Ondilo

Ondilo accessories for connected pool and spa water monitoring

Ondilo is known for the ICO range of connected water analysers — floating devices that sit in a pool or spa, take readings from the water and send them to a smartphone app. Because that chain depends on a working wireless link between the device in the water and the home network, the accessories that keep the connection stable matter as much as the analyser itself. Here you will find the networking accessory side of the Ondilo range, intended for owners who already have an ICO unit installed and need the signal to reach it reliably.

Why connected analysers need a strong wireless signal

A floating analyser is, by definition, in the worst possible place for radio reception. It sits at ground level or below, surrounded by water, often behind a wall, a terrace door, a glass sliding panel or a spa cabinet — all of which absorb or reflect a 2.4 GHz signal. Routers, meanwhile, are usually indoors, sometimes on another floor and frequently at the opposite end of the house from the garden.

The result is a device that pairs perfectly during setup next to the router and then drops out once it is placed in the water. Readings stop arriving in the app, notifications go quiet and the unit appears offline even though it is working normally. In most cases nothing is faulty: the wireless path is simply too long or too obstructed. Adding a repeater between the router and the pool is the usual remedy, and it is far less work than moving the router or running cable to the garden.

What the Wireless-N repeater does

The repeater picks up the existing wireless network indoors and rebroadcasts it, effectively moving the edge of coverage closer to the water. Wireless-N refers to the 802.11n standard, which is the generation most smart pool and spa devices are built around; many connected analysers and controllers operate on the 2.4 GHz band specifically because it travels further through walls and foliage than 5 GHz.

• Placement — roughly halfway between the router and the pool or spa, in a position where the original network is still strong. A repeater can only rebroadcast what it receives.
• Power — a mains socket is needed at that point, so a covered terrace, a utility room, a garage or a pool house wall often works well.
• Band — check that your analyser is joined to a 2.4 GHz network rather than a combined or 5 GHz-only one, as this is a common reason for pairing failures.
• Network name — note whether the repeater broadcasts the same name as the router or a separate one, because the device must be pointed at the right network during setup.

Setting up and troubleshooting the link

Pair the analyser while it is close to the router or repeater, then move it to the water and watch whether readings continue. If they stop, the signal at the pool is the likely cause. Moving the repeater a few metres, raising it off the floor or choosing a socket on a less shielded wall often changes the outcome more than any setting does.

Also bear in mind that a spa cabinet, a metal cover, a solar roller or a pool enclosure frame sits directly in the path and can block a link that otherwise works. Testing with the cover open and closed is a quick way to identify that. Before ordering, it is worth confirming the wireless band your ICO unit uses and the password details of the network you intend to extend, since the repeater is configured against your existing network rather than supplied pre-linked to the analyser.

Here we list the Ondilo accessory that supports connected water monitoring in gardens and spa installations where the router is too far away to reach the device. It is a practical add-on rather than a measuring part: it does not change what the analyser reads, only whether those readings arrive.

The focus is on items that keep existing equipment working instead of forcing a replacement. If an ICO unit has fallen offline since it was moved into position, extending coverage towards the water is usually the first and cheapest thing to try, and this is the part that does it.
