Flood water sensor and water meter reading

[paul402]

Had planned to visit bad injured son in hospital in another country when I discovered last Friday that the boiler had been leaking 18 liters/day into the cellar sub-floor. Hidden by the flooring the damp showed up to a meter high in the concrete cellar walls.
That's going to be expensive. The dryer company reckons 2 to 3 months with 3 dryers and the insurance company has agreed to 3k euros electricity.

So any recommendations for a flood water sensor with 433 MHz capability to RFXCOM and a heartbeat battery status signal?

Oh we have a digital water meter which if I was able to monitor it would have shown the continuous loss through the night.
The unit is a Diehl Type 173. I asked the water supplier if it was possible to interrogate and they said "No". Has anyone been able to sniff pulses from it?

I'm curious. Has no-one ever done this before with Domoticz? Am I breaking new ground?
Or is it the case that everyone knows about it already?
Anyone recommend another forum that might have some answers for me?

Mine are ZigBee (aqara) as I don't trust the 433 mhz protocol (no guaranteed delivery).

Thanks heggink. What do I need to get started with Zigbee and connected to Domoticz? This is new territory for me.
Is there a tutorial?

ZigBee is worth it. Much better than 433 and far cheaper than zwave
I can help set it up. There's multiple working options. I chose to use zigbee2mqtt as domoticz has native support for the autodiscovery protocol.
You would need a zigbee usb stick (I have the zzh stick but there are others that are as good or better) to connect zigbee2mqtt to ZigBee devices.

Have a look at the zigbee2mqtt site. It is pretty solid. I run zigbee2mqtt in a docker container. Literally up within a minute.

+1 for Domoticz + zigbee2mqtt in Docker and a ZZH stick. Working great for over a year and much more reliable than 433mhz which I used before. Batteries in my sensors last for +1 year and still going strong.

I use the Shelly Flood in combination with MQTT and ShellYMQTT. Works directly with Domoticz without further hardware.
