@Yveaux Thanks, that was exactly the insight I was looking, for my door sensor with 2aa battery, your way worked great. For a scene controller with a CR2032 a had to not send also decreases greater then 10%, but hey, 10 steps is more enough.

For having consistent measurements with a CR2032 you should measure voltage as first action after waking up from sleep.
I keep the value in a variable and process it after "action" message of the node.

If possible, run at 1Mhz on internal oscillator so the power consumption of the atmega stays very low (around 1mA instead of 3 at 8MHz/3V).

Hi, I do read the battery first thing after wake up, my problem was when a had various click too close together. It`s good now that I only send battery values that a 10% higher or lower than my last stored value. I will take a look on the 1Mhz bootloader. Thanks

@Yveaux I know about that fluctuation, but for my use in a scene controller I would be happy just to know the battery is low. I have it running with a multi-button, were I have click, duble-click and click and hold, I only check battery at one click, because of its fluctuation, but if you use it more than 4 times e a short period that fluctuation is noted, and that is why a added to the 10% increase a 10% decrease gap on battery sent information. Thanks

@Yveaux Hi, thanks for your work. Maybe I´m going over something that was covered before, but I need some help, I´m using this code in a door sensor with 2 aa battery, and reporting if battery changes, when the door opens or closes. My problem is that I always get diferent readings from close to open, so I´m always reporting battery level and using more power than needed. Thanks

@Boots33 Thanks, that was exactly what I needed. Synchronizing was a great bonus.

@niccodemi

Hi, I know that this is quite old topic, but only now I´m updating my home from version 1.5.4 to 2.*, most because reability issues. One thing I notice with you skecth is that if by any chance the gateway is not present the nodes can´t be used anymore after a power loss, I mean, one can not use the fisical buttons to switch the relays, because they will not respond. My question is if there is a way to keep the node up with out the gateway, in case it dies?

Thanks

@matt-shepherd Never got the time to do it. Sorry

@bkl Hi,

Use this biding from it`s beginning, many thanks again. Just want to know if there is any function like the "ack" as there is on OH2 binding, where gateway re-sends the msg 5 times if it does not hear from the sensor after a command. It´s a killer function to make it more reliable, but I´m not ready for OH2 yet.

Thanks

@xefil

Thanks, I got it working the way it is there, for the Domoticz, on my Openhab. Using 3 separated slides, but now I´m trying to use the color wheel to set the colors with Openhab as the controller.

@mortommy

Thanks, It seems great, but I will only control it from OH side. Unfortunately no Ikea on my country. Having that control would be great. If I can´t find anything simpler I will try to adapt that.
