Chaps Not sure if this is the correct forum section as I haven't completed (or even begun) this project yet but am looking for suggestions and ideas as to how to proceed. I have a project in mind which involves automating some of the services in my caravan, although it could be applied to boats mo…

Folks. I went down the Raspberry pi zero 2 W route in the end and enabled it's hot spot to set up a small local network. I was going around in circles trying to use Termux on the Android phone. I may come back to it at some later date though. Thanks for everyone's help especially Colin as you've h…

[image] Surefire01: Sonoff wireless switches to control power to the space heating and water heating systems and monitor the temperatures with their temperature sensors. Not sure how your heating is controlled, but I know the protocols for my controller (Truma) don't seem to be available, or …

Mr Walker, my caravan is 16 years old so way before the time of fancy Truma controls. So yes I would just be switching the power on and off to the water heater and space heater with the Sonoff devices. I have been looking into TotallyInformation's suggestion of making the Raspberry Pi 2 W act as a …

I do this with an old android phone (with no SIM card). I installed node-red and mosquitto on the phone (with termux), and enabled the wifi hotspot on the phone. I use Sonoff devices (with Tasmota) to work the heating. The dashboard is visible on the phone for monitoring and controlling. By adding…

That sounds very interesting Colin. As it happens I've not long acquired a Huawei phone which has a faulty SIM slot so would be ideal for this project. I will investigate termux and have a go at installing node red and Mosequitto. Thanks

[image] Surefire01: I would power everything from the 12 volt system within the caravan using some 12 volt to whatever voltage required for these devices. As the caravan is permanently connected to 230v hookup, battery discharge will not be a problem except when towing on the road which will onl…

Thanks for the heads up homindae but would prefer to use stuff I have lying around.

Colin Have spent most of the weekend trying to get everything running on an Android phone. I installed Termux, installed Mosquitto in Termux, also installed Node red in termux. Spent ages trying to get everything to communicate. but can't seem to get my Sonoff TH16 to connect via MQTT to the Node r…

Do you have some other device (eg laptop) that you can connect to the Termux Access Point ? and then a) try to ping that address b) maybe try to run an MQTT client to connect to it. (eg MQTTexplorer) Is there any firewall in the way ? etc

See Running on Android : Node-RED, but also Getting started instructions for Android/Termux may be relevant. Let us know if you try it and agree with that post.
