oscillate
the remote can pause either in any position
the app can set preset angles, full swing/oscillate, and off
while Home Assistant can set full swing/oscillate or MIDDLE angle only (which is their version of OFF).
Quiet fan speed equates to Low, and you cannot set Quiet from Home Assistant.
The above HACs integration solves all the previous issues (with “Default” swing mode being the equivalent to a pause); except for the delay when showing updated states in Home Assistant.
It achieves full feature parity and then adds more.
Deleting the old Home Assistant entities (as they’re tied to the original integration), then re-adding the integration (as this one overwrites the core), works. I am still able to use the app as well.
