Yes I can. I tried to simplify the flows a bit. If it starts or stops raining, the countdown timer will reset. After 36 hours (129.600 sec) the timer will end. So it will end when it was dry the last 36 hours or it was raining for the last 36 hours (which is very rare, so I think it can be defined this way).
If the timer is empty at 20:00 and it was warmer than 15 degrees that day, then start watering the garden. Please find the examples below:
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
Thatâs 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 investmentâŚ
I tried to make it work using Homeys 433MHz receiver but I couldnât work out the codes coming back as it looked completely random in Homey. Probably using an unsupported transmission method. Also the range meant Homey couldnât 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 doesnât seem easy to convert that work to Homeyâs implementation of the radio.
Also, now that I have put the sensor in the garden, my Homey doesnât even detect it on the radio capture. So I think the hub is the best way to go as it is so cheap.
Iâve 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 âdevice timed outâ error). I then have to remove and readd it to make it work for a while again.
Hi Hannes, seems like zigbee mesh and or zigbee/wifi related.
Do you have enough router devices? Whatâs the distance to the nearest one? Athom zigbee advice
If you run firmware v5 or higher: did you perform a zigbee reset after update to v5?
(Be warned, all zigbee devices have to be re-paired, and flows need to be fixed)
