Hello, I’m Buğra Demiriz. At Hermetry I work on the software side and on use cases, which mostly means the ready solutions and automation.
A ready solution is a complete application built only from parts every organisation already has: device profiles with their keys, alarm rules and commands, sites and assets, a board with several pages, and flows. There are five of them: water site, remote sites, weather stations, sensor regions and personnel tracking. Nothing in them is special, so you can open any part, copy it or change it.
Automation means flows. A trigger starts a flow with a message, and blocks check, route, transform, store and act on it. A flow runs only after you deploy it, and every deploy is a numbered version you can roll back to.
I’ll pick up questions in Rules and flows, Webhooks and integrations and REST API, and the «how would I build this» kind where a solution is a good place to start. Start from Ready solutions and Flows. If you share a flow here, use its export: secrets are never in a flow export. Still check the payloads for names and addresses before pasting.
Hi Buğra. Can a flow send readings to our own HTTP endpoint? And the other way round, can one of our services push data into a flow?
Both. Going out, the HTTP request, MQTT out and Webhook blocks send data. Coming in, a Webhook trigger starts a flow with the request body. One decision first: every flow belongs to a host, IoT or General, chosen when you create it and never changed. Anything that works on device messages goes on IoT; a job that only moves data between your systems can sit on General. See Hosts, the root flow and profile root flows.
Water site sounds very close to my day job, tanks and pump stations. Is it included or does it need something extra on the plan?
The solutions are part of the IoT add-on. Water site covers tank levels against thresholds, pumps, phases, thermal relays, pressure, flow, manual pump commands and a process diagram. It expects keys such as level_cm, and your devices almost certainly send other names, so read Adapting a solution to your devices before you start mapping.
