@segelmann Great to see you are having fun on your Mysensors journey. A reliable connection to your nodes is a most important piece of a Mysensors setup. This becomes very apparent when you start deploying light switches that require an immediate reaction once activated. There is nothing worse than to gather all your family around to show off your latest piece of node wizardry only to find it does not perform as expected every time. For nodes that are to be on the fringes of range I use this mod to the antenna, In testing I have found it to make a worthwhile improvement to range. For my outside network I used this method to first establish the reliable range from my gateway , then once my first repeater was established used the same method to place the next repeater within range of my first repeater. By using the antenna mod and correct repeater placement I now have reliable connections to my nodes over 100m away from the gateway with just two repeater nodes. You will find that once you get clear of buildings you will get a sizeable increase in the distance that can be covered reliably. There are a few things to remember with repeater nodes, you cannot use sleep or delay in their code as this will prevent them from working as a repeater. You should try and have the repeater node as high up as is practical and clear of surrounding walls etc that might impede their signal. Nodes that are on the fringe of range from the gateway may still connect to the gateway instead of your repeater and thus still give you unstable results. To prevent this you can include the code below . #define MY_PARENT_NODE_ID 11 // set this to your repeater node id #define MY_PARENT_NODE_IS_STATIC // this will force your node to use only the repeater this must be added at the top of your sketch before #include <MySensors.h> and will instruct the node to use the repeater at all times. Of course you must ensure that the repeater is always available.
