Yolink API

This is a response I received from Yolink regarding them exposing their API:

Thank you for contacting us and for using YoLink products. I am sorry about the slow reply.

You can go to YoLink App->My Profile->Settings->Account->Advanced Settings->User Access Credentials to get the API key.

Please follow the documentation on http://doc.yosmart.com/docs/protocol/openAPIV2/

The API server should be https://api.yosmart.com

So, you should POST http://api.yosmart.com/open/yolink/token to get the access_token through your UAC, just as described in the documentation.

Please refer to the documentation:

1: Get device data through API:

2: Get data reported by device through MQTT:

By the way, the plug-in for home assistant would be released at the end of March.

Let me know if you have any questions or need anything else!

All the best,

FYI - cloud access only. They claim that local access will require new hardware.

Which is why I won't buy any of their devices. Too bad, because they are nice.

But I'm not getting locked into anyone's cloud/cloud API for core home automation functions.

I think they were so close to being an awesome offering, but excluding the local control route shut out a lot of customers. Maybe they'll change in the future.

I concur. I have no issue with my bed being automated via the SleepIQ cloud, because I can live just fine without that automation. But a leak, motion, or contact sensor should not be dependent on someone's cloud, or my internet connectivity.

Yup. I would have bought a couple thousand bucks of devices for my vacation house if they had local control (API or even local MQTT would be fine). But they don't, so...

Does anyone know how they get incredible range? The frequency seems very close to the USA z-wave frequency(908.42mHz) and Yolink is like 923.
Plus their devices are very affordable

Lora. It is similar to Z-Wave LR in how it works. I can get a mile plus out of my homemade Lora devices, it's a nifty protocol / encapsulation / radio use method.

Just keep in mind if you buy into yolink's ecosystem, you're locked in to using their hub and their cloud. There is no local access or local control at this time, and while they say they may or may not do something around that later I always recommend not buying products for what they "might" do in the future because that often doesn't happen.

So if local access to the devices is important to you, stay away from yolink. If not, then they are cool devices.

I have a sense that when Z-wave LR devices finally show up, they will be at least 2x the price of these yolink devices. In that case it's cheaper to buy another HE hub and use Z-wave+ devices for the problem area

It wouldn't surprise me if zwave lr cost more (even though there is no technical reason for them to). Who knows though? With all the chip shortages it may be forever before we actually get any real devices.

That's why I still say that if yolink had any sense whatsoever they would add local mqtt support to their existing hub. I highly doubt that would require new hardware as mqtt is extremely lightweight, and it would pull in many many enthusiasts that want local monitoring/control.
