Home Assistant & Heat Pump (Smart Life application)

[campsbayrich]

I need to replace a heat pump and I'm trying to find something that will link into my home assistant.

Installer has recommended 4.5kW Super ITS which is wi-fi enabled "for easy control via Smart Life application". Does anyone know whether that can work?

I've googled it and I think the smart life app might be the Tuya app (which I already have integrated for pool pumps), in which case fantastic, but I'm not certain whether the ITS site is referring to the same Smart Life application.

Thanks!

This thread is more around getting the ITS to work properly in Tuya Local. But the initial poster makes specific mention of " The devices are managed via Wi-Fi with the SmartLife app. I have also added both devices to the Tuya IOT platform"

So it looks like you're good to go with the Tuya SmartLife app

Thanks very much for the link @hilt_ctn

Hi, vouch, my ITS Super running smooth in HA with TL

If you are considering using a ITS heat pump, it works great with HomeAssistant.

To assist, I have setup a installation guide for installing the ITS heatpump + HomeAssistant.
Hope it can be of use for someone.


Good morning, I have created an installation guide for HomeAssistant for the ITS Heat pumps.

Please feel free to distribute this.

I have a 2 year old ITS heatpump that came without wifi. Is it possible to somehow fit this newer wifi enabled controller to an older ITS heatpump?

Hi Leon, I honestly have no idea if that would be possible. I would suggest you reach out to them on their support line
They have a whatsapp option on any page on their website - https://itssolar.co.za/products/heat-pumps/

I have recently installed an ITS 4.5kw heat pump with wifi, using the smart life app.

1. Is there a way that I can see temprature changes over an extended period and not just the current inlet and outlet temprature

2. Is there a way that I can track the power consumption of the heatpump over an extended period.

Regards

This may not directly help you, but I use Home assistant to record the temperatures from the available ITS readings.
I have installed a Sonoff POW3 in front of the heat pump to accurately measure the power usage.
I have attached some history graphs from Home assistant to show some of the values captured.

Thanks, will try that as it is what I am looking for..

I have an ITS heat pump fully integrated into HA, but discovered I could do much more via the "local tuya" integration. It exposed more sensors.
No expert, so literally sat with a YouTube tutorial (quite a few out there). Was a pain, but probably took about an hour for a n00b like me.

The heat pump is linked to a few automations, like triggering only when the geyser temp is below a certain level AND their is sufficient solar generation and/or battery, at specific times of the day etc).

This is my current dashboard (old iPad mounted to a wall), which has some of the heat pump data.

There are some charting cards in HA that allows me to monitor temperatures over time, for both the geyser and the heat pump. Will need to find them when I'm back home, but YouTube / google, is your friend. So is ChatGPT!

I dont think they have power monitoring, well my one I installed last week does not have power monitoring. So I installed a Sonoff power monitor flashed with ESPHome to monitor power. This is what I have done with my dashboard:

First block is the Heat Pump control provided by Tuya, 2nd line ESPHome, 3rd Tuya, 4th and 5th ESPHome.

So it seems ITS have changed something, and the pool heat pumps no longer work with Tuya Smart. For mine which arrived last week I had to use an app called iLetComfort. Bit of a pain as that doesn't integrate with Home Assistant, which I was banking on.

Tried adding it just as "other" device and see if it comes up? More than likely you just need to figure out which device it will pair as.

@MongooseMan - I'm about to purchase an ITS Heat Pump, and it seems they've moved over to iLetComfort.

I have found this article where they have managed to integrate it with HA: https://community.home-assistant.io/t/midea-clivet-italtherm-app-iletcomfort-integration/798699/5

Would you be so kind as to follow the steps in there and see if you can get your heat pump working - and let me know if you are able to switch the heat pump on and off via HA.

I don't want to spend the money on something that can't be integrated with HA, as then I won't be able to automate when it's on and off.

Ok, I managed to get it into the Smartlife app, but when adding it to Home Assistant through the Midea AC Lan integration, the sensor values are nonsense.

Will do some digging and see if I can resolve

Ok, thank you - REALLY hope we can figure it out.

I believe it does have MODBUS and a RS485 connector, so if push comes to shove, we'll just likely need to build a small integration to control it directly

I'm also looking at integrating my ITS Heat pump. I've tried tuya-local, which worked initially, but now cannot connect to the heat pump since I blocked it at the firewall. I did block both DNS and wider internet connectivity, following the notes on tuya-local about blocking Internet access.

I ended up removing the block, and still had problems, until I re-paired the device with the network. But that leaves me with a device connecting out to the Internet, which I don't like very much.

Taking a look at the insides of the display unit, I see that it is based on a WBR1 Tuya module, which has been successfully reflashed via the LibreTiny project. That should be one approach to gain reliable local control of the device. Alternatively, the connector to the heat pump has A and B connectors marked, suggesting RS485 (and probably modbus). So, hooking up an ESP32 with a RS485 transceiver in read-only mode should allow for snooping on the bus and validating the above assumptions. Anyone else done something like this?

 

[RoganDawes]

Update: I took another look, and unfortunately, the WBR1 modules are NOT easily reflashed. This is because the pin required to enter the bootloader is only available *underneath* the module. i.e. it needs to be desoldered in order to access PA0. There is an option that relies on extracting the secrets from the module via the logging UART (https://github.com/tuya-cloudcutter/tuya-cloudcutter/blob/main/running-with-known-secrets.md) which may still be possible, but I have not yet investigated this.

Another possibility is to disconnect the ITS control panel entirely. It is connected to the compressor via RS485, and talks modbus. With some reverse engineering to determine the registers being polled, and interpret those responses accordingly, it should be possible to directly control the compressor, using something like a TCAN-485, or any other RS485 transceiver attached to an ESP32.
