Robot lawn mower!

I need a little help! “robot lawn mower”


I want a mail when the robot mower is not returned to the charging station!

I have a power meter on the outlet. :-)


  • -power use out of the charging station less than 3 watts.

Conditions:

  • -between the hours of 8:00 to 22:00 (8 am to 10 pm)
  • -action/mail when it has been out more than 2 hours. (consumption under 3 watts for 2 hours and more)

Hope my Zipato family will help? :-)

Mads,


Enclosed please find a rule created according to your requirements. Please note that for clarity, the example assumes a Scheduler running Every Minute (hence the test for Timer > 120 minutes).


Please also note that this rule tests for 120 minutes absence within your specified time window, as stated initially. If, on the other hand, you want to also check that the robomower actually returned home for the night, and get notified at 8:00 if it didn't, please use the second rule instead.

Mads,

This should be pretty simple to do, but we need to complicate things a little bit due to Zipato's lack of possibility to measure elapsed time between two events.

The very first thing you need to confirm, is that your power meter does in fact send events about the relevant changes in power consumption.

The best way to do that, would be not sit and watch the live event viewer, but rather to send yourself a message every time <consumption> changes on that meter, and if you have PRO, also the actual consumption value, then see what happens.

If the change in consumption between charging and not charging is so small that no events are being sent, you would want to find out if the device can be set to send messages often enough for your needs.

Mads,

You need to reset the Timer after the message has been sent, otherwise you'll get a message every minute. Add SET VARIABLE <timer> TO 0 just before sending the message.

-Or you can set the timer to 110 minute and get a new reminder every 10 minutes if it is still not charging...

Hi Robert,


Yes, the power meter does send changes in power consumption! (Fibaro Wall Plug)

From 2 watts (not charging) til 60 Watts (Charging)


Mail when consumption under 3 watts for 2 hours and more......(no charging)


Hope my question is understood :-) hihi.....

could just install a contact sensor on the mover and charging base. I think this would be far easier and cheaper

Adrian,

Great thought! You're absolutely right on: Sticking the magnet part of a door-sensor on the robomower at a spot close enough to match the sensor stuck at the charger station when the robot is "home", is definitely a simpler and (perhaps also) cheaper solution.

I would suggest using Sensative Strips for this: The magnet is small and lean, and the sensor doesn't need battery changes for many years. -And it's weatherproof for outdoor use...

agreed, and weatherproof. easy.


Sometimes we can over think the solution, and the simplest solution is best.
