Unless you make progress on this yourself you need to do the following to get more help. Post links to the items you are trying to use. Post links to the libraries you are using to achieve this. Post your code. Without the above it's all a shot in the dark.

Thank you @dzjr I am not sure how it happened, but I am also very happy of the pleasant and supportive tone on the forum.

I recently read that if you use multiple USB gateway then you can't have duplicate of child is. Maybe this is a clue

Hello friend, any progress on this ? I plan to buy a power meter and it would be awesome to read it over my existing rs485 mysensors network ? can mySensors and modBus protocol coexist on the same physical line ?

@monte said in Best choise for a controller: @neverdie but isn't Docker more efficient and simple solution compared to a VM? Considering it will be used for single process anyway. Yes, I think you're right.

Check out the reply I got. Hope it helps you too. https://www.domoticz.com/forum/viewtopic.php?f=6&t=28925&p=220914#p220916

@flyingdomotic I tried that, only then the text status will not appear in domoticz. I didn't use/tried it for the analog value, maybe i'll try that, thank you!

Hi @bgunnarb Thank you for the reply, I use a directly fed (RS485) sensor (network), partly because I use a 24VDC power supply for the heater on the rain sensor (the rain evaporates faster) So I don't need to increase the interval to save batteries, but I will definitely take your tip about the smooth curves with you. I want to create a script in the controller for the LUX value for controlling the garden lighting, for example turning on the light at a lux value <300, and turning it off again at a lux value> 500 or something like that. in the sketch I have now made a separate time interval for each sensor, which is actually because I am still searching for the ideal values of the rain sensor.

@electrik I already dit set it at 0,5 so it is changing 1 degree. I now have made it even 0.05 so i can change it by 0,1 degree. Thanks for all the help!

I have now been running the gateway for more than half a year, and unfortunately the gateway runs regularly (about once every 2 weeks), so I am going to replace the gateway for a W5100 ethernet adapter. I used it in a second gateway, and this gateway is stable, I haven't had any crashes in about 4 months.

@dzjr Yes it is, in theory. it's a three-way valve. I haven't tested it yet though. For now my plant health monitor just monitors 6 plants. It's part of a large project about privacy in the smart home that I will be revealing in the coming year.

@zboblamont said in Multiple Dallas Temperatuur sensors at one sensor node: If you cannot daisy chain them because there is no sequential route between locations, use a separate pin for each data line (powered via resistor) and communicate with each line in turn. The line here is using 3 cores in 20-30m of Cat5e cable to ensure each chip is physically sequential on the line. When I added a further sensor location, a loop had to be spliced in to keep the line a daisy chain. It is a small house, the length is purely down to the route, and cable is cheap. in case you can not daisy chain them because there is no sequential direction among locations, use a separate pin for each data line (powered thru resistor) and talk with each line in flip. the road here is using three cores in 20-30m of Cat5e cable to make certain each chip is physically sequential on the road. after I delivered a similarly sensor vicinity, a loop needed to be spliced in to preserve the road a daisy chain. it is a small residence, the period is purely down to the route, and cable is cheap.

@hek aha, clearly, I've looked over it, I think ...

@gbuico

@hard-shovel That would be the cold coffee with cream with a certain Guinness ais quoi?

@alowhum said in How to build up a sensor network: @dzjr sound like quite a plan. Why not directly connect the radio to your Raspberry Pi's GPIO pins? It's easy, and will save you an Arduino. This might be interesting to check for your irrigation needs: https://forum.mysensors.org/topic/9534/irrigation-controller/8 This might be interesting to check for your heater: https://forum.mysensors.org/topic/9421/safe-heating-with-mysensors-how-i-use-it-as-a-smart-thermostat Thank you for replying I will read the post's, and of course also use it during programming. The reason I use separate arduinos is that I want to set up the (rapsberry-Pi) domticz server in the house, in a central cabinet together with an RF-Link and a second MySensors gateway. Also, a Raspberry-Pi only has a limited number of GPIOs (eg wants to control 16 relays), and no analogue inputs, but I could still read that via an i2c multiplexer.
