Silly question,

I have a 3v pro mini running on 2x1.5v batteries......this works perfectly well.. however i have tried to add in a "DC-DC Step Up Boost Module 3v3" if i add this to the circuit the pro-mini does seem to turn on but the D13 Led keeps flashing on and off and it does not seem to initialise the radio with a lot of fail messages in the serial monitor.

I do come from a programming background and lets just say im not the best at the electronics side, but im getting there...At the moment i just added the boost module on its own,,,,do i need capacitors?

Many Thanks in advance
Lee

that i can do

perfect,,

thank you..

in HASS there is a field within each sensor for battery life, how do i put data in there?? I do not want to make a new sensor purely for battery level..

{
"V_STATUS": "off",
"assumed_state": true,
"battery_level": 0, <------ want to put data here....
"child_id": 1,
"device": "/dev/ttyUSB0",
"friendly_name": "Test 1 1",
"node_id": 1
}

thanks in advance.

I have a relay actuator and was thinking it tidying it up be putting on a FR4 pcb with a hilink HLK-PM01 220v to 5v.

Am I ok to put 220v on an FR4 proto board??

@HarryDutch OMG your a genius, I do have LEDs on....I thought that only applied to gateways for some reason...

Don't know why I didn't think of that

Its on a nano........ Basically I have 2 relays and 2 buttons on the following pins.

D3 - Realy1
D4 Button1
D5 Relay2
D6 Button2

on startup D5-6 seem to go high/low a couple of times. and it randomly thinks I am pressing the button on D6. it I move to use D7/8 it all works perfectly....It could be a dodgy board but I don't have an extra spare at the moment.

Is there any reason that i cannot seem to use pins D5 and D6. when i try and use these pins i seem to get very random results, if i use D7 and D8 it all works fine. I noticed that there is a white circle around the D5 and D6 pinds on the connecting diagram, does this have any meaning ??

Thanks in advance.

I am using mysensors/home assistant on windows.....its working fine....here is my conf...

mysensors:
gateways:
- port: 'COM4'
baud_rate: 115200
debug: true
version: '1.5'
optimistic: 'true'

Hope this helps...
Lee

interesting.....thanks for the link

Sorry, I should clarify....

Can I get the mysensors gateway running on a Yun?? i.e. will it use the inbuild network card to get to internet??

I didn't think about running the MQTT server directly on the Yun at the same time....I might give that a go...

Thanks
Lee
