    @mrhutchinsonmn Just replace it. It has the same 8-pin interface as the other ones. Please be aware that the E01-ML01DP5 aren't magical bullets either. They allowed me to reduce the amount of repeaters in our house from one on every floor to one on every second floor (steel reinforced concrete ceilings), but the advertised 2500m range is unrealistic in real world scenarios. Their biggest plus for me are the improved reliability and stability they provide compared to cheap amplified modules, especially at high PA levels. BTW - I just saw that they are selling this module for 2,76 EUR / 2.92 USD in one of their other stores in the upcoming sale event, starting on monday: https://www.aliexpress.com/item/33013542366.html

    @mfalkvidd said in RS-485 to an wireless Gateway: Most controllers, including Domoticz, supports multiple gateways. I have 2 gateways on my Domoticz. That's what i wasn't sure. Right now i already have a zwave gw(module) hoked to raspberry pins,that controls all windows shutters and an Usb GW (mysensors serial gw) that controls 4 temperature sensors, irrigation valcs from my garden ,solar water panel relay , outdoor lights etc...all on rfm69W and C "transport" 868mhz, but i will consider if i build a second arduino usb GW or i keep the wireless to the gate. So if i see the zwave module like an GW i already have 2 as well :confused: The true it's that the gate is already "mysensor-rized" with wireless but i keep preferring wired connection for outdoor and once i'm burying the cables for power and doorbell ,maybe i add an Cat6 cable for RS-485 connection.

    I like the lighting effect on the stairs too. It looks great.

    It's not a perfect pin-out match. You should definitely check out this thread: https://forum.mysensors.org/topic/10327/rf-nano-nano-nrf24-for-just-3-50-on-aliexpress/1 But you're right, it's great for beginners. That's why it forms the basis of the Candle project.

    @Anduril Well, its all opensource, so you are free to do whatever you want. Just remember that if you are starting to alter the behaviour and use of the security infrastructure, you could potentially compromise it for yourself and those that use your code.

    No, I didn't seriously consider it. I have a minimal programming circuit with ZIF-sockets to program DIPs, but those are easily removed from a circuit (assuming they are put into sockets and not soldered) in case they need to be reproprammed . Doing this with a TQFP seems like a one-way road, so I think a way for in-circuit programming should be provided regardless. I mean, I didn't have to reprogram my first revision nodes so far, but I might want to add signing support later on or upgrade to MySensors 2.4 or 3.0 for some reason, so it should definitely be possible, but I'm not too worried, if the programming process is a little cumbersome, if the SOICbite experiment doesn't work out.

    @mfalkvidd said in What happened to ceech?: I don't know, but according to https://forum.mysensors.org/user/ceech last time online in this forum was September 2017. His eBay shop is empty. Not a good sign...

    @mirodin said in How to power my sensors in a rental?: using normally closed reed switches You can "convert" those by reverting the orientation of the magnet on your door, then adding another magnet (weaker or further away) inside the node enclosure to keep the reed switch closed when you open the door. When the door is closed the reversed magnet on the door will open the reed switch. To do even better you can use : reed switches with 3 leads that work as both normally opened and normally closed switches, and wire them to the 2 interrupt pins. I used that on my first nodes and managed to get reeeeaaaally long battery life on a simple CR2032. When door status changes the node is woken up then you set pin low and current could run only a very short time, you send the message with new status then you activate the other interrupt pin and go back to sleep https://www.aliexpress.com/item/33028519094.html if you're not afraid with SMD there are some ultra low power hall switches, using less than 1uA of current like the DRV5032.

    I also suggest using MP3 shields and modules with jack output.

    @benhub do you have the code the links seem dead? Ive been trying to get 2 temp/hum sensors (DHT22) working in domoticz for quite a while now with no luck. The temp/hum data in domotcz keeps swapping around from one sensor to the other and i cant work out why.
