    Well, I never returned to that topic, because I didn't need it. I think it still isn't implemented, but you have my code from that post, so you can try to modify your copy of Mysensors and it should work. If I remember correctly that was pretty simple modification, new version has probably changed, but not so much I guess.

    @zboblamont Thanks for the advice. I don't really want to 'fit' anything as I hope to move next year so something portable that I attach when I use the hose and then bring back inside is all I need. For the time being I have ordered one of those cheap Chinese flow rate sensors and a couple of hozelock adapters to get started with. Then I can take it up a notch from there if I want. Good thing about water for plants is no need for chlorine. After many years of doing this none of plants have complained! - And they include kaffir lime, lemon, tangerine, olive, banana, palms, lemon grass , chillies etc....

    @nca78 I understand your concerns and I would like to further sensing in this area - that sps30 you mentioned looks like a prime candidate for a future upgrade. Currently I take 20 readings at one second intervals and then average them. This happens once every 5 minutes and gives a graph plot like this...... [image: 1563015389376-dust.jpg] This is using the Sharp GP2Y1010AU0F but done the right way, not like the build page ;)

    @tsunami My setup is max 50m radius and 433MHz standard power RFM69s so a small 1/4 wave whip works reliably even from a below ground pump chamber 10m away. Your 915MHz at 200m SHOULD work on 1/4 wave if obstacle free line of sight, but you could try a 2.4GHz Wifi router at one location and use a mobile at the other to test if you can see the router. I can see at least 3 neighbouring routers identified on my mobile from over 40m away through masonry, 10 on the laptop, so it's a simple enough test. If you can see the router on either, 915MHz should be rock solid with a simple whip and no need of directional antenna.

    Perhaps a bit off the wall, but if the objective is an email out, are GSM signals strong enough even at another high point which does afford radio line of sight to the objectives? Used this many years ago for remote monitoring, in one case the GSM atop a 5m pole with a wind generator attached topping up a pair of batteries, so completely self sufficient. Links to the metering points were low power RF, the landowner had no objections. Only problems encountered were vandals climbing the pole, solved by a good coat of Copaslip ;) , and a Stag which regularly danced on a GRP cover to a flow meter chamber, to the great amusement of the gamekeeper :laughing:

    @mrhutchinsonmn you're right that the description and the sketch don't add up. They definitely need some work.

    This script will be more helpful for beginners. The previous script turns on/off all relays. This one controls only the specified relay. - id: '1562092064918' alias: Power Up Relay_2.1 trigger: - entity_id: switch.relay_4_2 from: 'off' platform: state to: 'on' condition: [] action: - alias: '' data: entity_id: switch.relay_2_1 service: switch.turn_on - id: '1562093186484' alias: Power Down Relay_2.1 trigger: - entity_id: switch.relay_4_2 from: 'on' platform: state to: 'off' condition: [] action: - data: entity_id: switch.relay_2_1 service: switch.turn_off

    @mfalkvidd Thank you, this should be the solution I'm locking for. Meanwhile I found the config-description...

  • Control Heatpump via Serial

    Hi, So as I see it I would need to use the hardware serial for the connection to the heatpump and then create a software serial for debug messages. So something like this: #include <SoftwareSerial.h> SoftwareSerial mySerial(10, 11); // RX, TX // Enable debug prints #define MY_DEBUG #define MY_DEBUGDEVICE mySerial #define MY_BAUD_RATE 9600 So the next question is how to present the heatpump to the gateway. Would you create one child id and then define each type of sensor/metric or is there a one-to-one mapping: #define CHILD_HVAC 0 MyMessage msgHvacStatu(CHILD_HVAC, V_STATUS); // Status: ON, OFF MyMessage msgHvacSTemp(CHILD_HVAC, V_TEMP); // Set Temp MyMessage msgHvacRTemp(CHILD_HVAC, V_TEMP); // Room Temp MyMessage msgHvacFanSp(CHILD_HVAC, V_HVAC_SPEED); // Fan Speed or #define CHILD_HVAC_STATUS 0 #define CHILD_HVAC_STEMP 1 #define CHILD_HVAC_RTEMP 2 #define CHILD_HVAC_FANSP 3 MyMessage msgHvacStatu(CHILD_HVAC_STATUS, V_STATUS); // Status: ON, OFF MyMessage msgHvacSTemp(CHILD_HVAC_STEMP, V_TEMP); // Set Temp MyMessage msgHvacRTemp(CHILD_HVAC_RTEMP, V_TEMP); // Room Temp MyMessage msgHvacFanSp(CHILD_HVAC_FANSP, V_HVAC_SPEED); // Fan Speed

    MQ are always a bad choice, saturate air around with any gas and they will react ... Mics are used by sensely, but even them aren ot calibrated... and they are a hell to get working even when you have the pins soldered to them.

    @yveaux said in MY_RF24_IRQ_PIN on ESP8266 GW: True, and next it doesn't use it? ;-) This could be reformulated as an affirmative sentence. I cut the bridge wiring and continued working as nothing happened.

    @mfalkvidd Today it did some real testing with the actual setup (not a test node) and it is all working really well so far. I was expecting to have to use limit switches to detect up and down limits, with microswitches to provide emergency power cut out to the motors if it overran. I even considered timing the motion too (done this with Crestron systems and curtains in the past). But I have had two really great surprises...... The little stepper motors, when set within their comfort zone, are very precise. It looks like just counting steps is all that is required. The steppers draw just 77mA when opening the blind. This is such good news for me as solar powered blinds (with li-ion or lead acid battery) will last all year! Big thanks to you all for the hints and finding where I mis-understood. It won't be easy, but I will get there in the end. ;)

    thanks all the design has changed I plan to heat some medium and have the water pass though a head exchanger what way standing water will never be consumed later there is a commercial product called sunamp which is designed for this purpose
