this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
Does this help:

I agree with you that the serial messages are not perfectly documented, but realise that this site has been made (as far as I know) by a bunch of people that share their 'love' for home automation.....

Well, for small potted plants, you might have to re-pot the plant. However, the nice benefit that would arise is: no visible sensors, which carries with it very high WAF.
@zeblong, you can generate these from the board files, however i'm leaving this one for @Ivan-Z to discuss with you as this is his device and he knows all details regarding this.
@mjdula
The 85 reading is actually an error message used by the ds18b20 to indicate it has not had time to complete the processing of the reading. Most commonly this is only seen when the node first boots up and can be ignored or fixed by adding a small delay. You will find a lot of information on this if you do a google search. I have never experienced it myself but from other posts on the net it seems power supply problems and long cable runs to the sensor can also cause the error. Some have also had success by using a different resistor value. Note you only need one resistor fitted near your nodemcu not a resistor at each ds18b20.
If the 85 reading is well outside your expected reading you could just filter out any readings over 84 as well.
I think the comment in the routine
void measureBattery() {
// R1 = 1MOhm, R2 = 220 kOhm
Should be
void measureBattery() {
// R3 = 1MOhm, R2 = 220 kOhm
(R3)
Is it possible to add (comment out) some lines how to calculate the battery percentage and send this via gw.sendBatteryLevel (batteryPcnt)
Great sketch!
The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle.
In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V.
Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work.
Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).
I apologize for the questions and how simple they may be, as Im new to this community but very intrigued with the creativity and endless possibilities.
