2 relay for interlocking system and add more security.
I never mesure my current but it's low ... not 10A !
Internal clock is not very precise and can vary with external parameters like temperature. And for this project it's better to have good precision.
It's always better to use relay driver and not directly arduino pin.

@nca78 you are right. I'm using ML01SP2 and range is not good (with PCB or IPEX antenna). I'm adding volatge regulator without success. If I put the PCB on a proto board result are far better. So it's probably interference between ESP8266 and NRF24.
I'm waiting for ML01DP5 but do you know if someone already made a pcb for this one and ESP8266 board (Weemos or other) ?

Very bad result with this PCB and Ebyte NRF24 PA+LNA module.
If the shield is distant from the Wemos D1 (not upside) it works fine. There is interference between ESP and NRF I think.

You can try TME. Lot of componments, very good service and delivery in 2 days.

@tbowmo After 2 month on the dev version, no more problem with the gateway. Perhaps it's time to made a new stable release ?

@scalz : any news about this problem ? I would like to move to the new driver but after reading this, I think it will be better to wait ;)

see here : https://www.eevblog.com/forum/eda/oshpark-plated-slots/

@tbowmo : Just flash my SBGW today with arduino 1.8.5, last boards.txt and dev branch of mysensors.
We will see if it's more stable. All my Node still in 2.1.1

@tbowmo : with wich RFM69 driver ?

I'm using version 2.1

I have a lot of problem with this gateway. First I think it was caused by network module but with serial sketch I have a lot of issues. After 2 or 3 days, gateway crash. If I remove some sensors reporting every 30 seconds it crash but later.
This morning, all leds are off on the board. After powering off and on it was ok.
I'im using RFM69 with Openhab2 as controller.
Is someone experience same issue ? I will fall back to my old Jeelink gateway (ATmega328 based).

And with RFLink, you can only use 2.4GHz frequency. It doesn't work with RFM69.
Actually I have a MySensors Gateway and a RFLink (not for the same usage)

With this setup, you don't have gateway feature in RFLink. You have to emulate Gateway with th host computer connected to RFLink (assigning NodeId, request presentation, manage acknoledge ...) I think it will be better and simplier to made a gateway.

@knop With an empty sketch, you have some packets from node to find parent (gateway).

It's probabley a request to find parent (t=07)

Hi,
After weeks of tests, it doesn't work well with ethernet and RFM69HW. Every 2 days, I need to power off and on the gateway. Controller can't connect (OH2).
for some reasons, serial doesn't work on my odroid C1 with openhabian.

@napo7 : you can use sleep with interrupts :

One test screenshot (not definitive) of my habpanel (openHab 2.0 part).
I'm using OpenHAB mysensors binding (from @TimO), node-red for rules, habpanel for UI, Tasker on android (for example open all RollerShuter just after morning alarm !).
I can access OpenHAB via nginx reverse proxy with https and on my LAN, home automation have a separate VLAN (for security reasons). Thanks a lot to @scalz for this module.

Some other photos (sorry, first one is not in the same room) :

Finnaly I find a solution with a very good WAF !
I want to keep a sort of manual command (not gateway or controller dependant) and I don't want an expensive solution (my ODACE schneider button are quite expensive and I don't want to buy other button).
But these button measure 38mm depth and @scalz board is about 20mm. My wall boxes are 50mm !
Si I find some special wall boxes with an enclosure for home automation module. It's cheap (about 3€) and very well designed (french RT2012 compliant). I update the sketch with MY_TRANSPORT_WAIT_READY_MS so node can work alone. And I update sketch to work with bistable button. Works well on 2 windows since yesterday.
