IIC-600 or IIC-800-WIFI local API (Not Cloud)

Questions & Answers
1

I see from a few other threads that the API for the IIC-800-WIFI or IIC-600 is closed source.

My concern is that if Inkbird stop supporting this product in the years to come, that the device will become useless and stop working, with no workaround. This is an increasingly common problem with IoT devices.

Are there any plans on making a user accessible API on local network?

This way people could continue to use it without cloud integration using things like HomeAssistant.

It doesn’t even need to be super extensive in functionality, since the ‘smarts’ can be offloaded to another service.

I.e. Just the ability to:

  • Turn off / on each zone
  • Status of each zone
  • Rain sensor value (if connected)

In my case - I want API access since the IIC-800 does not have rain-skip based on local weather. This is something I’ve requested as a feature here: IIC-800-WIFI Local Weather Rain Skip, but if there was local API control, then you could ‘workaround’ the lack of this feature.

Thanks,

Matt

Hello,
Sorry, the IIC-800-WIFI and IIC-600-WIFI cannot skip scheduled irrigation based on local forecast, they require a rain sensor. The weather function is for reference. Using a rain sensor will provide more accurate detection of local rain conditions.
Currently, the R&D department does not have an open API for the device, and they need time for planning :cry:.

Hello.

It seems that a lot of time is needed … does any of your software engineer is still working on this topic or is it abandoned ?

In April 2026 still no api or method to integrate with Home Assistant …

Worth adding I also tried resetting the device and pairing it directly with the Tuya app a year ago. It seems there’s some “template” style functionality (i.e. you can see the device in a Tuya developer account, but not do anything useful with it).

Even if it worked with Tuya, it would mean you could have a Home Assistant integration based on Tuya for control.

Tryed both integrations with Tuya and SmartLive and there is no usable way to manually control or get status of channels. Very dissapointed …

Yeah sorry that’s what I was trying to say. You can see the device in Tuya but there’s nothing useful you can do with it.

I suspect their firmware has basic Tuya integration baked-in, but they haven’t ‘plumbed’ any of the actual functionality to make it work.

Considering this, there is no point in getting such a device instead of buying 2 pcs 4ch Sonoff smart relays with dry contacts and a 24V transformer for the same setup … I’ll return the device and proceed with Sonoff …
