As addition to my previous post: this flow runs for 2 weeks now and it works fine. Nevertheless, I think it will be most reliable to use a soil moisture sensor. Since it can also rain for just 10 minutes and it will still be too dry for your garden.
Does anyone has experience with a Homey compatible humidity sensor for the garden?
you mean a soil moisture sensor ?. As far as I know there is only the mi flora, but it is for indoor use only.
Even if you can work around this and use it outdoor the bluetooth signal is mostly not strong enough to reach homey
Yes, soil moisture sensor is a better description
That’s a pity… I saw Gardena has a sensor that works with Wifi… But in that case you will also need to buy the hub. The disadvantage is the investment…
I tried to make it work using Homeys 433MHz receiver but I couldn’t work out the codes coming back as it looked completely random in Homey. Probably using an unsupported transmission method. Also the range meant Homey couldn’t even detect a signal when the sensor was outside.
The gateway seems to work well and being a WiFi connection to Homey means I can place it closer to the sensor.
I only had a quick look but it doesn’t seem easy to convert that work to Homey’s implementation of the radio.
Also, now that I have put the sensor in the garden, my Homey doesn’t even detect it on the radio capture. So I think the hub is the best way to go as it is so cheap.
I’ve been having an annoying problem with adding this as a generic device. It works flawless for a while and then it loses connection entirely (the “device timed out” error). I then have to remove and readd it to make it work for a while again.
I have approximately 20 routers and 35 end devices. There is also one router close to the woox.
It’s interesting as it seems to be triggered by something. Perhaps a restart of homey? My zigbee mesh should be optimal. Also when I move the woox closer to homey it doesn’t start working out of the blue, seems like it simply forgot the entire device.
