Hello, no there is no minimum frequency but for a serial gateway I would keep it at 16MHz to avoid any missed messages. It also allows a high baud rate on the serial connection.
For battery powered nodes I use them mostly at 1MHz, there's not much interest going lower as you get no more gain in allowed voltage and not any significant gain in power consumption while the processing time increases.
@johnrob said in Why I quit using MySensors for actuators:
Hi, I know I'm a little late to this thread. I'm just starting with MySensors and am learning by reading the posts.
Currently I am waiting for hardware for my 1st gateway so I am not encumbered by details.
I notice in all the reported cases the "problem" node is AC powered, while many of the "good" sensor nodes are battery powered. Could this be significant? It would be interesting if someone with a "problem" actuator node could put a battery operated sensor node in the same area.
the problem is an actuator node has to listen to the radio constantly and can't sleep, so it can't last long on batteries...
Serial input will come from a windows based PC. Probably the same as the one that acts as the datalogger.
The actuator could be any actuator-node.
To give you some more info:
I have some lights in my shed (mancave actually.... ) that should turn on when pressing a button, somewhere nearby, i.e. near the door. This button is connected to a node that sends the command to the actuator node. setdestination will play a role in this node.
There's also an automation scheme to turn on (and more important: off) the lights. As the shed is quite far away it is very handy to turn off the lights when I have returned to my home and forgotten to turn of the lights (for whatever reason). For this purpose I will use this specific node. Once I manage to controll the lights in the shed, I will be able to controll some more things around.
I've added LED strips under my stair threads for night use. I've learned the "Daylight" (most blue / harsh of the white) is the most efficient. It seems to make the "warm" whites some of the brightness is "consumed".
My lights are running at ~ 1% on time (153 hz) and work great at night. There are 6 meters of light consuming 0.5 watts (including the AC adapter). The cost of the LED strips is trivial. Look on ebay, you can probable get 2 or 3 different kinds for < $10 total and see which you like best.
That's right @gohan , if you place the "door closed"reed near the floor then only first interrupt should matter, first interrupt should tell you the door is closed. Same for a second reed placed high - the "door open" reed, that would tell you the door is open when interrupted the first time. @McQueen, could be close to you needs ...
It certainly looks to me like some issue with power supply.
Have you added a capacitor close to the power pins of the radio?
It's also a good idea to power the radio directly from the power supply instead of through the arduino supply which is very limited.
