Unfortunately, you have now jumped to using a different sensor (the BME280) and you are only using one sensor. Learn about sending messages between mobile apps using MQ telemetry transport (MQTT). The protocol is intended for use on wireless and low-bandwidth networks. A mobile application that uses MQTT sends and receives messages by calling an MQTT library. MQTT (Message Queue Telemetry Transport) is an ISO standard (ISO/IEC PRF 20922) publish-subscribe based “light weight” messaging protocol for use on top of the TCP/IP protocol. It is designed for connections with remote locations where a “small code footprint” is required or the network bandwidth is limited.

For example, you can subscribe to custom topics and extract telemetry values or attribute updates from it. Similar with ThingsBoard RPC calls. @calluminfra when you use devices I think it saves a timestamp with the latest activity, I guess you can just use the generator node to check all x seconds if the timestamp is still "new enough" (originator telemetry node) and based on that you may choose to save zeros by a script + save timeseries node. I think the main issue here is that ThingsBoard expects MQTT message in JSON format, meaning you send key-value like -m '{"value":20}.I do not recall any use cases where the message was a raw value, but I may be wrong.
