Misol Soil Moisture Sensor, lightning detector, PM2.5 meter and weatherstation. (version 0.1.3 and test 0.1.4 )

I am creating a new app to support the Misol soil moisture sensors. The app is available now in the Homey Community Store Homey Community Store and the Athom store Misol App for Homey | Homey

The app works with the Misol Gateway https://www.aliexpress.com/i/4000852618353.html and the Misol Soil Moisture sensor https://www.aliexpress.com/i/33056433752.html

To configure the gateway you will need the WS View app. In the Weather Services, select the Customized option and set the:

  • “Protocol Type” to “Same As Ecowitt”

  • “Server IP / Hostname” to the IP address of your Homey

  • “Path” remains as “/data/report”

  • “Port” set to “7777” (this can be changed if required but the Homey app will need to be configured to match)

  • “Upload Interval” set to 16

Note: As an alternative to entering Homey’s ip address you could also add it as a local url in the form http://homey-<id>.local where <id> is Homey’s cloud ID. Also notice the ‘-’ between homey and <id> as easy to miss that hidden away in there. Using this method allows for Homey’s IP to change.

Then save the settings.

The gateway should start pushing data to Homey.

Note: The communications between Homey and the gateway is over the local network so no internet connection is required. Data is pushed to Homey every 16 seconds, which is about the rate of the fastest sensor transmission rate so there is no noticeable lag.
Also the gateway can probably be located in a more convenient location than Homey so eliminate range issues of a direct connection to Homey using the radio.

Once the app has received the first packet you will be able to add the gateway device and soil moisture sensors, etc. Each gateway can handle 8 soil moisture sensors, 5 PM2.5 sensors, 1 lighting detector and one weather station, but you can also add multiple gateways.

The gateway also provides temperature, humidity and pressure data from it’s own sensors located on the short, black, cable.

Can the sensors also being used outside?

I can’t find any official IP rating so I can’t say for sure, but it looks like it should be OK. I have only just put mine outside so too soon to say if it will survive.
Luckily they are cheap, so if it does succumb to the elements then I will buy another one and add some extra protection. I was thinking of a rubber glove, using just the thumb and first finger, to put over the unit, or just put a pot over it.

Yes great idea.

I have ordered more components to add to the gateway so hopefull in a month or so when they arrive I will be able to add support for:

and the PM2.5 sensor

Hello Adrian,
I can see from web that devices are communicating via 433 MHz RF frequency. Have you tried to bypass gateway and read device values directly?

I have, but I couldn’t get a decent sample of the signal so I have no idea what the format is.
As the bridge is so cheap I didn’t consider it worth spending too much time on it.
Also, when the sensors are in my garden, they are too far away from Homey to receive any signal.

Just to confirm I have had theses sensors outside in some pretty bad weather for a few weeks now and they are fine. I’m fairly sure they are designed for outdoor use.

Mine are ordered. I hope they work.

Looks OK. I’m not what the relationship is between misol and ecowitt but I’m pretty sure they are the same products.

Hi Adrian,
I added the ecowitt.
It works really great.
Thanks a lot. I am searching so long time for a cheap soil moisture sensor.
