I don't know that silicon is sufficient, but if it isn't it might at least slow down the degradation process.

Silicon is water proof, but not vapor proof. Else, it would not cure ;)

I have put glue on top of the soldering

WARNING!!!
I opened one of my items which didn't worked since many weeks ago.
I putted it on a table and should just open the stuff when I saw some brown water coming out from the pole.
My first guess was that it was water mixed with mud but the smell was strange. It can be that the battery has leaked.

If you will build this item please seal the battery to 100%. I just put the battery in the pole but unfortunately water came in and what I think destroyed the battery!

Be careful

Just wanna update you all how the battery has been since start.
No restart since 1st September.
A few days ago we moved the plant indoor and I forgot to take out the sensor, I moved the sensor outdoor the day after

@flopp is your code should work with new version of gateway 2.1.1?
Just maked using this tutorial my gateway https://www.mysensors.org/build/raspberry and I'm getting nothing in debug...

pi@raspberrypi:~/MySensors $ sudo ./bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.1
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: !TSM:INIT:TSP FAIL
mysgw: TSM:FAIL:CNT=1
mysgw: TSM:FAIL:PDT
mysgw: TSM:FAIL:RE-INIT

In node I used your newest code for gw2.0 - is this because version mismatch or something different in my setup?
Could you update your code to work with new version?

@Huczas
I don't use 2.1, yet. I only use 1.5.1.
I don't have any knowledge of 2.x, so I cannot update the code, sorry

[Huczas]

@flopp just release that @mrwomble was posting that updated code sorry. @mrwomble can you help?

Hello All,
Wondering if any one of the successful implenters would be able to share their soil moisture graphs,both for a day and over months..

To solve the battery discharge memory issue, could a second battery be added with logic to alternate between batteries and fully discharge one at a time?

[gohan]

Charge memory is a thing of the past, lithium batteries don't have it (if I understood what you meant).

Except that, if I'm not mistaken, he's presently re-using the NiCd's that came with the original solar garden light.

[Edit: correction: I think maybe (?) he switched to Nimh. I didn't think those had a memory problem. Do they? ]

[Edit2: Maybe he'll "upgrade" to a supercap. :) A soil moisture meter would be a good application for one. ]

[gohan]

NiMh still have some charge memory but not as bad as the NiCd. I got the moisture sensors yesterday I have to test them the next days.

Hi,
I started building this great idea of solar powered soil moisture sensor. Not integrated yet in a solar light as above, but still on my desk.
I tested the sensor in salted water and I get a report of 78% moisture : based on your experience, is it normal ? Then I pushed the sensor in a very humid plant pot and read 71%. I would have expected mroe differenc ecompared to salted water.
So, would you advise to caliber ? I guess I could modify the calculation formula in the script..

Precisely, is it possible with Mysensor technology and Domoticz to push to a sensor a new setting (for instance to caliber using Domoticz each different sensor) ?

And another question.. Is it possible to ask Domoticz to show the result of moisure reading in the Weather or Measures category rather than in the Temperature menu ?
