Thanks Yveaux, This led to a whole new range over errors : call of overloaded 'set(float)' is ambiguous I resolved the issue by changing the send command from : send(Phase1_Current.set(m_Phase1_Current)); to send(Phase2_Current.set((float)m_Phase2_Current,1)); Which is working fine now.

Did you ever get this feature working on the RS485 transport @Redguy ? I'm also building a rs485 mysensors network and would love to know how you went.

Thanks guys ! Since i am using Domoticz, i'll stick to unique ID's overall.. That would mean that you cannot use the "auto" setting for ID's if you are using multiple mysensors gateways with Domoticz at all..

Thanx guys ! I ordered a ADXL345 digital three-axis acceleration of gravity tilt module on ali to see what this will do with such small measurements. stumbled upon this via one of Wallyllama's links : https://tc1seismometer.wordpress.com/2012/06/18/tc1-vertical-seismometer-plans/ Seems easy enough to have some fun with as well.

Tried ir, but no change.. Serial0 was still used while serial1was defined

So first i pull the mysensors code from github to my raspberry pi. For running a mysensors gateway node on my raspberry pi using RS485 for transport i would then set it up with :+1: ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSBMySGW1 --my-transport=rs485 --my-rs485-serial-port=/dev/ttySC0 --my-rs485-baudrate=19200 --my-rs485-de-pin=23 Then make and make install that gateway and voila.. I can do the same for an RF based gateway running on the raspberry pi itself using a directly connected NRF module, which would recreate the mysensors files and install those. Which means i have either the RS485 or the RF gateway. Not both at the same time. My point is, how to set this up properly so i can compile 2 mysensors gateway instances on the same raspberry pi and run them at the same time. 1 for RF and one using RS485 ???

@Redguy from http://m.electronicdesign.com/what-s-difference-between/what-s-difference-between-rs-232-and-rs-485-serial-interfaces: "A logic 1 is a level greater than –200 mV, and a logic 0 is a level greater than +200 mV. Typical line voltage levels from the line drivers are a minimum of ±1.5 V to a maximum of about ±6 V. " So you should be able to mix them as much as you like.

I think people are running MySensors on ATmega32U4 without any problems... I.e. @fleinze https://github.com/mysensors/MySensors/pull/378

@Redguy Did you succeed talking modbus and sending to mysensors network ? I have a small mysensors over rs485 network and would like to add this device : https://fr.aliexpress.com/item/4000478781091.html?spm=a2g0o.cart.0.0.1d513c00qfPO3K&mp=1 it would be convinient to use the same cables, ideally the gateway could make the translation directly.

You'll have to use separate gateways.
